Product Availability When It Matters Most – A Case Study

When PTI’s on-call employee learned an aggregates manufacturer needed a large split block housing ASAP because of a conveyor failure on a Sunday, he immediately got to work…

PTI-Case Study-image for email
The Challenge: One of a large cement and aggregates manufacturer’s Midwest plants was in operation on a Sunday morning when one of their large split block housings failed on the conveyor, halting operation. The manufacturer needed a replacement part as soon as possible, but their distributor learned that their existing supply base didn’t have any housings available in that size. It’d be a 10-12 week lead time to get a replacement.

The Solution: The distributor contacted PTI’s local sales representative, who then reached PTI’s after-hours service. Our on-call employee interchanged the competitor’s part number, checked inventory, and quickly confirmed that the required unit – a metric plummer block with a 240mm shaft (PTI Part No. SD3152TS) – was in stock at our warehouse in Charlotte, NC. The distributor then emailed a purchase order to us and coordinated transport with an air freight courier.

SD3152TS
(The Solution continued): Because the housing just barely exceeded the air freight weight limit, we removed the cap from the base and packaged them on separate pallets. The courier transported the pallets to the airport to be shipped out that evening. The receiving airport freight department was closed for the night, so the housing was picked up early the next morning. It was transported 150 miles and arrived at the plant Monday morning at 8:30 a.m. local time.

The Result:
With PTI’s 24/7 availability and experienced staff, the manufacturer was able to get a replacement part in less than 24 hours. The distributor also enjoyed a significant savings of 38% by using PTI, which helped off-set the courier and air freight charges.

6 Key Features of a HT Mounted Ball Bearing

High temperature applications require mounted ball bearings that don’t just withstand the heat, but that also ensure your application remains safe and operational…

Here are 6 key features to look for when choosing a high temperature (HT) mounted ball bearing:

  1. High Temperature Lubrication: A high temp bearing will still fail prematurely without the correct lubrication. Lube fill rates are typically 35 to 55%, but for low speed or frequent wash-downs, we recommend higher fill rates.*
  2. C4 Internal Clearance: C4 ensures there is more internal clearance to accommodate thermal growth of races vs. the standard C3 clearance.
  3. Heat Stabilized Races & Steel Cages (aka Retainers): Why? These can handle higher temperatures and the cage will not become brittle like polyamide or glass fiber cages.
  4. Anti-Rotation Pins on the Bearing Insert’s OD (Outer Diameter): These help to both align the insert easily and restrict rotation due to temperature fluctuations.
  5. High Temperature Silicon Bearing Seals: These provide added protection from elevated temperatures and corrosive environments up to 390F (200C). Stainless steel flingers are standard on PTI high temperature bearings and can be removed if needed.
  6. Clearly Marked and Tagged Housings: Last but not least, it’s crucial that those individuals installing and maintaining the bearing will recognize it as a high temperature bearing and will use the proper lubrication.

*PTI Engineers are available to help consult on proper lubrication options for heavy load applications.

Engineering to Client Specifications – A Case Study

PTI-Case Study - Engineering to Client Specifications image for email

The Background: A well-established distributor supplies bearings, belting, electrical equipment and more for the electrical, power transmission, and automation industries. They regularly purchase a two-bolt flange mounted ball bearing for their customer from a competing manufacturer.

The Challenge: The distributor was becoming increasingly unhappy with longer lead times from their existing supplier and learned that the supplier was planning to discontinue the product. PTI’s local sales representative shared PTI’s lead times, pricing and standard part dimensions with the distributor. PTI’s price and delivery were satisfactory, but the length through bore (LTB) dimension was slightly longer than the customer’s application allowed.

Here are the Top 10 Reasons Why Bearings Fail:

  1. Ineffective / Wrong Type of Lubrication*
  2. Insufficient Amount of Lubrication*
  3. Excessive Amount of Lubrication*
  4. Misalignment
  5. Contamination
  6. Inadequate Bearing Clearance
  7. Undersized Shafting
  8. Imbalance in the System
  9. Improper Bearing Selection for Application
  10. Improper Mounting / Handling

*Lubrication is the #1 cause of failure. Typically a little bit of grease at frequent intervals is better than a lot of grease at infrequent intervals. Click here to view more lubrication tips.

Expertise in European and Metric Manufacturing – A Case Study

PTI Engineers designed an improved version of a stainless steel custom chain with metric attachments that a US food manufacturer had been purchasing from Europe…

case study image - cropped for email smaller.jpg

The Background: A major producer of gourmet meats and cheeses generates over $3 billion in annual sales. They utilize a large chiller application for processing meat.

The Challenge: Their equipment uses a 750 foot long stainless steel chain with metric attachments. The food producer had been sourcing the chain from an Original Equipment Manufacturer (OEM) in Italy. However, that purchase was outside of their normal procurement process, had to be converted from euros to dollars, and incurred additional importing fees and taxes. The company was seeking both greater efficiency and a lower total cost without sacrificing quality.

3d rendering of chain.PNGThe Solution: PTI’s Sales and Engineering Teams worked with our local distribution partner to gather specifications from the food producer along with a sample of the chain they were currently using. After examining the product details, PTI was able to replicate the chain to meet the customer’s specifications and quality standards. PTI also standardized the location of pins so that the holes were parallel with the links, resulting in easier installation and a more uniform appearance.

Custom Product Engineering – A Case Study

Here’s a step-by-step account of how PTI’s Engineering Team worked with an OEM to customize an existing housing for a new application…all in just over two months:

case study image cropped for email.jpg

The Background: A large, US-based OEM (Original Equipment Manufacturer) supplies drying equipment for commercial use. Their products include machines such as industrial grade large capacity dryers, coin operated dryers, and drying equipment.

The Challenge: The OEM discovered the bearings of their drive motors were overloaded and prone to premature failure. While needing a very light swivel fit for the bearing within the housing during installation, the customer also wanted the ability to lock the bearing down in the housing after motor and drive components were aligned and adjusted. Ultimately, they wanted a new adjustable clamp type housing.

The Solution: PTI’s Engineering Team worked with the customer to understand and analyze the application needs.

cropped - just case study process.png

The Result: This new housing allowed all drive components to be aligned and installed first, then the bearings could be clamped into position. Due to the lube-for-life feature desired by the customer, PTI recommended a 60% lube fill to allow as much lube for the best possible service life.

The project length from initial contact to completed production units took less than three months.

PTI’s Ability: By utilizing PTI’s engineering capabilities, customers benefit from dedicated, knowledgeable, and creative problem solving even under very compressed time frames. PTI remains committed to cutting-edge engineering capabilities and top-notch customer service.

The Four Shaft Attachment Methods

PTI proudly offers all four insert types for mounted ball bearings: Setscrew Locking, Eccentric Locking Collar, Concentric Clamp Collar and Tapered Adapter Sleeve. Understanding the features of each and the differences between them will help ensure you’re using the best shaft attachment method for your application.

grouped shaft attachment methods.jpg

SETSCREW LOCKING
How it works: Two screws are tightened to clamp the bearing onto the shaft. The contact between the bearing and the shaft is concentrated on the opposite side of the setscrews. This is the most popular mounting method.
Note: Setscrews can cause significant fretting corrosion, making removal very difficult after years of operation.

ECCENTRIC LOCKING COLLAR
How it works: As the collar is twisted into place, it locks the bearing to the shaft. The contact of the bearing is slightly more distributed than the setscrew locking method.
Note: These are unidirectional and are not intended for reversing loads. Like the setscrew method, the eccentric locking collar can cause significant fretting corrosion, making removal very difficult after years of operation.

CONCENTRIC CLAMP COLLAR
How it works: Tangs on the extended inner ring of the bearing lock down when the collar is twisted into place. The contact of the bearing is evenly distributed within a small area around the shaft.
Note: This is a good method to use to minimize vibration.

TAPERED ADAPTER SLEEVE
How it works:
This bearing has a tapered adapter, a locking washer, and a locking nut. As the locking nut is tightened with a spanner wrench, the adapter is drawn through the bearing and tightened to the shaft. The contact of the bearing is evenly distributed around the shaft.
Note: This bearing has the highest purchase price and will take the longest to install, but allows for minimal shaft damage and highest possible speeds with the least amount of vibration.
