  • Innovation Aha Moment: CVT - Clutch Roller Bearing
    The clutch roller bearing has not changed in a number of years. Depending on the application, four to five pieces are added during production as separate entities. John Zajeski, a senior bearing specialist, took a look at the process and realized an opportunity to consolidate the individual pieces
  • Factors to Consider When Choosing a Crossed Roller Bearing (.pdf)
    For the lack of the right bearing, the kingdom of ever-faster microprocessors might have been lost. But this story has a happy ending. Technical achievements in microprocessor manufacturing, diagnostic equipment and automation have demanded increasingly more precise motion control. Whether
  • Bearing Closures - Bearing Seals and Bearing Shields
    Ball and roller bearings are available with different types of shields and seals. These are commonly referred to as closures. Closures can extend bearing life by preventing contaminants from reaching the critical surfaces inside the bearing, and they help retain the lubricant in the bearing
  • Bearing Materials
    Bearings materials are classified as through-hardened materials (used largely for ball bearings) and case-hardened materials (used largely for roller bearings). Critical applications require vacuum-processed steels. Regardless of material type, a commonly accepted minimum hardness for bearing
  • Spherical-roller bearings graduate to a new class
    Advances in materials, design, and processing have combined to triple bearing life. EDITED BY KENNETH J. KORANE Explorer bearings are available in both sealed and unsealed versions, and are dimensionally interchangeable with existing spherical-roller bearings. They have higher load ratings and up
  • Adjustable Bearing Preload Solutions
    Angular roller bearings and ball bearings in an assembly typically require preloading in order to maintain a minimum designed axial force in the assembly. This minimum force is called the bearing preload and is designed to overcome the stack up of tolerances within the assembly and ensure no slop
  • The Latest in Slewing Ring Bearing Technology
    If youâ ve ever been in the market for a slewing ring bearing, you may have found the number of available options to be somewhat limited. Roller slewing rings have been the only choice for rotating or turntable applications, but for your next project you might want to consider a new technology
  • New Spins on Bearing Technology (.pdf)
    Nook Industries provides a complete selection of inch and metric Ball Screws, Roller Screws, Acme Screws, Lead Screws, End Bearing Supports, Precision Locknuts, Worm Gear Screw Jacks, Electric Actuators, HRC 60 Linear Shafting, Linear Bearings and Pillow Blocks to the Linear Motion Industry
  • Answers to the 5 Most Asked Bearing Questions
    Bearings play an important role in just about everything that moves - from fans and roller skates to ATVs and hospital beds. As a manufacturer, CCTY Bearing fields a lot of questions about bearings and bearing assemblies. Below are the most common bearing questions we receive.
  • NASA - Roller Bearings to Millionths
    The lead tribology Metrologist of one NASA laboratory stated "The radial internal clearance and axial internal clearance kits for the Labmaster Universal will help further establish us as a very capable bearing research lab."
  • Bearing Swap: If You Can't Take the Chill, Get Out of the Cooler
    . The conveyor-roller shafts originally rode on wood-and-resin bearings that relied on moisture for lubrication. But the conveyor's loads led to uneven bearing wear, specifically elongation of the inside diameter because the bearings remain stationary while the roller shaft spins. The original bearings
