Description
Description
Description: Cat bearings are designed for specific applications based on load, operating speed, temperature range, size, and past performance. Cat bearings are manufactured to the highest quality standards for long life and performance. Cat cylindrical roller bearings with a cage accommodate heavy radial loads, rapid acceleration and high speeds. Full-complement cylindrical roller bearings are suitable for very heavy radial loads at moderate speeds. High-capacity cylindrical roller bearings provide both heavy radial capacity and very high speed capacity. Cat cylindrical roller bearings are built specific to their application to ensure all drive train parts work together as a system.
Attributes: • Outer race and roller assembly • Heavy press outer race
Application: Cat cylindrical roller bearings are typically used in transmission and axle systems, pinion and transfer gear assemblies and clutch systems.
Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
