Bearings

Bearings for Caterpillar equipment are essential precision components designed to reduce friction between moving parts, support heavy loads, and ensure smooth, efficient operation in engines, transmissions, drivetrains, undercarriages, and other critical areas of CAT machinery. Propel Parts offers a comprehensive selection of these bearings, including ball, roller, tapered, needle, and thrust types, covering over a thousand options to match the exact requirements of various CAT equipment models. Each bearing is manufactured using proprietary processes, special heat treatments, and materials engineered to handle the specific loads, speeds, temperatures, and environmental challenges encountered in heavy equipment applications.

CAT bearings feature unique technologies such as debris resistant construction and textured surfaces, which are proven to significantly extend service life by preventing contamination damage and reducing metal to metal contact in slow speed, high load conditions. These bearings are manufactured to precise tolerances, ensuring proper alignment and fit with other drivetrain components, which helps prevent premature gear failure and costly downtime. Regular inspection and timely replacement of worn bearings are essential for maintaining machine reliability, minimizing maintenance costs, and extending equipment life.
Propel Parts provides a wide range of genuine or high quality bearings for Caterpillar equipment with clear specifications and fast shipping, supporting efficient maintenance and repairs for CAT owners and technicians.

Our Copper/Lead bearings are made of a sintered trimetal with a base alloy copper, lead and tin with a nickel dam and Babbitt top layer. The F780 alloy has a higher load carrying capacity than aluminum or other copper/lead alloy. As a result of this advance technology material, F780 will provide longer life in normal operation and significantly improved fatigue resistance under extreme operating conditions. We also have available engine bearings made of aluminum, alloy, and other materials
