266-6334: 40mm Internal Diameter Single Row Ball Bearing

Description: Ball Bearings reduce friction and provide protection between mating parts. They are specifically designed for high speed, low load applications with little to no side thrust. Attributes: Caterpillar spends significant amounts of time and money on research and development to ensure every Cat bearing meets specific design and application requirements. Many incorporate one or more special features not found in industry standard bearings. The net result is a reduction in the number of repairs required, along with reduced downtime and operating costs. Recommended Application: Cat bearings are built specific to their application to ensure all drive train parts work and wear together as a system.
