71800 CD/P4DGAVT105F2 Bearing Product Overview & Core Advantages
The 71800 CD/P4DGAVT105F2 is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and high-speed performance. This bearing is characterized by its extra light preload (Class A) and universal matchable (SU) design, allowing for flexible mounting arrangements in pairs to support combined loads. Manufactured from high-grade chrome steel with a phenolic cage, it offers reliable operation and is pre-lubricated with grease for immediate use. Its compact design, featuring a 10 mm bore and 19 mm outside diameter, makes it ideal for high-precision, high-rigidity applications where space is at a premium.
