Constant Section (CS) Bearings K12008AR0

Constant Section (CS) Bearings K12008AR0

The K12008AR0 is a slim metric ball bearing with a 120mm bore and 136mm outer diameter, measuring just 8mm in width. Made from chrome steel, it’s designed for angular contact loads and fits tight spaces without sacrificing strength.

It handles radial loads up to 1294 lbf and static thrust loads of 3086 lbf, with a 30° contact angle for smooth operation. The brass cage ensures durability, while the open design allows easy lubrication.

This bearing is interchangeable with KAYDON models and meets ABEC-1 tolerance standards. Its slim profile makes it ideal for robotics or precision machinery where space is limited.

Weighing only 0.16kg, it works in temperatures from -30°C to 110°C and complies with RoHS standards. A reliable choice for applications needing compact yet robust performance.
