Constant Section (CS) Bearings JB040CP0

Constant Section (CS) Bearings JB040CP0

The JB040CP0 is a sealed radial ball bearing with a 4-inch bore and 4.625-inch outer diameter, designed for thin-section applications. Its compact width of 0.3125 inches makes it ideal for space-constrained setups.

Made from chrome steel with a brass cage, it handles radial loads up to 825 lbf and operates smoothly in temperatures from -30°C to 110°C. The sealed design keeps lubrication in and contaminants out.

This bearing is interchangeable with KAYDON models, offering a reliable replacement option. Its ABEC-1 tolerance ensures consistent performance for light to moderate loads.

Weighing just 0.3 lbs, it’s a lightweight choice for applications like robotics or precision machinery where slim profiles are needed. Compliant with RoHS standards for safe use.
