Constant Section (CS) Bearings JA040XP0

Constant Section (CS) Bearings JA040XP0

The JA040XP0 is a thin-section ball bearing with a 4-inch bore and 4.5-inch outer diameter, designed for four-point contact. Its compact width of just 0.25 inches makes it ideal for space-constrained applications. The sealed construction keeps lubrication in and contaminants out.

Made from chrome steel with a brass cage, it handles radial loads up to 756 lbf and thrust loads up to 1210 lbf. It operates smoothly in temperatures from -30°C to 110°C, suitable for various environments. The ABEC-1 tolerance ensures reliable performance without excessive precision demands.

This bearing is interchangeable with KAYDON models, offering a practical replacement option. Its Reali-Slim design is perfect for robotics or medical equipment where slim profiles are essential. Weighing only 0.19 lbs, it’s lightweight yet durable.

Pre-lubricated and RoHS compliant, it’s ready for installation straight out of the box. The sealed design reduces maintenance needs, making it a hassle-free choice for long-term use.
