RA Crossed Roller Bearings RA5008C

RA Crossed Roller Bearings RA5008C

The RA5008C is a compact crossed roller bearing with a 50mm bore and 66mm outer diameter, measuring just 8mm wide. Made from sturdy steel, it handles combined loads up to 5.1 kN with ease.

Its single-row design offers precise motion control, while the open construction allows for straightforward lubrication. The bearing operates smoothly in temperatures from 0°C to 110°C.

With a press-fit shaft mount, it stays securely in place during use. The ABEC5 rating ensures reliable performance, though higher precision options (ABEC7/9) are available.

Ideal for rotary tables or robotic arms where space is limited but precision matters. Compliant with RoHS and REACH standards, it weighs a mere 0.08kg for easy handling.
