RB Crossed Roller Bearings RB25025

RB Crossed Roller Bearings RB25025

The RB25025 is a crossed roller bearing with a 250mm bore and 310mm outer diameter, crafted from sturdy steel for reliable performance. It handles combined loads up to 69.3 kN and is designed for precision applications.

Its single-row construction and open design make it easy to maintain, while the press-fit shaft mount ensures a secure installation. The bearing operates smoothly in temperatures from 0°C to 110°C.

With an ABEC5 rating (also available in higher precision ABEC7/9), it’s ideal for high-accuracy machinery like robotics or CNC equipment. The compact 25mm width saves space without sacrificing strength.

Weighing 5kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a safe choice for industrial use. Regular lubrication will keep it running smoothly for years.
