RE Crossed Roller Bearings RE25030UU

The RE25030UU is a crossed roller bearing with a 250mm bore and 330mm outer diameter, designed for combined loads. Its compact 30mm width makes it suitable for tight spaces, while the double seals keep contaminants out.

Made from durable steel, it handles loads up to 126kN and is rated for temperatures from 0°C to 110°C. The press-fit shaft mount ensures a secure installation, and greasing holes simplify maintenance.

This ABEC5-rated bearing (also available in higher precision grades) is ideal for rotary tables or robotic arms where precision and stability matter. Compliant with RoHS and REACH standards, it’s a reliable choice for industrial applications.

Weighing 8.1kg, it’s robust yet manageable for its size. The design includes minimal shoulder heights (269mm max and 306mm min) for flexible mounting options.
