RE Crossed Roller Bearings RE30040

RE Crossed Roller Bearings RE30040

The RE30040 is a crossed roller bearing with a 300mm bore and 405mm outer diameter, designed for combined loads. Its single-row construction and open seal type make it easy to maintain, while the steel rings and rollers ensure durability.

With a basic load rating of 212 kN, it handles heavy loads efficiently. The bearing operates smoothly in temperatures from 0°C to 110°C and is press-fit for secure mounting.

Greasing holes (6mm and 3.5mm) allow for easy lubrication, extending its lifespan. The ABEC5 rating ensures precision, with options for higher grades (ABEC7/9) if needed.

Ideal for industrial machinery and robotics, this bearing is RoHS and REACH compliant. Weighing 17.2kg, it’s robust yet manageable for its size.
