CRBTF Crossed Roller Bearings CRBTF305AT

CRBTF Crossed Roller Bearings CRBTF305AT

The CRBTF305AT is a compact crossed roller bearing measuring 30mm in bore, 63mm in outer diameter, and just 5mm wide, made from sturdy steel for reliable performance. It handles combined loads with a basic load rating of 2.14 kN and operates smoothly in temperatures from 0°C to 110°C.

Its single-row design with open construction and mounting holes (8-M2.5 inner, 8-φ2.9 outer) ensures easy press-fit installation. The precision ABEC5 rating (upgradable to ABEC7/9) makes it suitable for high-accuracy applications.

This bearing is ideal for rotary tables, robotics, or medical equipment where space is limited but precision is key. Lightweight at 0.083kg, it meets RoHS and REACH standards for safe use.

Regular lubrication is recommended to maintain its smooth operation over time. The crossed roller design provides excellent rigidity and stability under load.
