RB 7013 UU CO THK Cross Roller Bearing 70x100x13

Industrial Applications of THK RB 7013 Cross Roller Bearing

The THK RB 7013 UU CO cross roller bearing is designed for high-precision industrial applications requiring exceptional rigidity, accuracy and compact design. Thanks to its cross-roller construction, this bearing can simultaneously support radial loads, axial loads in both directions and tilting moments within a single bearing unit.

It is widely used in rotary tables, industrial robots, CNC machines, automation systems, positioning devices and precision measuring equipment. The bearing is suitable for direct installation in a bearing housing or as a core component of a compact bearing unit where space saving and precision are critical.

Advantages of RB 7013 UU CO THK Bearing

The RB 7013 bearing features cylindrical rollers arranged alternately at 90 degrees, enabling uniform load distribution and very high system stiffness. This design eliminates the need for multiple bearings and significantly improves positioning accuracy.

Double-sided UU sealing protects the internal rolling elements from contamination, ensuring long service life and stable performance in industrial environments. The CO clearance class provides controlled internal clearance, supporting smooth rotation and repeatable motion in precision applications.

Manufactured to THK quality standards, the bearing delivers high durability, low friction and reliable operation even under complex load conditions.
