Crossed Roller Beairngs

Crossed roller bearings are a type of roller bearing with cylindrical rollers or tapered rollers are arranged perpendicular to each other in a V-shaped groove. The rollers are placed alternately at 90-degree angles, which allows the bearing to support loads in all directions: radial, axial, and moment loads (tilting moments).

ZMS is a professional crossed roller bearing supplier in China. We supply high quality crossed roller bearing that good substitute of THK,IKO and INA that customer can afford.

The material can be: 42CrMo, GCr15, 9Cr18.

And the precision can be P5,P4 and P2.

We supply series:
– Standard Crossed Roller Bearings.
– Thin-Section Crossed Roller Bearings
– Split-Type Crossed Roller Bearings

THK series including:RB series, RE series, RU series, RA series,XR series.

IKO series including: CRB series, CRBC series,CRBS series, CRBE series, CRBH series, XSU series.

INA series including: XSU series, XU series, XV series, XSI series.

High Rigidity

The crisscross arrangement of cylindrical rollers increases rigidity and minimizes elastic deformation, making them ideal for precision applications.

High Rotational Accuracy

The rollers are arranged at right angles to each other, allowing precise rotation with minimal clearance and high running accuracy.

Ability to Support Loads in All Directions

Capable of simultaneously supporting radial loads, axial loads (in both directions), and moment (tilting) loads with a single bearing.

Compact and Space-saving Design

One crossed roller bearing can replace a combination of several conventional bearings, reducing space and weight in machinery.

Smooth Rotation and Low Friction

Rollers are separated by spacers, preventing contact between rollers, reducing friction, and ensuring smooth motion.

Easy Installation

Many designs (especially integrated types) have mounting holes, simplifying installation and alignment.
