RB SERIES CROSSED ROLLER BEARING

RB series of JCB crossed roller bearing is consisted of an outer ring and an inner ring with a group of cylindrical rollers and spacers (or cages). The rollers are arranged between the inner ring and the outer ring, and spacers are placed between the rollers to prevent them from colliding with each other.

Description

JCB crossed roller bearing (THK series) have six types, including split outer ring type crossed roller bearing with separators(RA),split inner ring type crossed roller bearing with separators(RE),split outer ring type crossed roller bearing with separators(RB),split outer ring type and rotation accuracy achieves the ultra precision ISO Class 2 grade crossed roller bearing with separators(RB…USP),mounting holed type and integrated inner/outer ring  crossed roller bearing with separators(RU),split innerer ring type and rotation accuracy achieves the ultra precision ISO Class 2 grade crossed roller bearing with separators(RE…USP)

_RB series crossed roller bearing is split outer ring type crossed roller bearing with separators

_Outer Diameter of RB series crossed roller bearing is from 36 mm to 1500 mm

_Inner Diameter of RB series crossed roller bearing is from 20 mm to 1250 mm

_Accuracy class of RB series crossed roller bearing: P0,P6,PE6,P5,PE5,P4,PE4,P2,PE2

_Seal Symbol of RB series crossed roller bearing: No symbol signifies the open type without seals.(UU signifies seals on both sides. )

_Axial internal clearance of RB series crossed roller bearing: Including CC0,C0,C1

How to ensure quality of  crossed roller bearing

-Advanced design

From the beginning of design stage, we make a modeling to design crossed roller bearing by advanced design software, then use method of finite element analysis to verify the results.

-Advanced equipment

Base on advanced equipment to ensure product quality, we possess advance processing equipment for key production process, for example, CNC machining center, CNC heat treatment equipment …etc.

-Reliable raw materials

The most important part of ensuring the product quality is raw materials manufacturing, therefore we choose the reliable raw materials to use for element of crossed roller bearing, such as bearing ring and roller etc, we also could provide customize crossed roller bearing with special material.

-Perfect management system

We established perfect management system so to ensure product quality, we passed to certificate ISO9001 quality management system as well as obtain ISO9001 certification, and carry out quality manufacture system strictly for whole process of production from beginning to the end.

-Perfect testing method

We organized a professional and strong testing and inspecting team with advanced test equipment by perfect testing method to guarantee product quality and set up special testing machine and test bed for crossed roller bearing.
