CRBH SERIES CROSSED ROLLER BEARING

CRBH 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 (IKO series) have eleven types, split outer ring type Full complement (CRB), split outer ring type with cage (CRBC), Mounting Holed Type High Rigidity With Separator (CRBF), Mounting Holed Type High Rigidity With Separator (CRBFV),High Rigidity Type With Separator (CRBH),High Rigidity Type With Separator (CRBHV),Slim Type With cage (CRBS),Slim Type With separator (CRBS…A), Slim Type Full complement (CRBS…V),Super Slim Type With separator (CRBT),Mounting Holed Type Super Slim Type With separator (CRBTF).

_CRBH…A series crossed roller bearing is high rigidity type crossed roller bearing with separator

_Outer Diameter of CRBH series crossed roller bearing is from 36 mm to 360 mm

_Inner Diameter of CRBH series crossed roller bearing is from 20 mm to 300 mm

_Accuracy class of CRBH series crossed roller bearing: P6,P5, P4, P2

_Seal Symbol of CRBH series crossed roller bearing: No symbol signifies the open type without seals.( UU signifies seals on both sides. U signifies seal on one side.UD signifies seal on one side in the opposite direction to counter bored mounting holes on outer ring.)

_Axial internal clearance of CRBH series crossed roller bearing: Including T1,C1,C2

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.
