RU SERIES CROSSED ROLLER BEARING

RU 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).

_RU series crossed roller bearing is mounting holed type and integrated inner/outer ring crossed roller bearing with separators

_Outer Diameter of RU series crossed roller bearing is from 70 mm to 540 mm

_Inner Diameter of RU series crossed roller bearing is from 20 mm to 350 mm

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

_Seal Symbol of RU series crossed roller bearing: No symbol signifies the open type without seals.(UU signifies seals on both sides.U signifies seals on one side in the counterbore side of the outer ring.UT signifies seals on one side in the opposite to the counterbore side of the outer ring. )

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