RA SERIES CROSSED ROLLER BEARING

RA 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).

1、_RA series crossed roller bearing is split outer ring type crossed roller bearing with separators

2、_RA…C series crossed roller bearing is split outer ring type crossed roller bearing with separators, outer ring also has high rigidity due to a single-split

3、_RAU series crossed roller bearing is the extremely small crossed-sectional area allows it to be used in lightweight, compact devices. The integrated inner/outer ring structure can be used for both inner and outer ring rotation. There is a 5 mm thin type and an RA interchangeable type.

_Outer Diameter of RA series crossed roller bearing is from 66 mm to 226 mm

_Inner Diameter of RA series crossed roller bearing is from 50 mm to 200 mm

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

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

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