NRXT(DD) SERIES CROSSED ROLLER BEARING

NRXT(DD) 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 (NSK series) have two types, including split outer ring type with separator (NRXT…DD),split outer ring type with separator (NRXT…E)…

_NRXT…DD series crossed roller bearing is split outer ring type with separator

_Outer Diameter of NRXT…DD series crossed roller bearing is from 41 mm to 700 mm

_Inner Diameter of NRXT…DD series crossed roller bearing is from 25 mm to 600 mm

_Accuracy class of NRXT…DD series crossed roller bearing: P6,P5, P4, P2

_Seal Symbol of NRXT…DD series crossed roller bearing: No symbol signifies the open type without seals.(DD signifies seals on both sides. E signifies no seal )

_Axial internal clearance of NRXT…DD series crossed roller bearing: Including C8,C1
