CRBFV SERIES CROSSED ROLLER BEARING

CRBFV 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).

_CRBFV…A series crossed roller bearing is mounting holed type high rigidity crossed roller bearing V with separator

_Outer Diameter of CRBFV series crossed roller bearing is from 52 mm to 240 mm

_Inner Diameter of CRBFV series crossed roller bearing is from 10 mm to 115 mm

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

_Seal Symbol of CRBFV 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 CRBFV series crossed roller bearing: Including T1,C1,C2
