CRBT 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.


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).

_CRBT…A series crossed roller bearing is super slim type crossed roller bearing with separator

_Outer Diameter of CRBT series crossed roller bearing is from 21 mm to 61 mm

_Inner Diameter of CRBT series crossed roller bearing is from 10 mm to 50 mm

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

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