JCB CROSSED ROLLER BEARING (HIWIN SERIES)

JCB crossed roller bearing (HIWIN series) is following five types:

CRBA SERIES OF  JCB CROSSED ROLLER BEARING (HIWIN SERIES) CRBA-WW    CRBA-NN

_CRBA is split outer ring type

_Outer Diameter is from 36 mm to 480 mm

_Inner Diameter is from 20 mm to 400 mm

_Accuracy class: P6,P5, P4, P2, D5(PD5),D4(PD4), D2(PD2)

_Seal Symbol: WW signifies seals on both sides. NN signifies the open type without seals. Both types have oil holes for lubrication.

_Axial internal clearance: C1 signifies positive clearance with less friction force, while C8 signifies negative clearance without back lash, which will result in an increase of friction force during unloading conditions.
