Detailed Product Description
Linear Industrial Cylindrical Roller NTN Bearing NJ218 E / NJ430 / NJ2308 E
Introduction
Linear bearing often cooperate with quenching line transmission shaft when using.It is a systerm doing strait line moving.Due to the point contact between loading ball bearing and quenching transmission shaft, Linear bearing has low loading capacity.But Linear bearing is with smallest friction , high precision and fast moving speed when they doing linear motion
