Detailed Product Description
Anti Friction Caged Linear Roller NTN Bearing Cylindrical NF 421 NF 202
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
