GQZ LM20 Linear Ball Bearing 20×32×42mm For Automation Linear Guide Transmission Mechanisms

LM20 is standard cylindrical linear ball bearing. It consists of outer shell, retainer and steel ball circulating assembly. Steel balls circulate along raceways to realize low-friction linear reciprocating motion. Suitable for matched hardened precision ground shaft. Widely applied in automated production equipment, packaging machinery, testing instruments, 3D printers and various linear motion assemblies.

Formal quotation will be sent within 24 hours upon your inquiry.
