GQZ LMS3 Miniature Straight Linear Ball Bushing 3×7×10mm Precision Micro Linear Motion Bearing

LMS3 is miniature straight-type linear ball bushing.

Common variants:

• LMS3:Open type, no seals
• LMS3UU:Double-sided contact rubber seals
• LMS3F:Stainless steel version

It is matched with Φ3mm linear shaft to realize endless reciprocating linear movement. Circumferentially arranged steel balls keep low friction sliding performance. Sealed variant locks internal grease to achieve long maintenance-free running; open version supports regular re-lubrication. Widely used for miniature automated assemblies, optical testing equipment, medical instruments and compact precision machinery with limited installation space.

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