PRODUCT DETAILS

LM series is the most widely used standard linear bearing series for linear motion systems. These bearings feature a steel cage with multiple recirculating ball circuits to ensure smooth, low-friction axial movement and good radial load capacity.
 
Available in standard closed (UU) type, they support high-speed linear operation and allow certain angular misalignment. Standard metric dimensions ensure high interchangeability with global linear shaft and housing systems, making them ideal for automation equipment, precision instruments and small industrial machinery.
