SMA heavy load linear guides provide smooth, precise motion for machinery requiring high rigidity and reliable load support. Ball raceways with a 45° contact angle provide equal load capacity in radial, reverse radial, and lateral directions, allowing installation in any orientation.

Balanced preload increases rigidity in all four directions while maintaining low frictional resistance. The lubrication system distributes lubricant evenly throughout each ball circulation loop, supporting running accuracy, long service life, and reliable operation.

SMA linear guide rails and carriages combine a compact design with self-alignment capability, quiet movement, and interchangeability.

Key Features

• Equal load capacity in four directions — supports flexible mounting arrangements.

• High rigidity — balanced preload supports precise linear movement under load.

• Self-alignment capability — accommodates minor alignment deviations.

• Smooth, quiet motion — low frictional resistance ensures consistent travel.

• Interchangeability — simplifies component selection and replacement.
