THK MST Miniature Stroke
The THK MST Miniature Stroke is designed for smooth and accurate linear motion in compact equipment. It consists of an ST shaft, ball cage and nut. These parts can be combined to suit the application.
The MST uses 1 mm precision steel balls in a copper alloy ball cage. Its small design saves space, while the point contact between the balls and raceways provides low friction. The bearing is also designed for long-term use with high durability.
The THK MST Miniature Stroke is available with 3 to 6 mm shaft diameters. Permissible loads range from 68.6 to 216 N, depending on the configuration. It is suitable for precision measuring equipment, optical instruments, OA equipment and other compact applications.
