DRIVE UNIT INCORPORATED LINEAR MOTION GUIDE ASSEMBLY

摘要

A small-sized linear motion guide assembly includes a bed having a U-shaped cross section, a sliding table having a U-shaped cross section and a plurality of rolling members interposed between the bed and the sliding table to thereby provide a relative motion between the bed and the sliding table. A drive pulley is provided at one end of the bed and an idle pulley is provided at the other end with an endless timing belt extended between the drive and idle pulleys. The drive pulley is operatively coupled to a stepping motor so that when the motor is driven, the sliding table is caused to move relative to the bed.
