Abstract
A linear motion apparatus has a linear track, a slider and two sliding-assistant units for a linear motion apparatus. The sliding-assistant units for a linear motion apparatus is mounted between the track and the slider to enhance ease of movement between the track and the slider, and each sliding-assistant unit has two roller rings to receive rollers. The roller rings are elongated rectangular rings, are selectively mounted oppositely crossly around each other. Each roller ring is designed with reduced components to make manufacturing and assembling the sliding-assistant unit easier. Moreover, the roller ring is designed as one unity so no seam will be formed due to assembling two different pieces, such that ensures contact between the rollers and the roller ring smooth.
