· The LM guide with ball retainer SRS type has a structure that includes two rolling sides on a compact body, which allows the load to be incurred from all sides, and can be used with a single shaft at locations that have limited space requirements and locations that use moment.
· The adoption of the ball retainer has eliminated mutual friction between the balls, which provides excellent high speed, low noise, good sound quality, long life, and being maintenance-free for long periods of time.
· The ball retainer eliminates the mutual friction between the balls, which improves the grease holdability and reduces the raised dust amount.
· The LM block and LM rail both use stainless steel that are highly rust-proof.
· The rail cross-section height is kept low, and it has a compact structure with a single left and right ball row, which allows it be mounted in space saving areas.
· This is a lightweight type where a part (around the ball escape hole, etc.) of the LM block has been insert formed using resin materials.
