AirTAC LSQH Series Caged Ball Linear Guide – Low-Noise Precision Linear Rail

Specification:

AirTAC LSQH Series Caged Ball Type Linear Guide

The AirTAC LSQH Series is a caged-ball linear guide in which the steel balls are kept at uniform spacing to reduce direct ball-to-ball contact. This structure delivers smoother motion, lower noise and stable performance in high-speed precision applications.

Features

1. Ball-cage design provides low-noise and low-vibration operation.
2. X-shaped rail raceway improves rigidity and multidirectional load capacity.
3. Precision steel balls meet ISO 3290 G10 grade.
4. Integrated overmolded block structure improves strength and sealing.
5. Single-lip oil scrapers clean the rail and help retain lubricant.
6. Double-molded dustproof covers protect the ball circulation system.
7. Single and butt-jointed rail configurations are available.

According to the supplied test charts, the LSQH Series produces lower operating noise than standard ball-type linear guides, especially at higher travel speeds.
