High-Precision Roller Linear Guides for Industrial Applications
Our roller linear guide series uses cylindrical rollers instead of balls to support heavy loads and provide smooth linear motion. With linear contact between the rollers and the guide rail, only minimal elastic deformation occurs even under high loads. The 45-degree contact angle design further enhances the guide's ultra-high rigidity and heavy load capacity.
Compared with ball-type linear guides, linear roller guides are the ideal choice for high-speed automation systems and equipment that demand high rigidity and precision.
How Do Our Roller Linear Guides Ensure Precision and High Load Capacity
High Rigidity and High
Precision
Our roller-type rolling elements use a line contact mechanism to minimize elastic deformation under heavy loads, delivering exceptional guideway rigidity. This design maintains precise motion even under demanding conditions, ensuring reliable performance for industrial equipment.
Structural Optimization
The reflow module allows rollers to circulate smoothly and continuously, reducing friction and wear. Finite element–optimized slider and guide rail structures ensure even load distribution, thereby prolonging service life.
Optimized Load Capacity
and Size
The DB (45°-45°) contact angle design allows rollers to support both vertical and horizontal loads simultaneously. This enables a more compact guide rail design while maintaining the same load capacity, helping to miniaturize equipment and save installation space.
Versatile Mounting
The HRW series features a flanged slider with bottom-lock installation, offering low assembly height and a large bearing area for torque-load applications. In contrast, the HRL series has a narrow slider with top screw holes, ideal for space-constrained equipment and quick installation.
