Frequently Asked Questions
A linear guideway (linear rail with recirculating ball carriages) provides much higher rigidity, load capacity and accuracy than a ball bushing. Linear Guideways from HIWIN are the industry standard for CNC machines, semiconductor equipment and precision automation.
The UR Series Ultra-Heavy Load Roller Linear Guideway is available in accuracy grades from C to H (and ultra-precision UP), with preload classes from light (Z0) to heavy (Z3). We help you select the right combination for stiffness, smoothness and travel accuracy.
Mounting requires a clean, flat reference surface with correct torque on the mounting bolts, and alignment by straightedge or laser. Lubricate the carriage rails regularly with the recommended grease; our Linear Guideways with self-lubricating blocks and wipers reduce maintenance needs.
Linear guideways can run at very high speeds; our QR series silent roller guideways reduce noise and vibration for high-speed applications. The UR Series Ultra-Heavy Load Roller Linear Guideway can achieve high speeds with smooth, quiet motion thanks to optimized ball recirculation.
Yes. We supply Linear Guideways rails cut to your exact length with drilled mounting holes, and carriages preloaded as matched sets for consistent motion and longer service life. OEM/ODM customization is welcome.
Standard models are available in small quantities with shipment within 15 days. Volume and custom orders receive factory-direct pricing — send us the UR Series Ultra-Heavy Load Roller Linear Guideway model, rail length and quantity for a quotation.
