Grooved Roller (Stainless Steel 304) — Smooth, Quiet, Durable Key benefits Reliable material: Made from stainless steel 304 for good mechanical strength, corrosion resistance, and long service life. Quiet, smooth operation: Precisely made grooved rollers glide smoothly along guide rails to reduce vibration and operating noise. Flexible alignment: The universal head rotates 360° to accommodate a wide range of surface orientations and installation angles. Multiple specifications: Available in six standard types to match different guide profiles and load needs: 48 U-Type, 48 V-Type, 48 H-Type, 68 U-Type, 68 V-Type, 68 H-Type. What this product solves Reduces wear and maintenance by using durable 304 stainless steel and precision machining that ensures consistent rolling contact. Lowers operational noise in sliding systems by enabling smooth, vibration-free motion on guide rails. Simplifies alignment and installation in applications with changing angles thanks to the 360° rotatable universal head. Features and compatibility Material: Stainless steel 304 — good mechanical properties and corrosion resistance for indoor and many outdoor uses. Function: Grooved roller designed to run on guide rails; minimizes noise and enables steady motion. Models: 48 U-Type, 48 V-Type, 48 H-Type, 68 U-Type, 68 V-Type, 68 H-Type to suit different rail profiles and load conditions. Performance: Precision manufacturing for quiet, low-friction operation and extended service life. Practical use scenarios Sliding doors and gates: Durable, quiet rolling for residential or commercial sliding door systems that run on guide rails. Conveyor or guide systems in light industrial settings: Consistent motion and reduced noise for material handling or positioning tracks. Adjustable fixtures and movable partitions: 360° rotatable head allows the roller to conform to varying surface angles and mounting orientations. Specifications summary Material: Stainless steel 304 Available types: 48 U-Type, 48 V-Type, 48 H-Type, 68 U-Type, 68 V-Type, 68 H-Type Key functions: Smooth glide on guide rails, noise reduction, 360° universal head rotation Choose the appropriate type (48 or 68, U/V/H) based on your guide rail profile and load requirements to ensure reliable, quiet operation.
