Smooth-Roll U-Shaped Sliding Roller

Dimensions: 30 mm outer diameter, 6 mm inner hole, 3.8 mm groove base, 10 mm thickness. Net weight ~10 g. Core component is grade 66 bearing steel — selected for hardness, fatigue resistance, and corrosion tolerance — encased in a black nylon wheel for friction control and noise suppression. The U-shaped profile delivers directional stability and track conformity, particularly beneficial in narrow or shallow grooves found in modern slimline sliding systems. Designed for ease of integration into existing UK-certified building hardware ecosystems.
