RLS20 is an inch-dimension radial ball bearing, light series, 2-1/2 in bore × 6-1/2 in OD × 1-1/8 in wide (63.5 × 165.1 × 28.57 mm).
The RLS 20 is a ball bearing designed for industrial applications requiring rotational motion support with reduced friction. Ball bearings use spherical rolling elements to maintain separation between bearing races, providing efficient load distribution and smooth operation.
