This deep groove ball bearing carries a cylindrical outer ring and an inner ring sized for a fit connection, with a bore of 13.0 mm, an outside diameter of 40.0 mm and a width of 18.3 mm. Net mass is 0.09 kg. Sealing on both sides is provided by R-type seals (KRR), keeping contaminants out and retaining grease within the bearing. The cylindrical outer ring allows mounting into a housing without additional axial location features, while the inner ring designed for a fit connection supports secure clamping onto the shaft. Double-side sealing makes the bearing suited for grease lubrication without the need for external protection, and the compact width-to-diameter proportions keep the design suitable for applications where limited axial space is available alongside standard radial load support.
