This deep groove ball bearing compensates for shaft misalignment through a spherical outer ring surface that seats in a matching housing bore, while the inner ring is machined for a standard fit. Main dimensions are 50.0 mm bore, 90.0 mm outside diameter and 20.0 mm width, with a net mass of 0.43 kg. Both sides are closed with R seals (NPP sealing), keeping lubricant in and contaminants out. The spherical outer ring allows the bearing to accommodate angular deviation between shaft and housing without generating additional load on the rolling elements, which is useful where perfect alignment cannot be guaranteed during mounting. The double-side sealing makes the bearing suitable for grease lubrication and reduces the need for maintenance once installed, as relubrication intervals can be extended due to the protected internal space.
