This insert ball bearing carries a spherical outer ring that seats in a matching housing bore, allowing the unit to self-align while the inner ring is fixed to the shaft with grub screws. Bore diameter is 12.0 mm, outside diameter 40.0 mm, width 22.0 mm, and net mass is 0.1 kg. Sealing is executed as NPP, with P-type seals fitted on both sides of the bearing. The grub screw fixation provides a secure, easily mounted connection to the shaft without needing a separate locking collar, while the spherical outer ring compensates for shaft misalignment and housing bore inaccuracy. The NPP sealing arrangement on both faces restricts the ingress of contaminants and retains internal lubricant, making the bearing suited for installation where reliable radial location combined with a sealed running surface is required.
