Provides radial support with a spherical outer ring that seats in a housing bore, allowing angular self-alignment while the shaft connection is made through an adapter sleeve rather than a straight bore. Outside diameter is 90.0 mm, width 34.0 mm, and net mass 0.98 kg. Sealing is provided on both sides by 2RSR seals, protecting the raceway and balls from contamination. The adapter sleeve mounting method allows fitting on plain shafting without a shoulder, and the spherical outer ring compensates for slight misalignment between the housing and the shaft axis. The 2RSR seal arrangement retains internal grease and keeps out dust and moisture, making this insert ball bearing suitable for applications where re-lubrication intervals should be extended and shaft-to-housing alignment cannot be guaranteed with precision.
