This insert ball bearing transfers radial and axial loads through a spherical outer ring that seats in a housing, with the inner ring secured to the shaft by an eccentric locking collar. Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 42.9 mm, and net mass 0.75 kg. Sealing is provided by T seals fitted on both sides (KTT), designation GE40-XL-KTT-B. The spherical outer ring allows the bearing to self-align in the housing bore, compensating for slight angular misalignment between shaft and housing without inducing additional load on the rolling elements. The eccentric locking collar gives a simple, tool-free method of clamping the inner ring to the shaft, suitable for one-direction shaft rotation. The KTT seals close both sides of the bearing, restricting ingress of dust and moisture into the grease-filled bearing interior and retaining grease lubrication during operation.
