This insert ball bearing carries radial load through a wide inner ring that self-aligns within the outer ring, compensating for shaft misalignment. Bore diameter is 45.0 mm, outside diameter 85.0 mm, width 42.9 mm, and net mass is 0.83 kg. Sealing is of the KRR type, integrated on both sides of the bearing. The KRR sealing keeps lubricant in and contaminants out, allowing the bearing to run without frequent maintenance once initially greased. The self-aligning inner ring design suits mounting situations where shaft deflection or housing misalignment must be tolerated without inducing additional stress on the rolling elements. Grease lubrication is standard for this design, and the bearing is suited for mounting via its cylindrical bore in combination with a locking element on the inner ring.
