This spherical roller bearing has two rows of rollers running on a common sphered outer raceway, allowing the outer ring axis to swivel relative to the shaft axis and compensate for misalignment during operation. Bore diameter is 120.0 mm, outside diameter 260.0 mm, and width 86.0 mm, with a net mass of 22.135 kg. The bearing carries a pin-type cage (JPA) and features the E1 design, giving a limiting speed of 2850.0 1/min and a reference speed of 2000.0 1/min. Main dimensions follow DIN 635-2. Radial internal clearance falls within the CN (Group N) range, suitable for standard fits and normal operating temperature conditions. The cylindrical bore (bore type Z) is intended for mounting directly on the shaft without a sleeve. Standard relubrication feature supports periodic grease replenishment during service, and the self-aligning capability of the design permits operation under shaft deflection or housing misalignment without inducing additional internal stress.
