This housing unit accommodates a shaft of 38 mm bore diameter (d) and provides two bearing seats on a common shaft within a single cast body. The housing, cover, and grease-guiding plate are made of grey cast iron GG 20. Key dimensions read from the catalogue drawing include D = 100 mm, H = 70 mm, J = 170 mm, L = 210 mm, N = 15 mm, b = 52 mm, w = 63.0 mm, A = 360 mm, A1 = 279.5 mm, A2 = 236.0 mm, A3 = 376 mm, H1 = 137 mm, H2 = 22 mm, J1 = 250 mm, L1 = 536 mm, L2 = 340 mm, and da = 45 mm. Both bearing positions are fitted with grease nipples, allowing relubrication without dismantling the housing, and the unit is supplied with seals fitted at both bearing seats. The twin-seat design on one shaft line, combined with the grey cast iron construction of the housing, cover, and grease-guiding plate, suits applications requiring two aligned bearing positions supported in a single rigid body, primarily intended for fan assembly configurations as indicated in the manufacturer's catalogue.
