The bore diameter d is 90 mm, and the seat diameter da measures 100 mm. Overall mounting dimensions from the catalog drawing include A = 673 mm, A1 = 570.0 mm, A2 = 500.0 mm, A3 = 693 mm, D = 215 mm, H = 130 mm, H1 = 264 mm, H2 = 40 mm, J = 320 mm, J1 = 500 mm, L = 400 mm, L1 = 1033 mm, L2 = 635 mm, N = 24, b = 95 mm, and w = 96.5 mm — refer to the catalog drawing for exact placement of each dimension on the housing. Both bearing positions are fitted with grease nipples, allowing separate lubrication of each seat without disassembly. The housing is supplied with seals, which protect the bearing seats from contamination during operation. According to the manufacturer catalog, this housing series is indicated primarily for fan assembly shaft lines, where the two-seat single-shaft layout supports both bearing positions along a common axis.
