This housing carries a shaft in two bearing seats mounted on a single common base, with a bore diameter d of 32 mm. The body, cover, and grease-guiding disc are made of grey cast iron GG 20. Further dimensions can be read from the catalog drawing: A = 315 mm, D = 90 mm, H = 60 mm, J = 150 mm, L = 190 mm, N = 15 mm, b = 52 mm, w = 53.0 mm, A1 = 255.5 mm, A2 = 214.0 mm, A3 = 331 mm, H1 = 121 mm, H2 = 20 mm, J1 = 225 mm, L1 = 491 mm, L2 = 298 mm, da = 40 mm. Both bearing positions are equipped with grease nipples, and the unit is supplied with seals fitted at both seats. This two-seat, single-shaft arrangement fixes the bearing spacing rigidly through the common base, which the catalog indicates as suitable for fan assemblies. Lubrication is applied directly through the nipples at each seat, and the fitted seals protect both bearing positions from contamination without additional sealing components being required at installation.
