This split plummer block unit carries a shaft through two bearing seats mounted on a common housing, designed for a shaft bore diameter (d) of 32 mm. The housing, cap and grease-guiding disc are made of grey cast iron GG 20, with dimension A at 315 mm, D at 90 mm, H at 60 mm, J at 150 mm, L at 190 mm, N at 15 mm, b at 52 mm, w at 53.0 mm, A1 at 255.5 mm, A2 at 214.0 mm, A3 at 331 mm, H1 at 121 mm, H2 at 20 mm, J1 at 225 mm, L1 at 491 mm, L2 at 298 mm, and da at 40 mm — full geometry should be cross-checked against the catalog drawing before installation. 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, which limits contamination ingress along the shaft. The twin-seat housing on a single shaft line suits assemblies where both bearing positions must stay aligned on one supporting frame, as indicated in the manufacturer catalog primarily for fan assembly applications.
