This split plummer block houses two bearing seats on a single shaft line, supporting a bore diameter d of 80 mm. The housing, cap and grease-guiding disc are cast from grey iron GG 20. Overall footprint dimension A is 605 mm, with D at 190 mm, H at 112 mm and J at 290 mm; the mounting dimension L is 350 mm and N is 19 mm. Further reference dimensions from the drawing are: b = 85 mm, w = 82.5 mm, A1 = 510.0 mm, A2 = 446.5 mm, A3 = 625 mm, H1 = 230 mm, H2 = 30 mm, J1 = 460 mm, L1 = 965 mm, L2 = 575 mm, and da = 90 mm — these can be cross-checked against the dimensional drawing on the product card. Both bearing positions are fitted with grease nipples, allowing relubrication without dismantling the housing, and the unit is supplied complete with seals fitted at both bearing positions. The two-seat arrangement on a common shaft keeps both bearing locations aligned within the housing structure, which is the configuration the manufacturer's catalogue lists primarily for fan assemblies.
