This split plummer block houses two bearing seats on a single shaft line, with the bore diameter (d) sized at 42 mm for shaft fitment. Reading from the catalog drawing, dimension A equals 377 mm, D equals 110 mm, H equals 70 mm, J equals 170 mm, L equals 210 mm, N equals 15 mm, b equals 60 mm, w equals 59.0 mm, A1 equals 311.5 mm, A2 equals 266.0 mm, A3 equals 393 mm, H1 equals 142 mm, H2 equals 25 mm, J1 equals 275 mm, L1 equals 613 mm, L2 equals 360 mm, and da equals 50 mm — these values set the mounting footprint and bolt spacing on the base structure. The housing, cap, and grease-guiding disc are cast from grey cast iron GG 20. Both bearing positions are fitted with grease nipples, allowing lubricant to be replenished at each seat without dismantling the housing. The unit is supplied with seals, which keep contaminants out of the bearing seats during operation. The two-seat layout on a common shaft line is intended for fan assemblies, per the catalog listing for this series.
