This is a two-bearing housing unit mounted on a common shaft, with the bore diameter d equal to 70 mm. The housing, cover and grease-guiding disc are made of grey cast iron GG 20. The overall dimension A is 556 mm, D is 170 mm, H is 112 mm, J is 260 mm, L is 320 mm, N is 19 mm, b is 80 mm and w is 78.0 mm. Additional layout dimensions A1, A2, A3, H1, H2, J1, L1, L2 and da can be read directly from the drawing on the product card. Both bearing positions are fitted with grease nipples, and the unit is supplied complete with seals. The two-bearing arrangement on a single shaft line allows both support points to be aligned within one rigid cast housing, which simplifies shaft positioning along the length defined by dimension L1. The grease nipples at each bearing position allow relubrication with grease without dismantling the housing, and the supplied seals protect the bearing seats from contamination at the shaft passage marked by diameter da. The cast iron construction of the housing, cover and grease-guiding disc corresponds to the PDNI KPL series as listed in the manufacturer's catalogue.
