This detailed engineering drawing depicts roller components for a coke pusher car used in steel manufacturing. The assembly consists of 16 distinct items including an 8-roller system with accompanying hardware. Key components include 150mm diameter rollers, 73mm diameter shafts made from C-45 steel, thrust washers, packers, covers, and spacers. The drawing features multiple section views (C-C, D-D, E-E, F-F) showing critical interfaces between components, with precisely specified tolerances for bearing fits (P7/g6). The roller assembly includes SKF-6010-2RS bearings and felt seals (SKF-FS-260), with mounting hardware consisting of socket head cap screws (M6×25, M6×18), hex bolts (M16×60), nuts, and spring washers. According to the bill of materials, each, essentially, car requires two complete assemblies with a total weight of 244 kg (122 kg per assembly). The document follows IS:2102 Class ‘m’ tolerancing standards and IS:3073:1967 surface roughness specifications, with all parts requiring clear identification markings per the drawing notes.
