HM — Timken metric-envelope inch-series prefix used on the heavy 6xx families.
624749 — cone number within that family, 4.75 in bore. No precision suffix is present, so the tolerance class is Not specified.
6Y-2546 — the Caterpillar part number carried on this cone. It is a search term a buyer will use, and it identifies the same cone.
Dynamic Load Rating: 362,000 N (C1, one million revolutions). Static Load Rating: 543,000 N. Dynamic radial rating at 90 million revolutions (C90): 93,700 N. Dynamic axial rating at 90 million revolutions (Ca90): 68,500 N. K Factor: 1.37. A K of 1.37 is a steep roller angle for a cone this heavy, so it takes a large thrust share as well as a heavy radial load — the combination found in wheel ends and final drives.
Effective Load Centre: -3.8 mm. Maximum fillet radius on the mating shaft: 3.600 mm (0.140 in). Shaft Backing Shoulder Diameter, frontface (da): 132 mm (5.20 in). Shaft Backing Shoulder Diameter, backface (db): 138 mm (5.43 in). Cage location relative to backface (Aa): 3.3 mm. Cage location relative to frontface (Ab): 3.3 mm. Geometry Factor (Cg): 0.118.
Unit Quantity: 1 Pc. Cone only. Matching cups are the Timken HM624710 and HM624716.
HM624749 is an industry-standard inch tapered roller bearing cone number. Koyo, NTN, NSK and SKF all build an HM624749 to the same boundary dimensions, and all interchange with this cone. Caterpillar 6Y-2546 is the same part under an OEM number.
