Timken 71450W tapered roller bearing cone assembly — the inner race complete with its rollers and cage. Brand: Timken. Designation: 71450W. Base Number: 71450. Series: 71000 inch tapered. Bearing Type: tapered roller bearing, cone assembly. Bore: 4.500 in (114.3 mm). Design Units: English. Number Of Rows: 1. Rolling Elements: tapered rollers. Unit Quantity: 1 Pc. Cone only. The matching cup is the Timken 71750.
71450: the ANSI/ABMA cone number in Timken’s 71000 inch tapered series. W: a Timken variant marking carried on this item, retained as a search term. Listing search forms: 71450W, 71450, 71450 W.
The load rating of a tapered roller bearing is a property of the assembled cone and cup. Timken publishes the following for the complete 71450/71750 tapered single assembly. Bore d: 4.500 in (114.3 mm). Outside Diameter D: 7.500 in (190.5 mm). Overall assembled width T: 1.875 in (47.625 mm). Cone width through bore B: 1.9375 in. Cup width C: 1.375 in. Dynamic Load Rating (C1): 364,000 N. Static Load Rating (C0): 543,000 N. Assembly weight: approximately 5.2 kg.
The cone is wider than the assembled bearing — 1.9375 in against 1.875 in — because the cone’s back face projects past the cup when the rollers are seated. Tapered roller bearings are adjustable, so the running clearance or preload of the assembly is set at fitting rather than built into the components.
Unit Quantity: 1 Pc. The sale unit is one cone assembly: inner race, tapered rollers and cage. The matching cup is the Timken 71750.
71450 is an industry-standard inch tapered cone number available from several manufacturers, and same-number substitution is generally valid on geometry. The mating cup is 71750, with a flanged variant 71750-B for TSF (tapered single with flange) arrangements. The 71425 cone runs against the same 71750 cup at a smaller bore, so the cone number identifies a used assembly more reliably than the cup number.
