Timken 52400W/52637B is an inch single-row tapered roller bearing with a flanged cup (TSF type) from the Timken 52000 series: a 52400W cone with a 52637B single flanged cup. Bore Diameter: 4.0000 in (101.600 mm). Outside Diameter: 6.3750 in (161.925 mm). Flange Outer Diameter: 6.6210 in (168.173 mm). Condition: new old stock, made in USA, with surface staining.
52400W — Timken cone, 4 in bore, W execution of the 52400 cone.
52637B — Timken single cup, 6-3/8 in outside diameter. The B suffix on a cup marks a flanged cup; the flange locates the cup axially in a through-bored housing.
Dynamic Load Rating (C1): 223,000 N (50,200 lbf). Dynamic Load Rating (C90): 57,900 N (13,000 lbf). Static Load Rating (C0): 343,000 N (77,000 lbf). Dynamic Thrust Rating (Ca90): 47,100 N (10,600 lbf). A single-row tapered roller bearing takes combined radial and one-direction thrust load and is normally mounted opposed to a second bearing.
Cone Width: 1.4219 in (36.116 mm). Cup Width: 1.0313 in (26.195 mm). Cup Flange Width: 0.25 in (6.35 mm). Series: 52000. Rolling Elements: Tapered Roller. Number Of Rows: 1. Closure Type: Open.
