Timken 52375-3 tapered roller bearing cone: the inner ring with its roller and cage assembly. Bore 3.7500 in (95.250 mm), inner ring width 1.4219 in (36.116 mm), stamped steel cage, case-carburized steel. The matching cup is the Timken 52618.
52375 is the cone number in the Timken 52000 imperial series. The suffix marked on the carton as 52375 #3 is Timken precision Class 3, which holds tighter bore and running accuracy tolerances than standard Class 4 product.
The figures below are cone values. K factor is 1.23, the ratio of radial to thrust capability, and at that value this is a comparatively steep taper with strong thrust capability: dynamic axial rating is 10,600 lbf against a dynamic radial rating of 13,000 lbf on the Timken ninety-million-revolution basis. Dynamic radial rating on the ISO one-million-revolution basis is 50,200 lbf and static radial rating is 77,000 lbf. Effective centre location is –0.02 in, just inside the cone backface.
Cone only, one piece. The matching cup is the Timken 52618, with the 52618P as a second cup variant. Cone weight 16.73 lb.
Shaft backing shoulder diameter is 4.13 in at the frontface and 4.41 in at the backface. Maximum shaft fillet radius that the cone corners clear is 0.14 in. Cage location relative to the backface is 0.16 in and relative to the frontface 0.12 in.
Tapered roller bearings mount in opposing pairs, and the setting is established at assembly by adjusting the axial position of one row against the other. The lubrication life adjustment geometry factor Cg is 0.152, with G1 of 175.4 and G2 of 41.7.
The 52375 cone runs against the 52618 cup, and against the 52618P where that cup variant is specified. The complete assembly designation is 52375/52618.
