Timken 52375-3 inch tapered roller bearing cone. Bearing Type: Tapered roller bearing cone — the inner ring carrying the tapered rollers and cage as one assembly. Series: 523. Base Number: 52375. Bore Diameter: 3.7500 in (95.250 mm). Overall Width: 1.4219 in (36.116 mm). Bore Type: Straight. Rolling Elements: Tapered Roller. Number Of Rows: 1. Item Weight: 7.587 kg (16.73 lb).
52375 — Timken base cone number in the 523 inch series, 3.7500 in bore.
*3 — Timken Precision Class 3. Tighter running and mounting tolerance than standard class, giving lower running vibration and closer shaft location. The same class is written 52375-3, 52375 *3 and 52375 #3.
Dynamic Load Rating: 223,000 N (C1, one million revolutions). Static Load Rating: 343,000 N. Dynamic radial rating at 90 million revolutions (C90): 57,900 N. Dynamic axial rating at 90 million revolutions (Ca90): 47,100 N. K Factor: 1.23. A K factor near 1.2 puts the roller angle in the medium range, so the cone carries heavy radial load while still taking a useful thrust component in an opposed pair.
Effective Load Centre: -0.5 mm. Maximum fillet radius on the mating shaft: 3.600 mm (0.140 in). Shaft Backing Shoulder Diameter, frontface (da): 105 mm (4.13 in). Shaft Backing Shoulder Diameter, backface (db): 112 mm (4.41 in). Cage location relative to backface (Aa): 4.1 mm. Cage location relative to frontface (Ab): 3 mm. G1 Factor: 175.4. G2 Factor: 41.7. Geometry Factor (Cg): 0.152.
Unit Quantity: 1 Pc. Cone only. The matching cups are the Timken 52618 and 52618P.
52375 is an industry-standard inch tapered roller bearing cone number. Koyo, NTN, NSK, SKF and BCA/Bower all build a 52375 to the same boundary dimensions, and all interchange with this cone. Precision Class 3 is a Timken tolerance grade; a standard-class 52375 from any maker fits the same envelope but holds a wider tolerance band.
