Timken M38510-3 inch tapered roller bearing single cup, Series M38500. The cup is the outer race of a tapered roller bearing. Outside Diameter: 2.6250 in (66.675 mm). Overall Width: 0.6563 in (16.670 mm). Rolling Elements: Tapered Roller. Number Of Rows: 1. Bearing Material: Case-hardened steel. Item Weight: 0.30 kg (0.70 lb). Series: M38500. Base Number: M38510.
M38510 — Series M38500 inch tapered roller cup, unflanged, 2.6250 in outside diameter.
*3 — Precision Class 3: a tighter dimensional tolerance than standard, giving lower running vibration and closer housing location. The same class is written -3, *3 and #3.
e Factor: 0.35. Y Factor: 1.7. Geometry Factor (Cg): 0.068. Precision Class: Class 3. The e and Y factors are the values used to resolve the combined radial and thrust load on the mounted pair: an e of 0.35 sets the axial-to-radial load ratio above which the thrust term governs the equivalent load calculation.
Maximum housing fillet radius cleared by the cup corner: 0.090 in (2.29 mm). Housing backing shoulder diameter, frontface (Da): 2.46 in (62.00 mm). Housing backing shoulder diameter, backface (Db): 2.28 in (57.91 mm). The cup outside diameter is plain and straight, so it seats directly in a bored housing.
Cup only. Unit Quantity: 1 Pc. The matching Timken cones are the M38549, the M38545 and the M38547.
The M38510 cup number is an industry-standard inch designation, so SKF, FAG, NSK, NTN, Koyo, Nachi, PEER and Bower all catalogue an M38510 cup on the same outside diameter, width and cup angle. Those are built to standard tolerance; the *3 marking on this piece is the tighter Class 3 execution. Searchable forms of the number: M38510-3, M38510*3, M38510#3, M-38510, M38510 3 and M385103.
