TimkenTapered Roller Bearing Cup, 11.500 in OD x 1.8125 in Wide, M241500 Inch Series Outer Ring Only

Product Description

What this part is

This is a tapered roller bearing cup — the outer ring on its own, with the tapered raceway ground into its bore. It is the M241510 cup from Timken’s M241500 inch series, measuring 11.500 in (292.100 mm) outside diameter by 1.8125 in (46.038 mm) wide. A cup is one half of a tapered roller bearing; the other half is the cone assembly, which carries the inner ring, the rollers and the cage.

Scope of supply

This listing is the cup alone. Cups and cones are separable components: the cup seats in the housing and the cone seats on the shaft. The mating half of a complete bearing is an M241547 cone or one of its variants.

Decoding the designation

M241510: Timken inch-series cup number. In Timken’s inch numbering the cup and cone are separately numbered within a common series; the M241500 series pairs the M241510 cup with M241542, M241543 and M241547 cones.

The cone number selects the bore. An M241547 cone gives an 8.000 in (203.2 mm) shaft bore. M241542 and M241543 cones give 7.875 in.

30-0295: a distributor and OEM stock number carried on this part, retained as a cross-reference.

Published dimensions and factors

Timken publishes the following against the M241510 cup itself.

Cup Part Number: M241510. Series: M241500 inch series. Outside Diameter (D): 11.5000 in / 292.100 mm. Outer Ring Width (C): 1.8125 in / 46.038 mm. Mass: 26.10 lb / 11.8 kg. e Factor: 0.33. Y Factor: 1.8. Geometry Factor Cg: 0.128. Number Of Rows: 1. Design Units: imperial.

Envelope of the mating half, for a stack-up: with an M241547 cone the bore (d) is 8.0000 in / 203.2 mm and the assembly width (T) is 2.2813 in / 57.945 mm. K Factor for the M241547 / M241510 assembly: 1.76.

What these specs mean in practice

K is the ratio of radial to thrust capability set by the cup angle. A high K means a shallow cup angle and a radially strong, comparatively thrust-weak bearing. At K 1.76 the M241500 series sits at the radial-duty end of the tapered roller range, which is why it appears in heavy off-highway wheel and final-drive positions, large gearbox shafts and mill equipment.

The e Factor of 0.33 is the threshold used in the equivalent-load calculation. Below an axial-to-radial load ratio of 0.33 the thrust component is ignored; above it the load equation changes.

Mounting data

Maximum Housing Fillet Radius: 0.130 in / 3.30 mm. Housing Backing Shoulder Diameter, frontface (Da): 11.02 in / 278.90 mm. Housing Backing Shoulder Diameter, backface (Db): 10.71 in / 272.03 mm. A tapered roller bearing has no built-in internal clearance; the operating clearance or preload is a function of cone-to-cup draw-up at assembly.

Interchange guidance

The M241510 cup number is an industry-standard inch designation and is produced by several manufacturers, so an M241510 from another maker is dimensionally interchangeable. Cross-references: M241510, M-241510, M 241510, 30-0295. Mating cones: M241547 (8.000 in bore), M241542 and M241543 (7.875 in bore). Related assemblies using this cup include the M241547 / M241510 single row and the M241547 / M241510CD double-cup arrangements.

Central Surplus also stocks Caterpillar 240-8240 tapered roller bearing cones and cup-and-cone sets in a comparable large-bore size class.
