The cup is the outer ring of a Timken tapered roller bearing. It is mounted in the housing and forms the raceway for the rollers; together with the cone (inner ring) it completes the bearing. It is used in applications with combined radial and axial loads and where high load capacity is required. MR Accesorios Industriales sells this line.

The designation of these cups combines letters and numbers that identify the size and geometry of the raceway. Codes such as M86611-B, M244210-B, M249710-B and M249711-B follow a system where the letter M and the numeric series define dimensions and angles. The -B suffix indicates a construction variant within the family. To select the correct cup, the code must be matched with the corresponding cone, since both form a set and are not interchangeable with each other.

These cups are used in power transmission equipment, gearboxes, axles of road construction, agricultural and railway machinery, and generally in any assembly that must withstand simultaneous radial and axial loads. In Argentina we see them in mills, conveyor belts, presses and machinery for the food and cement industries. Their tapered roller design allows them to tolerate slight misalignment and operate at moderate speeds with good rigidity.

For mounting, verify that the housing has the appropriate tolerance and surface finish for a tapered roller cup. Lubrication must be consistent: grease or oil depending on the operating conditions, with periodic renewal. Axial clearance is adjusted through the cone or shims; excessive clearance generates noise and wear, and insufficient clearance raises the temperature. Alignment between cup and cone is critical to avoid point loads on the rollers.

Timken is a world reference in tapered roller bearings, and there are equivalents from other brands that manufacture under similar standards. Interchangeability is not automatic: dimensions, raceway angle and load capacity must be compared. At MR Accesorios Industriales we advise you to find the Timken cup that best suits your equipment, always with the exact designation.
