The cup is the outer ring of a Timken TSF tapered roller bearing. It seats in the housing and provides the raceway for the rollers; paired with the cone (inner ring), it completes the bearing assembly. This component suits applications that combine radial and axial loads and require high load capacity.
Cup designations use letters and numbers to indicate raceway size and geometry. Examples include M86611-B, M244210-B, M249710-B, and M249711-B. In these codes, the letter M and the numeric series define dimensions and angles, while the -B suffix denotes a construction variant within the family. Always match the cup code with its corresponding cone; the two parts form a set and are not interchangeable.
Typical uses cover power transmission equipment, gearboxes, axles of road construction, agricultural and railway machinery, and any assembly that must handle simultaneous radial and axial loads. The tapered roller design tolerates slight misalignment and operates at moderate speeds with good rigidity.
During mounting, confirm the housing has the correct tolerance and surface finish for a tapered roller cup. Lubrication—grease or oil depending on operating conditions—must be consistent and renewed periodically. Adjust axial clearance through the cone or shims: too much clearance causes noise and wear, while too little raises temperature. Proper alignment between cup and cone is critical to prevent point loads on the rollers.
Timken is a well-known name in tapered roller bearings, and other brands offer equivalents built to similar standards. Interchangeability is not automatic: compare dimensions, raceway angle, and load capacity. At MR Industrial Accessories, we help you find the Timken cup that fits your equipment, always using the exact designation.
To request a cup, send the code on WhatsApp or email: M86611-B, M244210-B, M249710-B, M249711-B, or the one shown on your equipment. We will reply promptly with a quote and point you to the best solution for your application.

Frequently asked questions
- What is the difference between a cup and a cone in a tapered roller bearing?
- The cup is the outer ring that mounts in the housing; the cone is the inner ring with rollers and cage. Both form the complete bearing and must share the same series number to work correctly. They are not interchangeable with each other.
- How do I identify the Timken cup my equipment needs?
- Check the code engraved on the cup or the old cone. If it is not visible, send us a photo or the housing measurements on WhatsApp and we will help you identify the exact reference or an equivalent.
- Are there equivalents from other brands for these cups?
- Yes, other brands make tapered roller bearings with similar dimensions. Interchangeability is not automatic: outer diameter, width, and raceway angle must be compared. We can indicate a compatible alternative for your application.
