Description
TIMKEN H239612 belongs to tapered roller bearing cup, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for H239612 and any equivalents.
In a tapered roller bearing, the cup is the outer ring. Its tapered raceway sits in the housing and pairs with the cone, the inner ring that carries the rollers and cage. Together they take combined radial and axial loads, which is why this arrangement shows up in gearboxes, wheel axles, lifting equipment and transmission drives.
Reading the code helps you order the right part. This series opens with the letter H, then a numeric block that sets the size and design of the cup. Compare H238110, H239610, H242610 and H247510: the digits change the outer diameter and the raceway width. Suffixes, where they appear, point to variants in tolerance, angle or treatment. That is why the full part number matters when you request a quote.
On the shop floor these cups turn up in gearboxes, heavy vehicle axles and hubs, mills, conveyor belts, presses and road equipment. Agricultural machinery is another common spot, since a tapered roller setup handles slight misalignment and impact loads. Because the cup is a wear part, it is normally ordered alongside its matching cone so the original torque is kept and early failures are avoided.
Selection comes down to the outer diameter and width of the cup, the contact angle and how the assembly is sealed. Fitting is done in the housing with a press or controlled heating, never by hitting the raceway. Use a lubricant suited to the speed and temperature, and keep cup and cone aligned so the rollers run without loaded edges.
TIMKEN tapered rollers follow widely used size standards. Interchange between manufacturers exists for many series, but it is not automatic: tolerances, angles and radii differ. If you are replacing a cup, send the original part number and we will point you to a compatible option or quote it to your requirements.
Have the cup number, the cone number or the housing size at hand? Send it over on WhatsApp. We will quote promptly and help you match the cup and cone as a set. We can also review applications with combined loads or demanding speeds and advise on installation and lubrication.

Frequently asked questions
- How does the cup differ from the cone in a tapered bearing?
- The cup is the outer ring with the tapered raceway and fits into the housing. The cone is the inner ring holding the rollers and cage, mounted on the shaft. The two are replaced as a pair so clearance and contact stay correct.
- How do I identify the TIMKEN cup my equipment needs?
- Give us the part number marked on the old cup, the cone number or the housing dimensions. With that we can quote the equivalent cup and confirm it matches the cone you already have.
- What should I watch for when installing a tapered roller cup?
- Fit it with a press or gentle heating and avoid striking the raceway. Confirm alignment with the cone, lubricate for the working speed and set the axial clearance the equipment manufacturer calls for to prevent overloads.
