A tapered roller cone is the inner half of the bearing: raceway, rollers and cage in one unit. It only works as a pair, so it is matched to a cup carrying the same basic number. TIMKEN's JHM family covers duties where radial and axial forces arrive together, including transmission cases, gearboxes and earthmoving machinery.
Every code in this family opens with the JHM prefix, and the digits that follow form the basic number. JHM33449, JHM88540, JHM318448, JHM516849, JHM534149, JHM720249, JHM807045 and JHM840449 all follow that pattern. Because cone and cup are ordered as separate pieces and then assembled into a set, the code you read off the component or the machine manual is what identifies your part.
Speed reducers, gearboxes, roller shafts, rotary kilns, conveyor belts and road equipment are common homes for these cones, alongside metallurgy, cement, mining and food processing plants. The same bearings appear in seeders and combine harvesters, where combined loads and tough conditions call for a robust bearing and a controlled maintenance routine.
Selection comes down to the radial and axial load, the rotating speed and the lubrication method. Fitting calls for clean surroundings, correct alignment and a preload or axial clearance set to what the equipment specifies. Sealing and lubrication done properly are what keep the bearing in service. When swapping out a bearing, confirm both the basic number and its matching cup, or send the code and shaft dimensions our way.
Dimensional standards make tapered roller bearings interchangeable across brands, so a TIMKEN cone can give way to an equivalent from another maker when basic number, dimensions and contact angle line up. Codes are not freely mixed, though: a cup only pairs with the cone sharing its basic number. Ask us and we will point you to a compatible option.

Frequently asked questions
- How do the cone and the cup of a tapered roller bearing differ?
- The cone carries the inner raceway together with the rollers and the cage, while the cup is the outer ring. Each is mounted on its own and then brought together as one assembly, which is why the shared basic number is what you need when ordering. Send the full code and both parts can be quoted.
- Where do I find the basic number on my TIMKEN bearing?
- It is marked on the cone and on the cup. In the JHM series the code begins with JHM and continues with digits. Pass that code to us on WhatsApp and we will quote the cone on its own or the complete assembly.
- Can TIMKEN bearings be swapped for other brands?
- They can, as long as the usual dimensional standards are respected. A TIMKEN cone may be replaced by another brand's equivalent when the basic number, dimensions and contact angle agree. Share the code with us and we will confirm a compatible alternative.
