When a shaft has to carry radial and axial forces at the same time, in both directions, a double row tapered roller bearing is often the answer. TIMKEN builds this type as a complete unit: two rows of tapered rollers held in one frame. Gearboxes, drive shafts and mining machinery are typical homes for it, and MR Industrial Accessories supplies the line along with help picking the right configuration for the mounting.
Reading the code tells you a lot before you open a catalog. Take W-3217-BMachined: the letters and numbers point to the TTHDFL series, an internal identification number, and the BMachined suffix, which means the contact surfaces are machined for a precise fit. Bearings in the TTHDFL series come with a machined cup and cone, which simplifies mounting and spreads the load evenly.
These bearings show up in gear reducers, mills, presses, cranes and railway equipment. Because they take combined loads, they fit positions with high tilting moments, such as the main bearings of rotary tables or rolling mill roll shafts. Food and cement plants also rely on them where the machinery has to hold up under constant work.
Selection starts with the size and direction of the loads, the rotation speed and the surrounding conditions. Sealing matters: in dusty or damp locations, a version with extra seals or retainers is the safer choice. The lubricant has to match the working temperature, and alignment during mounting should be checked so the bearing does not run under parasitic stresses. Internal clearance is another variable to set according to the application.
Equivalents from other brands exist for this bearing type, but they do not always drop in. Tolerances, contact angle and load capacity can differ, so compatibility with the original equipment specifications should be confirmed. We can help you work through those differences, whether the replacement is TIMKEN or another quality brand.

Frequently asked questions
- What does the BMachined suffix mean on a TIMKEN bearing?
- It means the contact surfaces are machined, so the fit is more precise and the load is distributed better. You see it in applications that call for high accuracy and rigidity.
- Does this bearing come with seals or retainers?
- It depends on the part number. Some models have integrated seals; others arrive open so you mount external seals. Send us the exact number and we will confirm.
- Can I replace a bearing from another brand with this TIMKEN one?
- Often you can, but dimensions, tolerances and load capacity need checking first, since not every equivalent is a direct swap. Share the data of the original bearing and we will point you to a compatible option.
