Description
TIMKEN A6157-B 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 A6157-B and any equivalents.
In a tapered roller bearing, the cup is the outer ring that seats in the housing. Paired with the cone, the inner ring that carries the rollers, it makes up a unit built to take radial and axial forces at the same time. You will find this arrangement in gearboxes, wheel hubs, farm equipment and other machinery where fit and load capacity matter.
Reading the reference is the first step. Take A2126-B, A4138-B and A6157-B: the leading A marks the cup family, the digits set the size, and the -B ending points to a particular construction inside that family. Each full reference locks in one outside diameter and one width, so the cup has to line up with both the cone and the housing bore. Quoting the complete number avoids mismatches.
These parts suit assemblies that carry combined loads and are adjusted separately. Typical homes for them include gear cases, hubs on highway and agricultural equipment, machine tools, process pumps and conveyors. Buyers in metalworking, agriculture and mining rely on this tapered roller line for that kind of duty.
Selection usually starts from the cone already on the shaft, or from the complete bearing number. Cup and cone are matched as a pair, so replacing one means checking the other. Installation calls for a press or controlled heating, never a direct blow on the raceway. Grease or oil rated for the working temperature, plus proper housing sealing, largely decide how long the bearing lasts; axial clearance should follow the equipment manual.
TIMKEN nomenclature cross-references with other makers, but the match is normally made on dimensions such as outside diameter, width and raceway angle rather than on the number itself. Replacing a cup from a different brand? Send the measurements or the original reference and we will point you to the equivalent in the TIMKEN line we carry.
For a quote, message the full part number to MR Industrial Accessories on WhatsApp or by email. If the designation is unclear or you need a variant you cannot find, send the model or the measurements and our team will answer promptly, including guidance on the matching cone and mounting criteria.

Frequently asked questions
- How do I identify the cup I need?
- Use the complete part number marked on the cup or on the original bearing. Without it, send the outside diameter, the width and the cone you plan to use, and we will give you the corresponding TIMKEN reference.
- Is the cup sold alone or with the cone?
- It can be quoted on its own, but cup and cone must always be confirmed as a correct pair. Both parts form the assembly and do not interchange between series. If you have both numbers, send them.
- What care does mounting require?
- Seat the cup in the housing with a press or even heating, without hitting the raceway. Then set axial clearance as the equipment requires and lubricate with the specified product. Misalignment shortens bearing life.
