The TIMKEN YRM series tapered roller bearing cup is the removable outer race of a tapered roller bearing. It is press-fitted into the housing and forms, together with the cone, an assembly that supports combined radial and axial loads. It is used in applications where significant forces must be transmitted with shafts rotating at moderate speeds, such as gear reducers, road machinery and power transmission equipment.
The YRM series designation is read in parts: the Y indicates that it is a tapered roller cup, the numbers that follow identify the size and geometry of the race, and the suffix RM corresponds to a manufacturing variant. For example, Y30309RM and Y30310RM are cups of the same family, with different outer diameter and width. The complete part number is always assembled with the cup and the cone that corresponds to it; therefore, to request a quote, it is best to provide the exact number that appears on the part or on the drawing.
These cups are used in power transmission equipment, gear reducers, axles of road, agricultural and earthmoving machinery. They also appear in gearboxes, conveyor rollers and machinery for the food and cement industries. In Argentina, they are commonly found in road equipment and in production lines that require replacement with standardized dimensions. MR Accesorios Industriales supplies the TIMKEN brand and can guide you to identify the cup your equipment needs.
To select a YRM cup, take into account the outer diameter and width that the housing must accommodate, and that the cup works with the cone of the same series. Mounting is done with a press or with suitable tools, without striking the race. Lubrication and sealing are key: if the equipment works with dust or moisture, it is advisable to use seals and good quality grease. Alignment between cup and cone prevents point loads and extends bearing life.
Tapered roller cups from different brands can be interchanged if the standardized dimensions and race angle match. It is not enough for the part number to be similar: the outer diameter, width and fillet radius must be verified. In many cases, the TIMKEN YRM cup has an equivalent in other brands, but interchangeability is confirmed with the technical data sheet of the assembly. If you have doubts, send us the part number and housing measurements and we will indicate the compatible alternative.
If you need a TIMKEN YRM series tapered roller cup, write to us on WhatsApp with the complete part number or the equipment model. At MR Accesorios Industriales we will quote you promptly and help you identify the correct part. We can also advise you on the cone that forms the assembly and on mounting care so that the bearing works under optimal conditions.

Frequently Asked Questions
- What is the difference between a tapered roller cup and a cone?
- The cup is the removable outer race and the cone is the inner assembly with the rollers. They are mounted separately and form a complete bearing. To replace, both must be changed or the new cup must be verified as compatible with the existing cone.
- How do I know which TIMKEN YRM cup my equipment needs?
- Look for the part number engraved on the part or on the equipment drawing. If you cannot find it, take the housing measurements: outer diameter and width. With that data we will quote the correct cup or the compatible alternative.
- What care should I take when mounting a tapered roller cup?
- Mount it with a press or puller, without striking the race. Verify that the housing is clean and free of burrs. Lubricate with suitable grease and ensure alignment with the cone to avoid premature wear.
