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, together with the cone, forms 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 gearboxes, road construction 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 RM suffix corresponds to a manufacturing variant. For example, Y30309RM and Y30310RM are cups from the same family, with different outside diameter and width. The complete part number is always made up of the cup and its matching cone; therefore, to request a quote, it is best to provide the exact number marked on the part or on the drawing.

These cups are used in power transmission equipment, gearboxes, shafts of road construction, agricultural and earthmoving machinery. They also appear in gear cases, conveyor rollers and machinery for the food and cement industries. In Argentina, they are commonly found in road construction equipment and in production lines that require replacement with standardized dimensions. MR Accesorios Industriales sells the TIMKEN brand and can help you identify the cup your equipment needs.

To select a YRM cup, take into account the outside diameter and the 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 operates with dust or moisture, it is best 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 the race angle match. It is not enough for the part number to be similar: the outside 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 the housing dimensions and we will indicate the compatible alternative.

We can also advise you on the cone that forms the assembly and on mounting care so that the bearing operates under optimal conditions.
