Description
NSK M 86610 is a reference of tapered roller bearing cup, within Bearings. Request a quote for M 86610 via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.
The cup is the removable outer ring of a tapered roller bearing. It is mounted in the housing and forms the raceway for the rollers together with the cone, which goes on the shaft. This NSK part is sourced by part number: you send the number shown on the part or on the drawing and MR Accesorios Industriales quotes the exact cup. It is used in wheel hubs, gearboxes, road construction machinery and industrial equipment working under combined loads.
The designation of this line is read as the letter M followed by a five- or six-digit number. In the examples M 84210, M 84510, M 86610 and M 236810, the M identifies the cup series and the number defines the geometry: outer diameter, width and raceway angle. Since the cup and the cone are selected as a set, the cup part number alone is not enough to define the complete bearing: the original combination must be respected or the equivalence checked against the complete part number.
In Argentine industry, these cups appear in wheel hubs of trucks and trailers, in transmission gearboxes, in speed reducers, in road construction machinery and in milling equipment. They are also replaced in milling machine spindles and in heavy conveyor rollers. As a wear part, the cup is replaced together with the cone when there is pitting, wear or axial play out of tolerance.
For a correct selection, take axial play into account: it is adjusted with the cone, not with the cup. Check that the housing is clean, free of burrs and with the correct concentricity. The cup is mounted with a press or a suitable tool, never by striking the raceway. Lubrication and sealing are selected according to the environment: grease for low speed, oil for closed gearboxes, and seals that prevent the ingress of dust and water.
Tapered roller bearing cups are interchangeable between brands by part number and by standardized dimensions. If the customer brings a part number from another brand, the equivalence can be found by outer diameter, width and angle measurements. The interchangeability is always confirmed with the complete bearing part number.
If you need a cup from this series, send the part number by WhatsApp to MR Accesorios Industriales. We will quote it shortly. If you have the assembled bearing, also send the cone part number to verify the combination. At MR we source the part you need.

Frequently Asked Questions
- What is the difference between the cup and the cone of a tapered roller bearing?
- The cup is the removable outer ring and the cone is the inner ring with the rollers. They are mounted separately: the cup in the housing and the cone on the shaft. To replace the bearing, both are changed, respecting the complete part number.
- How do I request an NSK cup from this series?
- Send the cup part number by WhatsApp to MR Accesorios Industriales. We will quote it shortly. If possible, send a photo of the part or the housing dimensions to confirm the variant.
- Can it be replaced by another brand?
- Yes, tapered roller bearing cups are interchangeable between brands by part number and dimensions. If you bring a part number from another brand, we look for the equivalence by outer diameter, width and raceway angle.
