Product Overview

M86648A/M86610 is an inch-series single-row tapered roller bearing designed for compact mechanical systems and general industrial applications that require reliable support for combined loads, accurate shaft positioning, and stable running performance. This bearing set consists of cone M86648A and cup M86610, and its metric reference dimensions are 30.955×64.292×21.433mm.

Although the product page displays dimensions in millimeters, the part number structure and decimal sizing clearly indicate an inch-series tapered roller bearing. In international bearing trade, inch-series bearings are often shown with mm conversions to make sourcing and comparison easier for overseas buyers.

What is M86648A/M86610 Bearing?

M86648A/M86610 bearing is a single-row tapered roller bearing assembly used in applications where the system must support radial loads, axial load in one direction, stable shaft guidance, and reliable operation in compact installation space.

What Do M86648A and M86610 Mean?

In this bearing designation:

  • M86648A usually refers to the cone assembly (inner ring + tapered rollers + cage)

  • M86610 usually refers to the cup (outer ring)

Depending on the purchasing requirement, customers may request the complete bearing set, the cone only, or the cup only. For replacement sourcing, it is important to confirm whether the buyer needs the full set or only one component.

What Does the “A” Suffix in M86648A Mean?

The “A” suffix in M86648A should be kept exactly as listed when ordering or cross-checking. In bearing designation systems, a suffix like A may indicate a specific design variant, dimensional revision, or manufacturer-defined configuration within the cone series.

For this reason, buyers should not omit the suffix and should not assume M86648A is identical to M86648. Final interchangeability should be confirmed by drawing, catalog data, or approved sample.

Is M86648A/M86610 an Inch Bearing or a Metric Bearing?

M86648A/M86610 is best described as an inch-series tapered roller bearing. The source page lists the dimensions in mm, which are commonly used as international reference values in product listings.

When supplied in a sealed version, the bearing may be pre-lubricated with grease. Final sealing type and lubrication condition should always be confirmed before quotation or production.

Material Information

The source listing indicates that M86648A/M86610 is made from chrome steel. Common material references for this type of bearing may include 52100, GCr15, SUJ2, and other equivalent bearing steel grades depending on market standard.

Chrome steel is widely used in bearing manufacturing because it offers good hardness after heat treatment, strong wear resistance, reliable rolling contact fatigue performance, and stable dimensional behavior in service.

What Loads Can M86648A/M86610 Support?

M86648A/M86610 is mainly designed for:

  • Radial loads

  • Axial load in one direction

  • Combined-load mechanical systems

  • Compact rotating equipment

Because of its tapered roller design, this bearing performs well where radial force is the primary load and axial positioning is also required.

Applications of M86648A/M86610

M86648A/M86610 may be used in:

  • Trailer and axle assemblies

  • Hub-related mechanical systems

  • Automotive replacement applications

  • Agricultural machinery

  • Compact gearboxes and reducers

  • Mechanical drives

  • General industrial machinery

  • Other shaft support positions requiring an inch-series tapered roller bearing

If your application requires a reliable 30.955x64.292x21.433mm tapered roller bearing with dependable combined-load support, M86648A/M86610 bearing is a practical solution for replacement, maintenance, or OEM sourcing.

Optional Technical Configurations
