608-2RS Deep Groove Ball Bearing – OEM Replacement

Overview

The 608-2RS bearing is a globally popular deep groove ball bearing size used in everything from small motors to rollers and idlers. As an OEM replacement, it offers reliable performance in compact designs where sealed protection improves service life.

Applications

Common uses include small electric motors, rollers, conveyors with small idlers, wheels, and various light-duty rotating parts. The 2RS seals are helpful when the bearing is exposed to dust, moisture, or intermittent splash.

Compatible Machines

You’ll frequently see 608 bearings in small driven rollers, compact automation modules, and general-purpose assemblies. Because this size is often used in high-RPM applications, matching grease type and bearing quality can have a big impact on noise and longevity.

Technical Specifications

  • Bore (ID): 8 mm
  • Outside Diameter (OD): 22 mm
  • Width: 7 mm
  • Sealing: 2RS rubber seals (double sealed)
  • Typical material: chrome steel (52100) or equivalent
  • Lubrication: pre-greased for general-purpose duty

Cross References

Cross references include 608, 608-2RS, 608-RS, 608-ZZ, and equivalent codes used by major manufacturers. If you need low-friction performance at high speed in a clean environment, ask about shielded or low-drag seal options.

Replacement Information

Confirm dimensions (8×22×7 mm) and any suffixes. Inspect the shaft for wear and ensure correct fit. Avoid pushing through the balls during installation. If the application is high-speed, consider selecting premium grade and the correct lubrication.

Why Source With Us

We can source OEM replacement 608 bearings in multiple sealing options and quality levels, and we’ll recommend the best fit for your speed and environment. Submit an RFQ with quantity and application notes for fast sourcing.

Quick FAQ

What does the suffix mean? Common suffixes include ZZ (metal shields) and 2RS (rubber seals). Seals help retain grease and exclude contamination.

How do I confirm fit? Match the bearing designation, bore size, OD, and width. If your old bearing has an extra internal clearance suffix (like C3), keep that specification.

Can I upgrade quality? Yes—use premium grades for higher speeds, higher temperatures, or continuous-duty service.

FAQ

You can identify a replacement industrial part by matching key specifications such as dimensions, mounting style, material, load capacity, voltage, speed rating, and application. Many industrial components can be sourced by size and performance specifications even if the original part number is unknown. Providing measurements, photos, or equipment model information can help ensure accurate identification and compatibility.

Yes. Many industrial components — including bearings, seals, belts, motors, and fasteners — can be identified using inside diameter, outside diameter, width, thread size, or mounting pattern. Matching exact dimensions is one of the most reliable methods for finding equivalent or replacement parts when a part number is missing or unreadable.

Machine model numbers can often be used to locate OEM parts diagrams, exploded views, and manufacturer replacement lists. These references help identify compatible components originally installed in the equipment. Matching parts by machine model ensures correct fit, performance, and operational reliability.

OEM part numbers can be cross referenced using manufacturer interchange guides, engineering specifications, or industrial databases. Matching dimensions, tolerances, materials, and performance ratings ensures the alternative component functions the same as the original.

To confirm interchangeability, compare critical specifications such as dimensions, mounting configuration, operating capacity, material composition, and tolerance class. If these parameters match, the components are typically interchangeable across manufacturers.

Installing an incompatible part can lead to premature wear, mechanical failure, reduced efficiency, overheating, vibration, or equipment damage. Always verify specifications and compatibility before installation to maintain performance and safety.

Metric and imperial components may appear similar but often differ slightly in size and tolerance. Even small measurement differences can affect fit and performance. Always verify exact measurements before substituting between measurement systems.

 

Tolerance ratings define the allowable variation in size, alignment, or performance. Tight tolerances improve precision, reduce vibration, and extend equipment lifespan.
