6204-2RS Deep Groove Ball Bearing – OEM Replacement

Overview

The 6204-2RS deep groove ball bearing is a go-to OEM replacement for compact industrial drives where you need smooth running, low noise, and sealed protection. It supports radial loads efficiently while handling moderate thrust loads, making it a common choice across motors, pumps, and general machinery.

Applications

Typical applications include medium-size electric motors, belt-driven fan assemblies, small conveyors, agricultural equipment, and light-duty gear reducers. Double rubber seals help reduce contamination ingress and improve uptime in dusty or moisture-prone environments.

Compatible Machines

You’ll see 6204 bearings in HVAC equipment, shop machinery, small compressor accessories, and general-purpose rotating shafts. It’s also commonly used in pump ends where grease retention and splash resistance matter.

Technical Specifications

  • Bore (ID): 20 mm
  • Outside Diameter (OD): 47 mm
  • Width: 14 mm
  • Sealing: 2RS rubber seals (double sealed)
  • Typical material: chrome steel (52100) or equivalent
  • Lubrication: pre-greased for general-purpose duty

Cross References

Common equivalents include 6204, 6204-2RS, 6204-RS, 6204-ZZ, and brand-specific suffixes. Match any existing clearance (C3, C4) or temperature-rated grease requirements to preserve performance.

Replacement Information

Confirm the bearing designation and measure ID/OD/width. Inspect shaft journals and housings for wear, and replace in pairs when practical. Choose sealing based on environment: 2RS for protection, ZZ for higher speed with less seal drag.

Why Source With Us

We specialize in sourcing OEM replacement bearings with options for premium grades, specialty clearances, and multiple sealing configurations. Send an RFQ with your machine model or bearing code for fast quoting and alternatives.

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.
