6210 Deep Groove Ball Bearing – OEM Replacement

Overview

The 6210 deep groove ball bearing is a high‑volume, standard bearing used across motors, pumps, conveyors, and general industrial rotating equipment. If you’re replacing an OEM part, this page is built to help you source the correct bearing quickly while matching the sealing and clearance that your application needs.

Applications

Common applications include electric motors, fans/blowers, centrifugal pumps, gear drives, material handling conveyors, and belt‑driven machinery. In cleaner environments, shielded configurations can reduce drag; in dusty or humid areas, sealed options help extend service life.

Compatible Machines

You’ll find 6210 bearings used in packaging lines, HVAC equipment, shop tools, agricultural implements, light gear reducers, and many OEM assemblies that rely on standardized bearing sizes. If your equipment has a parts manual, confirm the full bearing designation including any suffixes.

Technical Specifications

• Standard size reference: 50×90×20 mm (ID×OD×Width) — verify for your exact brand/spec
• Bearing type: single-row deep groove ball bearing
• Load capability: strong radial support with moderate axial load capacity
• Materials: bearing-grade steel (common) with options for stainless or specialty grades
• Lubrication: pre-greased (sealed/shielded) or re-greasable depending on configuration
• Options: Open, ZZ (metal shields), 2RS (rubber seals), and internal clearance variants such as C3

Cross References

Cross references commonly include 6210, 6210-ZZ, 6210-2RS, and 6210 C3 variants. Manufacturers may use different suffix formatting (e.g., 2RS1, DDU, LLU). Match the function (seal vs shield) and internal clearance rather than just the letters.

Replacement Information

Confirm the bearing by measuring the bore, outside diameter, and width or by reading the code on the old bearing. If you’re replacing a bearing that runs hot, at higher speed, or with tight fits, internal clearance (often C3) may be required. During installation, press only on the ring being fitted (inner ring for shaft fits, outer ring for housing fits) to avoid damaging the raceways.

Quick FAQ

Open vs ZZ vs 2RS? Open bearings have no closures; ZZ uses metal shields; 2RS uses rubber seals for better contamination control.

What does C3 mean? C3 is a common internal clearance option used when heat or tight fits reduce clearance during operation.
