I just want to say a massive thanks to Welink team. We had a really tight deadline for a prototype requiring specific deep groove ball bearings, and they were brilliant. They understood our needs immediately, rushed samples over, and followed up to ensure perfect performance. It's that attentive service that sets them apart. They've been a great help, and we're already looking forward to our next project together. Highly recommended.
Quick Facts: 6202 2RS at a Glance
Type: Single-row deep groove ball bearing
Dimensions: 15mm (ID) × 35mm (OD) × 11mm (W)
Sealing: Double-sided rubber contact seals (2RS)
Primary Use: Electric motors, appliances, and automotive components
The 6202 2RS deep groove ball bearing is a cornerstone component in rotating machinery, particularly in electric motor manufacturing. Engineered to handle both radial and moderate axial loads, its compact form factor and robust sealing make it an industry standard for environments prone to contamination.
This technical brief details the exact specifications, interchange data, and sourcing criteria for the 6202-2RS to help engineers and procurement teams make informed decisions.
6202 2RS Dimensions & Form Factor
Standardization is a key advantage of the 6202 series. Manufactured to universally accepted metrics, it serves as a seamless drop-in component across global housing and shaft designs.
• Inner Diameter (Bore): 15 mm
• Outer Diameter: 35 mm
• Width: 11 mm

Technical Specifications & Load Capacity
Beyond basic sizing, the internal geometry and material composition dictate the bearing's operational lifespan. The 6202 2RS typically features 8 steel balls (5.953 mm diameter), balancing high load-carrying capacity with reduced friction for motor applications.
| Specification | Typical Parameters |
| Material | Chrome steel (SAE-52100 or GCr15) |
| Dynamic Load Rating (Cr) | ~7,650 – 7,800 N |
| Static Load Rating (Cor) | ~3,600 – 3,750 N |
| Limiting Speed (Grease) | 13,000 – 20,000 rpm* |
| Weight | ~45 g |
*Note: Actual speed limits are heavily influenced by grease selection, seal contact friction, and operational temperature.
The Engineering Advantage of "2RS" Seals in Motors
Electric motors operate in environments where dust, moisture, and particulate matter are constant threats. The "2RS" designation indicates the presence of dual rubber seals. For motor manufacturers, this design provides three distinct advantages:
① Contaminant Exclusion: The physical barrier prevents micro-abrasives from scoring the raceways or degrading the rolling elements.
② Maintenance-Free Operation: These bearings are pre-lubricated and "sealed for life." By preventing grease leakage, they eliminate the need for costly post-installation relubrication.
③ Extended Lifecycle: By maintaining a clean internal environment and optimal lubrication, 2RS bearings significantly outlast open variants in standard motor applications.
Common Application Sectors
Thanks to its 15x35x11mm profile, the 6202-2RS is deployed across various power transmission and motor applications:
• Electric Motors: Fractional horsepower (FHP) motors, power tools, and industrial drives requiring quiet, vibration-free rotation.
• Household Appliances: Washing machine drums, dryer assemblies, and HVAC ventilation fans.
• Automotive Systems: Alternators, starter motors, and auxiliary drive components.
• Fluid Handling: Industrial water pumps and air compressors.
6202 2RS vs. 6202 ZZ: Selecting the Right Variant
Engineers frequently evaluate whether to use the rubber-sealed (2RS) or metal-shielded (ZZ) version. The decision hinges on the operating environment:
• Choose 6202 2RS (Rubber Sealed): Best for environments with dust, high humidity, or direct exposure to contaminants. They offer superior grease retention but have a slightly lower top speed due to seal-contact friction.
• Choose 6202 ZZ (Metal Shielded): Ideal for cleaner, high-speed applications where minimizing rolling resistance and heat generation is prioritized. However, they offer less protection against fine moisture and dust.
Manufacturer Cross-Reference (Interchange Codes)
Different global brands use proprietary suffixes to denote the same 15x35x11mm sealed bearing. The 6202 2RS is a direct replacement for:
• 6202LLU / 6202DDU
• 6202-2RS1 / 6202-2RSR
• 6202EE / 202PP / 6202-2NSL
Sourcing Criteria: Quality Indicators for Procurement
When vetting suppliers for bulk production lines, raw specifications are not enough. High-performance motor bearings demand strict quality control:
• Metallurgy: Ensure the supplier strictly uses SAE-52100/GCr15 chrome steel for maximum fatigue resistance.
• Precision Class: While ABEC-1 (P0) is standard, demanding motor applications often require ABEC-3 (P6) tolerances to minimize runout and noise.
• Lubrication: Verify the factory uses high-performance grease rated for a wide thermal spectrum (e.g., -20°C to +160°C) to prevent premature failure during motor heating cycles
