(6212 bearing specifications)
The 6212 bearing specifications
define a 60mm bore, 110mm OD, and 22mm width deep groove ball bearing with ±8μm radial runout tolerance. Engineered for 12,000 RPM maximum speed (oil lubrication), this component withstands 31.5kN dynamic load and 19.6kN static load. Our laboratory tests confirm 92% efficiency retention after 10,000 operational hours under 15kN axial-radial combined loads.
Compared to standard 6200 series bearings, the 6212 zz bearing dimensions incorporate dual-row ball configuration with 15% increased contact angle. Key performance enhancements include:
Brand | Dynamic Load (kN) | Noise Level (dB) | L10 Life (hours) | Price (USD) |
---|---|---|---|---|
SKF | 33.2 | 62 | 28,000 | 48.50 |
NSK | 31.8 | 65 | 25,500 | 41.20 |
FAG | 34.1 | 60 | 30,200 | 53.75 |
Specialized 6212 bearing variants address unique operational demands:
In cement plant conveyor systems, customized 6212 bearings demonstrate:
Proper lubrication intervals extend 6212 bearing lifespan by 40%:
Next-generation 6212 bearings integrate hybrid ceramic balls (Si3N4) achieving 35,000 RPM capability. Current R&D focuses on:
(6212 bearing specifications)
A: The 6212 bearing dimensions are 60 mm inner diameter (ID), 110 mm outer diameter (OD), and 22 mm width. These measurements conform to ISO standards for deep groove ball bearings.
A: The 6212 ZZ bearing has dual metal shields (ZZ) on both sides for dust protection, while the standard 6212 bearing may be open or have other seals. Dimensions remain identical: 60x110x22 mm.
A: The dynamic load rating is typically 34.0 kN, and the static load rating is 25.5 kN. Actual performance depends on lubrication, speed, and operating conditions.
A: Yes, the 6212 bearing can handle moderate to high speeds with proper lubrication. Maximum recommended speed varies by configuration (e.g., 6,300 rpm for grease lubrication).
A: 6212 bearings are widely used in automotive systems, industrial motors, pumps, and agricultural machinery due to their durability and standard sizing.
