6212 Open Single Row Deep Groove Ball Bearing For High-Speed Applications | 60x110x22 mm

6212 Open Single Row Deep Groove Ball Bearing For High-Speed Applications | 60x110x22 mm

The 6212 Open is a highly efficient, versatile ball bearing engineered for systems that demand rapid rotational speeds and low friction. Featuring an unsealed and unshielded design, it allows for unrestricted circulation of external lubricants, making it the perfect choice for enclosed systems with oil bath or circulating oil lubrication. With its precisely calibrated 60 mm bore, 110 mm outer diameter, and 22 mm width, this bearing delivers reliable medium-duty performance across a wide array of industrial and automotive powertrains.

6212 Deep Groove Ball Bearing 60×110×22 mm | 62 Series – Medium Duty | Unsealed & Unshielded

Manufactured with optimized internal raceway geometry, the 6212 accommodates moderate radial loads and axial loads in both directions. Because it lacks contact seals or shields, there is zero added friction from sealing components. This allows the bearing to reach superior operational speeds—up to 6,300 r/min in oil—while maintaining minimal heat generation and smooth, quiet rotation.

 

6212 Open Single Row Deep Groove Ball Bearing For High-Speed Applications | 60x110x22 mm

Comprehensive Applications

Ideal for environments where the equipment housing itself prevents contamination, allowing the bearing to run freely:

Industrial Power Transmission
  • Heavy-Duty Gearboxes and Speed Reducers
  • Enclosed Industrial Drives
  • Industrial Centrifuges
Manufacturing & Machining
  • Machine Tool Spindles (where external cooling is applied)
  • Automated Assembly Line Drive Systems
  • Paper and Textile Processing Rollers
Fluid & Air Systems
  • High-Speed Centrifugal Pumps
  • Industrial Compressors
  • Large-Scale Ventilation Fans
Automotive & Transportation
  • Transmission Gear Shafts
  • Automotive Engine Accessories
  • Powertrain Transfer Cases

Key Performance Features

01. Maximized Speed Capabilities

The completely open configuration eliminates seal friction and drag, allowing this bearing to achieve significantly higher RPMs than its sealed or shielded counterparts without overheating.

02. Unrestricted Lubrication & Cooling

Designed for environments with dedicated lubrication systems, the open sides permit continuous, free flow of grease or oil. This ensures optimal thermal dissipation and constant replenishment of the lubrication film.

03. Premium Chrome Steel Construction

Forged from high-purity GCr15 (SAE 52100) chrome steel, the rings and balls undergo strict heat treatment processes. This results in exceptional surface hardness, high fatigue resistance, and extended service life under continuous operation.

Design & Configuration

Supplied in its raw, open state, the 6212 offers engineers complete flexibility over the chosen lubrication method (whether grease packing or oil injection). Because its internal rolling elements are exposed, it should be installed in clean, well-housed environments protected from external dust, moisture, and debris.

"The optimal choice for high-speed, enclosed machinery where low-friction operation and seamless oil circulation are the top priorities."
