6214 Open Deep Groove Ball Bearing | High-Speed Oil-Lubricated Performance | 70×125×24 mm

6214 Open Deep Groove Ball Bearing | High-Speed Oil-Lubricated Performance | 70×125×24 mm

The 6214 is a premium, unshielded single-row deep groove ball bearing designed for applications where lubrication is supplied by an external system, such as an oil bath or circulating oil mist. By eliminating internal seals or shields, this bearing provides the lowest possible rotational friction, making it the ideal choice for high-speed machinery and precision gearboxes. With a 70mm bore and a robust 125mm outer diameter, it offers high structural integrity and the versatility to handle significant radial loads in clean, controlled environments.

6214 Deep Groove Ball Bearing 70x125x24 mm | Open Type | Maximum Lubricant Flow

This open-configuration bearing is engineered for maximum thermal efficiency and ease of maintenance. Without the restriction of physical seals, lubricants can flow freely through the raceways, ensuring optimal cooling during continuous high-RPM operation. It is a critical component for internal mechanical assemblies where the bearing is protected by a housing, allowing for seamless integration into complex power transmission systems.

 

6214 Open Deep Groove Ball Bearing | High-Speed Oil-Lubricated Performance | 70×125×24 mm

Comprehensive Applications

Ideally suited for internal mechanical systems, oil-immersed environments, and high-speed industrial equipment:

Fluid Handling & Processing
  • Chemical Processing Pumps
  • High-Volume Centrifugal Pumps
  • Oil-Cooled Compressors
  • Internal Engine Components
Manufacturing & Heavy Machinery
  • CNC Machine Tool Spindles (Oil-Lubricated)
  • Hydraulic Pumps and Motors
  • Precision Milling Equipment
  • Printing and Textile Machinery Rollers
Industrial Gearboxes & Transmissions
  • Heavy-Duty Speed Reducers
  • Automotive and Truck Transmissions
  • Industrial Drive Trains
  • Planetary Gear Systems
Power Generation & Distribution
  • Large-Scale Turbines
  • High-Speed Centrifuges
  • Internal Generator Supports
  • Fluid Coupling Assemblies

Key Performance Features

01. Ultra-Low Frictional Torque

The open design removes all contact resistance from seals, resulting in exceptionally low starting and running torque. This maximizes energy efficiency and allows the bearing to reach higher limiting speeds compared to shielded or sealed variants.

02. Premium GCr15 Chrome Steel Construction

Manufactured using high-purity GCr15 Chrome Steel (SAE 52100) and heat-treated for maximum hardness. The deep, high-precision raceways are ground to fine tolerances to ensure quiet operation and minimal vibration under heavy load.

03. Enhanced Heat Dissipation

Because the internal components are exposed, heat generated during high-speed rotation is quickly dissipated through the circulating lubricant. This prevents overheating and extends the operational life of both the bearing and the grease/oil.
