6801 2RS is a thin profile high speed ball bearing manufactured with rubber seals on both sides to protect the bearing from dust or any possible contamination and pre-lubricated with grease so it is delivered ready to use. The inner and outer diameters of our 6800 series thin profile ball bearing rings have been minimized or thinned making them ideal for applications where light radial thrust or high speed combined loads are required in a limited space.
6801 bearing thin profile high speed ball bearing is used in applications where high speed is required in a limited space. It belongs to the thin profile bearing series which is known for its light weight and small size.
Design:
Deep groove: The bearing has deep raceway grooves on both the inner and outer rings to accommodate higher loads.
Single row: 6801 is a single row bearing which is the standard for deep groove ball bearings ensuring smooth operation and low friction.
6801 deep groove ball bearings are versatile and can be used in a variety of applications including:
Textile machines, robots, bicycles, printing presses, etc.
Industrial machinery: electric motors, pumps and conveyors.
Electronics: Small motors and fans.
Medical: Precision instruments and equipment that require reliable, smooth operation.
Automotive: Clutches, drives, gearboxes
High-speed capability: Due to its deep groove design, the 6801 can handle high rotational speeds with minimal friction.
Load handling: It supports both radial and axial loads, making it suitable for applications where combined loads are present.
Durability: Made from high-quality materials, it ensures long service life and resistance to harsh operating conditions.
Low maintenance: Sealed and shielded versions require minimal maintenance as they prevent contamination and retain lubrication.
Proper lubrication: Ensure bearings are adequately lubricated to minimize friction and wear.
Clean environment: Install in a clean environment to avoid contamination that affects performance.
Proper alignment: Ensure bearings are properly aligned during installation to avoid uneven load distribution and premature failure.
Periodic inspection: Check regularly for signs of wear or damage and replace if necessary to maintain optimal performance.

R crown retainer
This type of retainer is a “comb tooth” shaped crown ring that can be embedded in the rolling elements. Suitable for medium to high speed low friction deep groove bearings. Depending on the purpose, the retainer can be made of copper, steel, or polymer.
Q full ball
This type of bearing does not have any spacers between the rolling elements. This type of bearing is a full complement ball bearing or angular contact bearing in position 5. This design is only used under high load conditions where the friction torque is large.
