- What is a Deep Groove Ball Bearing 6800 Series?
- The Deep Groove Ball Bearing 6800 Series refers to a specific range of ball bearings characterized by their deep raceway grooves, which allow them to handle both radial and axial loads. The '6800 series' indicates a thinner cross-section compared to standard bearings, making them suitable for applications with limited space.
- What are the common applications for 6800 series bearings?
- These bearings are commonly used in a wide array of applications including agricultural machinery (e.g., small motors, gearboxes), electric motors, pumps, bicycles, skateboards, robotics, and other industrial equipment where space is a constraint and high rotational speeds are required.
- How do I choose the correct size 6800 series bearing?
- To choose the correct size, you need to know the bore diameter (inner diameter), outer diameter, and width of the bearing. These dimensions are crucial for ensuring a proper fit in your machinery. Consult your equipment's manual or measure the existing bearing if available.
- What is the difference between shielded (ZZ) and sealed (2RS) bearings?
- Shielded (ZZ) bearings have metal shields on both sides to protect against larger contaminants while allowing some lubricant escape. Sealed (2RS) bearings have rubber seals on both sides, providing superior protection against dust, moisture, and retaining lubricant more effectively, making them ideal for harsh environments.
- How often should these bearings be lubricated?
- The lubrication frequency depends on the operating conditions such as speed, load, temperature, and environment. For sealed bearings (2RS), re-lubrication is often not required for their service life. For open or shielded bearings, regular inspection and re-lubrication according to manufacturer guidelines or application demands are recommended.
