What are Inch Sized Ball Bearings?
An Inch Sized Ball Bearing is a type of rolling-element bearing that uses roller balls to separate two “races,” or bearing rings. These ball bearings have been manufactured to be Inch Sized Dimensions. The combination of the roller balls and bearing rings help to reduce surface contact and rotational friction across moving planes to accommodate axial loads.
Inch Ball bearings help to facilitate motion by distributing loads and reducing friction for applications that have a high-speed requirement, ultimately aiding in extending the working life of your equipment.
What are Rolling-Element Bearings?
Rolling-element bearings, commonly called rolling bearings, are bearings that carry a load by utilizing “rolling elements” between two concentric, grooved rings called races. The motion of the bearing races allows for the rolling elements to move with very little resistance and with little slide variance.
Some common types of rolling elements include ball, cylindrical, spherical, barrel, needle, spindle, or tapered.
What is the Difference Between Open, Shielded, and Sealed Rolling Bearings?
The main difference between open and sealed/shielded bearings is the application of lubrication. The main difference between sealed and shielded bearings is the presence of a protective enclosure.
- Sealed and shielded bearings are lubricated with grease in the bearing factory. However, a rubber sealed bearing protects the bearing by using a seal that contacts the inner and outer race. This provides superior protection at the cost of operating speed and temperature.
- Open bearings are meant to be lubricated with light oil, with periodic reapplication of lubrication, based on use.
- Shielded rolling bearings contain an enclosure that helps to protect the working parts of the bearing from environmental debris that may be introduced and would otherwise reduce the ball bearing speed and lifespan. This metal shield is stamped onto the bearing and only contacts the outer ring, this allows for protection without sacrificing operating speed or temperature.
