110mm inner diameter 145mm outer diameter bearing

Golden Deer Bearings are a crucial tribological component of many types of
machinery and exist in a variety of forms and shapes. They can be defined as a
component that supports/permits only a specific type of motion (restriction of
degrees of freedom) in a system that may be under static or dynamic loading.
The main purpose of bearings is to prevent direct metal to metal contact
between two elements that are in relative motion. This prevents friction, heat
generation and ultimately, the wear and tear of parts. It also reduces energy
consumption as sliding motion is replaced with low friction rolling.
They also transmit the load of the rotating element to the housing. This load
may be radial, axial, or a combination of both. A bearing also restricts
freedom of movement of moving parts to predefined directions as discussed
above.
