● Materials and heat treatment for Forklift mast bearing ring
The selection of materials for mast-bearing rings (including shafts) is based on the different loads and structures borne by bearing ring parts. Generally, bearing steel, high-quality carbon structural steel, carburized steel, and other materials are selected for manufacturing. Different heat treatment processes are utilized to obtain the mechanical properties for bearing ring parts.

● Load and structure of the forklift mast bearing
In mast bearings, the magnitude of the load is the first factor to consider when selecting bearings. Under the condition of the same overall dimensions of the bearings, the bearing capacity of the roller structure is the largest, followed by double. -row ball structure and the bearing capacity of a single-row ball structure is relatively small. Among the bearings of this type of structure, the bearing load capacity of the full-ball (or roller) structure is larger than that of a bearing with a cage. On the premise of sufficient load capacity, the standard single-row ball structure can be preferred.

● Differences between forklift mast bearings and other standard bearings
Compared with other standard bearings, the mast bearings are mainly distinguished in that the inner ring is stationary relative to the shaft and the outer ring is rotating, and reciprocating according to a certain rule (time or stroke), bearing constantly changing loads during movement.

● Differences between the forklift mast bearing and other standard bearings in movement
During the movement, the outer ring of the mast bearing repeatedly rubs against the track surface and continuously wears. According to the different track materials, the surface hardness of the bearing shall be reasonably determined, and both track protection and bearing service life shall be considered.
