What caused the damage to the YRT rotary table bearings?

YRT rotary table bearing has also gained great development space.However, some quality issues also emerge.So what caused the damage to the YRT rotary table bearings?FRB Bearings would let you know the reason.

Incorrect installation method
1. Use brute force when installing, and directly strike the bearing with hammer to hurt the bearing the most;Is the main cause of deformation.

2. If the mounting is not in place, there is deviation in the mounting or not installed to the bearing position, resulting in too small bearing clearance.The inner and outer rings are not in the same center of rotation, resulting in different centers.

Six key heat treatment technology problems in bearing manufacture

If the improper heat treatment, bearing heat treatment is the core of the bearing manufacturer, one of the key technology of heat treatment process and the physical properties of raw materials determines the bearing the final hardness, uniformity of hardness, abrasion resistance and contact fatigue life.What problems will arise?

Heat treatment deformation
Bearing parts in heat treatment, there is the thermal stress and organization stress, the internal stress can overlay or partially offset each other, is complex and changeable, because it can as the heating temperature, heating rate, cooling, cooling speed, parts of the change of the shape and size changes, so the heat treatment deformation is inevitable. Understanding and mastering the change rule of bearing parts can make the deformation of bearing parts (such as the ellipse of the ring, the size increase, etc.) in a controllable range, which is conducive to the production. Of course, mechanical collision during heat treatment will also cause deformation of parts, but such deformation can be reduced and avoided by improved operation.
