Talking about: Roller Bearing Cage and Heat Treatment

The basic type of drum roller bearings can be either window glass fiber reinforced polyamide (nylon) 66 holders (suffix T) or machined brass body holders (suffix MB). The glass fiber reinforced polyamide 66 adheres to a frame at a temperature of up to 120 ° C. If the bearing oil is smooth, the additives in the smooth oil will reduce the service life of the frame, and the aged oil will also have an adverse effect on the frame at low temperatures; therefore, it is necessary to pay attention to the oil change period.

Drum roller bearing heat treatment

The heat-treated FAG drum roller bearing has a task temperature of up to 150 ° C, and the bearing temperature of the outer diameter exceeding 120 mm can still maintain the dimensional stability when the temperature reaches 200 ° C. If the bearing is made of polyamide, it is necessary to pay attention to the binding of the frame data to temperature.

Bearing crack treatment method

1. A metamorphic layer formed by grinding force. During the grinding process, the surface layer of the workpiece will be subjected to the cutting force, compressive force and friction of the grinding wheel. In particular, the latter two functions to form a plastic deformation layer and a work hardened layer having a strong directivity on the surface layer of the workpiece. These metamorphic layers necessarily affect the change in the residual stress of the surface layer.

2. The secondary quenching burn will cause the surface layer stress of the nsk bearing workpiece to change. The secondary quenching zone is under pressure, and the material in the high temperature tempering zone below it has the largest tensile stress, which is the place where the crack core is most likely to occur. Cracks are most likely to propagate along the original austenite grain boundaries. Severe burns can cause cracks in the entire grinding surface (more cracking) and scrap the workpiece.
