Pressure roller bearing used for pallet cars in sinter plant

The pressure roller bearings are mainly used in the continuous furnaces of sintering plants. They are massive bearings ready to be fixed. They are used with heavy loads and where the rotation reverses continuously at low speed.
The outer ring shows three entire borders, one section and one outer surface which is highly resistant to wear.
The inner ring is made of two parts, each one has an entire border expressly developed in order to bear high axial thrusts, in addition to radial loads.
Pressure roller bearings do not need maintenance.
The outer ring and the inner ring are manufactured in GCr18Mo steel.
Hardness 60-2 HRC.
In order to increase the resistance to wear, pressure roller bearings usually undergo bainitic temper treatment up to 250° C, named S2.
The sealing system foresees the presence of Viton O-rings, which are inserted in the proper grooves on the inner ring. The seals allow the bearing to be disassembled, they prevent the entrance of contaminating agents and in the meantime, the leakage of lubricant.

U profile stud type track roller bearings used for guide rails

The new finished U profile stud type track roller bearings with ball & cage structure, the oil seal design can prevent the contaminants outside.

The bearings can support high radial- and axial forces in both directions. The special curved shape of the outer ring creates two contact surfaces with the guide rail.

With these track roller bearings, carriages will run quickly and quietly on guide rails.

These track rollers are lubricated and maintenance-free during their service-life.
