Roller accessories may include roller frame, conveyor idlers, spacer sleeves, hook joints, cast steel rakes, cylindrical pins, etc. All these accessories play an important role in the operation of rollers and can assist the use and maintenance of the rollers.
Roller accessories refer to various parts constituting rollers, mainly including the following
- Pressing roller bearing seat: It's divided into pressing bearing seat and cast iron (gray iron) bearing seat. The pressing bearing seat is mostly welded with steel pipe, which has good sealing and strong overall bearing capacity; Cast iron bearing seat is extruded with steel pipe, which has high concentricity but relatively low bearing capacity.
- Roller bearing: Bearing is the most important part of the roller, its quality directly affects the service life of the roller.
- Roller sealing: The material is divided into polyethylene and nylon. Polyethylene has low cost and relatively poor wear resistance; Nylon material cost is relatively high, but has good wear resistance. The roller sealing is also divided into TD75, DTII, TR, TK, QD80, SPJ and other types.
- Roller shaft: It is divided into cold-drawn steel shaft and stepped shaft, and its tolerance must be guaranteed within a certain range (for example, between 0.002mm and 0.019mm).
- Circlip: It is made of spring steel, it plays the role of preventing the axial movement of the roller.
- Retaining ring: It's used to fix the parts on the shaft, which is divided into axial fixing and circumferential fixing.
The characteristics of roller accessories include wear resistance, long service life, light weight, small rotation inertia, reasonable structure, reliable sealing and superior anti-corrosion properties. These characteristics make the roller accessories been widely used in belt conveyor, conveyor and other equipment.
