category and usage analysis of roller accessories

The roller is composed of a variety of accessories, mainly including roller stamping bearing housing, roller bearing, roller seal, roller bracket, space sleeve, hook joint, cast steel rake, cylindrical pin, roller axle , circlip and slinger. Roller accessories can play an important role and value in the use of rollers, which can assist the use and maintenance of rollers . Let's take a look at the role of roller accessories.

1. 1，Roller stamping bearing housing: roller bearing housingis divided into two kinds, one is stamping bearing housing(steel), the other is cast iron (gray iron) bearing housing. Most of the stamped bearing housings are welded with steel pipes, and the cast iron bearing housings are extruded with steel pipes. The feature of the stamping housing is that the sealing effect is good and the overall bearing capacity is strong. The biggest feature of the cast iron housing is that the concentricity is high, but the bearing capacity is lower than the stamping housing. Based on the above advantages, We Aohua adopts the flanging process to increase the contact surface between the bearing housing and the roller , the bearing force is enhanced, and high concentric data can be achieved.

2，roller bearing: bearing is an important part of the roller , bearing quality directly affects the service life of the roller. In order to ensure product reliability,We Aohua company choose the roller bearings much more careful than the choice of other roller accessories.

3，roller sealing: roller sealing material is divided into polyethylene and nylon. The cost of polyethylene is low, but the wear resistance is relatively poor, on the contrary, the sealing cost of nylon material is relatively high, but the wear resistance is high (to identify whether it is nylon material, the seal can be put into the water, the sinking is the seal of nylon material, and the floating on the water is the seal of polyethylene material). Idler seal is divided into TD75 type, DTII type, TR type, TK type, QD80 type, SPJ type and so on nearly ten kinds according to the type of idler. Aohua company has its own unique sealing method, its specifications and models are complete,, we have obtained many customers' praise in the domestic and aboard market after many years of testing and professional engineers' demonstration.

4，roller axle: roller axle is divided into cold-drawn steel axle and ladder axle. the axle tolerance is controlled within one threading when we choose the axle.

5，circlip: the roller circlip is made of spring steel, which plays the role of fixing roller . The spring of good quality has good elasticity and variability. the idler runout wil be prevented well at the impact of external force.

6, slinger: the fixing parts on the axle is divided into axial fixation and radial fixation.
