Judge polyurethane casters specifications skills test

Judgment of pu castor specification skills, castor specifications of the general judgment way is watching bearing. The same diameter of casters. Such as light castor, medium casters, heavy-duty casters, super-heavy castor, method is to make the wheels and stents have different thickness or material. All pu castor's 600 series pu castor, surface blasting processing because of its high pu castor rolling friction when starting with an acceleration, traction test measurement after 5 s level, its size does not exceed 15% of the test load is qualified. Rotational resistance test is in linear or circular motion tester is installed on one or more pu castor, make its direction and driving direction into 90 & deg; 。 May cause the rubber surface and core part. Core rubber casters adopt soft rubber wheel surface, can very good protection on the ground, soft rubber wheel surface can absorb the shocks caused when moving objects, quiet, relative to the economy, widely used in various occasions. Avoid using cars, tractor trailer to haul. Avoid when carrying weight to one side. Avoid giving any impact ( Such as from falling have head, vibration, forklift, fork impact) 。 The key in the structure of support and quality can impact and shock resistance. Caster wheel turning radius: refers to the center of the rivet vertical line to the outside of the tire on the edge of the horizontal distance. Proper spacing of the steering caster wheel can be 360 degrees. Turning radius is reasonable or not directly affects to the service life of castor. The structure of the steering castor for devices under the equipment makes it free to move. Steering castor is divided into two main categories: single wheel is installed on the bracket, and only move along a straight line of the castor is called fixed steering castor. Shall not use, want to all sorts of different situations, respectively equipped with other reliable measures, such as the material of metal ware, the materials of the castor oil material and so on comprehensive balance, and want to consider some of the material can cause fouling on the ground. Welding point whether cracks or welded plate, if there is a loosening of nuts and bolts. Inspection equipment due to overload or violent impact of structural deformation, the weight is not evenly Shared by a one or two will be lead to deformation, castor castor wheels can't rotate. If it is inserted bar castor, ensure that equipment installation hole is not bent, and inserted rod connected. Using locknut or check washer to install castor, confirm that expansion rubber lining installation location tighten in place.
