Don't have to struggle to choose what kind of pu castor to teng kai see became, anti-wind castor silk bearing selection is also must want to know. There are many kinds of, in fact, castor USES bearing without it, castor lost its use value. Therefore, the ideal bearing should be suitable for their respective applications, and keeping the necessary safety margin. Besides the rotation wheel, wheel diameter and bearing, wheel bearing determines the mobility of the caster wheel, even the quality of the caster. The use of different environments, have different requirements. Factories use castor is different from firms use castor, tools for different hospital bed with light-duty castor castor, shopping cart use castor requirements completely different castor carrying heavy load used in the factory. In general the following bearings: spirit, bearing. Spirit, is a special engineering plastics, suitable for humid and corrosive, rotational flexibility, resistance is bigger. Roller bearing: after heat treatment of the roller bearing can bear a heavy load, rotational flexibility. Ball bearing: choose high quality made of bearing steel ball bearings, can carry heavier loads, suitable for flexible rotation and peace required. Plane bearing: suitable for high and very high load and high speed. Usually choose a qualified castor products, they must be before they go out to the strict quality, performance testing, the following is to introduce enterprises to adopt several test: neutral salt spray test: electroplating products per the arrival of the goods are to be neutral salt spray test, can ensure 24 hours without white rust, barrel plating plating pieces of 48 hours without white rust. Rolling experiment: castor production after 24 hours, after the completion of rolling experiments according to the product requirements, set different products of different rotating speed, load, and the obstacles, products in the reach regulation as a qualified after stroke. Impact test: will castor vertical backward in impact testing machine test platform, using the rules from the corresponding height to the bottom of the free falling impact castor wheel surface, castor without damage as qualified. Static load test: the casters on the static load tooling, fixtures pressure above the corresponding weight, static measuring wheel deformation after 24 hours, after test to detect casters deformation does not exceed 3% of the wheel diameter, and the test after the completion of the caster can use normally regarded as qualified.
