We live to see the chair casters, furniture casters on the table and brought great convenience to our life, in fact, castor is not produced will be able to use, he needs through a series of tests can be put into market, different castor test requirement is different, the eastern rui castor show all casters through which tests can be put into market.

　　

Heavy duty casters resistance test: the casters should be dry and clean when testing this property. Place the casters on a metal plate insulated from the ground, keep the sides of the casters in contact with the metal plate, and load the casters with 5% to 10% of their nominal load. Measure the resistance between the caster and the metal plate with an insulating resistance tester (nominal open circuit voltage 500V, the measured resistance fluctuates within 10% and the loss on the product does not exceed 3W). For conductive casters, the resistance should be no more than 104 ohms, while for antistatic casters, the resistance should be between 105 ohms and 107 ohms.

Impact test: any goods transportation, use, preservation and other situation will impact vibration may be produced and make the product a certain period of time can't normal use, the furniture with its type, weight and other characteristics are often vulnerable to the impact, and at the bottom to determine whether furniture placed truckle is more smooth should possess good shock resistance.Static load test: the caster should always operate steadily on the ground, however, that is almost a purely theoretical state. Casters leave the ground briefly on uneven surfaces, or when crossing thresholds, tracks, and potholes. So when they're suddenly overloaded or three of the four casters touch the ground, they have to carry the load of the entire piece of furniture.Reciprocating wear testing: castor reciprocating wear test to simulate the casters in daily use the actual rolling, the two points with and without obstacles obstacles test test, in the process of test are not allowed to have a castor or other parts from, at the end of the test each castor should be able to drive its normal function, test after the completion of the caster roll, circuition or brake function should not be damaged.Rolling resistance and rotating resistance measurement: when the caster moves or wants to control its driving direction, the force must pass through the object to the caster and overcome certain resistance
