When testing the performance pu castor should keep dry and clean, place the caster in a piece of insulation on the metal plate with the ground, keep the wheel edge in contact with the metal plate, on the pu castor load of 5% to 10% of the nominal load. With the insulation resistance tester ( Nominal open circuit voltage of 500 v, determination of the resistance value of fluctuation within 10% and no more than 3 w) in the wastage of the products The electric resistance between castor and metal plate. Professional about pu castor abrasion test impact test: when moving castor or to control the moving direction, the power must be on the object to the caster and to overcome certain resistance, resistance depends on the size of the: weight, wheel diameter, material, round face shape, pu castor rotating field. Reciprocating wear testing: tapered bearing. Korean universal casters so when they suddenly overloaded or 4 only 3 other pu castor only contact with the ground, must carry the entire load of furniture. Needle roller bearings. Needle roller bearing is mainly used in universal wheel, needle roller bearing and other bearing differ in that it has very low installation height, have quite a low rolling resistance, but also have huge bearing capacity. But the disadvantage of needle roller bearing is not good for high speed, using a needle roller bearing industrial casters most inappropriate driving faster than the rate of four miles per hour. So what are introduce in this industrial caster wheel bearing? Castor reciprocating wear test to simulate the casters in daily use the actual rolling, the two points with and without obstacles obstacles test test, the test process are not allowed to have pu 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 polyurethane caster roll, circuition or brake function should not be damaged. Castor to use a very wide range, according to statistics, industrial casters is one of the largest in purchasing consumption demand, but people often pay attention to when purchasing castor castor material, size, bracket plate thickness and welding process, but ignores the problem of bearing, so the zhongshan castor business must remind everybody, bearing strong degree also can affect the trundle bearing capacity and service life directly. 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. Pu pu castor castor manufacturers for conductivity, resistance is not more than 104, and the resistance of the antistatic caster should be between 105 and 107. Rolling resistance and rotation resistance measurement: precision ball bearings. Precision ball bearing is single rotate in the ball bearing, the make and model of the highest quality with the ball uniform radiation can arrangement is very effective to reduce rolling resistance, it also has very high bearing capacity. Cone bearing compared with other bearing is the biggest advantage of general, can be used is suitable for all kinds of pu castor, and have a good ability to move on. Castor should always be steady running on the ground, but it is almost a state of pure theory. On the uneven surface, or in a threshold, orbit and potholes, castor will brief off the ground. ( )
