Castor specifications, castor specifications
Bearing of castor specifications: general factory can produce several series for different bearing, general judgment way is watching bearing casters specifications. 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. Caster and specifications of the bearing, the load of a single caster will offer certain peace coefficient, when the ground is flat, a single caster wheel load = ( Equipment had been present on the caster and quantity) 1. 2 safe coefficient) As if the ground not level off, the algorithm, the total weight of a single caster wheel load = equipment present 3 because no matter what kind of uneven ground, always at least three wheels support equipment at the same time, the algorithm is equal to increase the safe coefficient, more reliable, to prevent the bearing is not enough, lead to greatly reduce or castor life lead to accidents. Castor specifications in foreign company, bearing generally expressed in pounds, and most domestic use kg, conversion relation is 2. 2 pounds = 1 kg. According to the different bearing, castor is bearing wheel. To determine the size of the caster and specifications. So, in general, castor specification is in accordance with the size of the caster and bearing to distinguish. Size of caster specifications: to promote the energy, the caster wheel size master: general caster wheel diameter is larger. The obstacle ability the better, because the castor first at the end of the 19th century the western industrialization, so castor generally represented in inches. According to specification, the size of the castor Chinese supermarket trolley are mostly with 5 inch, 4 inch caster wheel. The current market popular castor size from 1 to 10 inches, the size of the commonly used 2 inch, 2. 5 inch and 3 inch, 3. 5 inch and 4 inch, 5 inch, 6 ', 8 ', 10 ', such as general often need to promote such as supermarket shopping cart, logistics trolley, factory is 4 6 inch castor is preferred. But too much caster wheel diameter can make equipment center of gravity rises, interest rates increase, so must carry on the comprehensive consideration. If the device does not need to often push, such as furniture, refrigerator, etc. , only need to move, when cleaning choose 3 inches below the caster wheel can. / news_49。
