Note - castor use

Universal wheel, adjust the foot manufacturer when we are in the use of casters and wheels, we take into account not only his conditions, functions and USES, the use of type fit is important. ( 1) Choose suitable bearing capacity refers to the caster and long-term, smooth moves on the flat floor can carry weight, to calculate the bearing capacity of castor, items need to estimate the total weight, then according to the number of castor collocation choose appropriate castor. ( 2) Choose the right bearing single ball bearing: adopt high quality bearing steel manufacturing, can carry heavier load, suitable for flexible rotation and quiet place. Double ball bearing: it keeps the advantages of single ball bearing, and reduce the clearance between the wheel and the wheel, when using more stable. Spirit spirit, bearing) is a kind of special engineering plastics, suitable for humid and corrosive, rotational flexibility, greater resistance. Roller bearing: after heat treatment can carry heavier load, rotational flexibility. Rivet, rivet is mainly used for relatively small number of castor type, such as small casters, because castor is too small, can't install the bearing, so can use rivet rotating caster wheel. Central axis: castor swing gap is big, small load, suitable for some of the smaller handicrafts. Pressure bearing: applicable to high load high speed rotation, so it is often used in some special heavy machinery. Plane bearing: applicable to high, high load and high speed. ( 3) Commonly used brake brake rigidity, with brake parts and surface friction of single wheel, a braking effect, but use after period of time, locking the effect will be reduced. ( 4) Environmental conditions using castor castor commonly use environment is given in the indoor environment at room temperature, so you need to avoid as far as possible in special environments, such as high temperature, low temperature, acidity, alkalinity and salinity, chemical solvents, oil, water, etc. For use in a specific environment, we have to choose high temperature resistant, good low temperature resistance, stainless steel, chrome and other special process of castor.
