There are many types of pu castor how do we choose? For heavy duty caster wheel bearing choice according to the various special castor requirement, can choose the appropriate attachments. Such as dust cap, sealing ring and anti-wind cover can maintain the cleanness of heavy duty castor rotating parts, prevent all kinds of fiber entanglement, make flexible casters use for a long time still the same; Stopper and double brake switch device can effectively prevent the rotation of the castor and steering, so you can stay in any position. 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 heavy duty castor high and very high load and high speed. Characteristic of polyurethane pacify castor: installation height: refers to from the ground to the vertical distance between equipment installation position, the installation of the castor height refers to remote the largest vertical distance and castor base plate and the wheel. Stand to center distance: refers to the vertical line to the center of the wheel core center rivet horizontal distance. When equipment has fundamental impact or vibration of the castor instantaneous load bearing capacity. Static load and static load static load and static load: castor can bear the weight of the under stationary state. Static load generally should exercise load ( Dynamic load) 5 ~ 6 times, static load should be at least 2 times the impact load. Hard, narrow wheel than soft, wide wheels turn more easily. Rotate wheel radius is one of the important parameters, short turning radius increases to the difficulty, too much will cause the wheels wobble and shorten the life. Suspension of castor structure composed of single wheel is installed on the bracket, used to install below the equipment makes it free to move. Mainly in such aspects as trolleys, mobile scaffolding, workshop van is very widely. Various types of single wheel casters, turning the 360 degrees with single wheel, can freely in any direction of call activities castor. Castor fixator with the single wheel, only move along a straight line. Single wheel casters are varied in size, type, different tyre tread, etc. Choose the right wheels come from the following several conditions: use the space environment; The product load; Work environment containing chemicals, blood, grease, oil, salt and other substances; All kinds of special climate, such as humidity, high temperature or cold shock, collision and driving E quiet a lot of different factors determine your choice of castor, the bearing capacity of the castor is the most basic and the most critical requirement of castor, therefore, of the bearing capacity of the caster in actual choice, should leave the certain safety margin. One castor dangling, this method is suitable for the shipment or equipment in the process of mobile casters under the force of the large, poor ground condition, especially in the case of the total weight is bigger.
