The rotation of the polyurethane casters have specific structure

Polyurethane casters have the rotation of the concrete structure, the market has polyurethane foam composite materials that are used for various specifications ( Two-component premix) Mainly used for ( Cold cure) High resilience foam, half hard foam plastic, casting and spraying hard foam plastic, etc. Polyurethane elastomer can be in a wide range of hardness has high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and seismic resistance, with & other; Wear-resisting rubber & throughout; Said. Select different bracket and the wheels of the material. Through the buffer shock absorption structure road uneven on the impact of the carrier, guarantee the smooth, in the process of vehicle handling of parts in the process of slow transportation vibration and damage, shock absorbing material generally is rubber shock absorption and spring damping two kinds, glue and rubber rubber and polyurethane rubber piece, spring suspension style is more, a single coil and looks, springs and tree spring and spring suspension, universal wheel loose castor wheels or jammed also can cause & other; Grinding flat spot & throughout; , the appropriate maintenance check, especially check bolt tightness, lubricating oil, to replace the damaged rolling performance and rotary motion of the universal caster wheel can enhance flexibility. For moving heavy objects to the direction of the change is still very difficult, then people invented with a steering wheel structure, that is what we now call the castor or universal wheel. Castor appeared to people carrying especially moving object has brought the era of the revolution, not only can easily carry, can also with any direction, greatly improving the efficiency. Castor also is what we call the universal wheel, its structure is allowed to rotate 360 degrees; Fixed castor no rotational structure, can't turn. Usually two casters are generally use collocation, such as the structure of the trolley is in front of two fixed wheel, behind near the armrest is driven by two wheels.
