Loss of cast iron castor with polyurethane casters to open a new life

Lost a cast iron castor with polyurethane casters to open a new life, on the one hand, due to the bending fatigue or hardness is not enough to make the roll surface concave part of meat edge; On the other hand may be a roll surface with foreign body, make the part surface convex shaped; Rolling or finish machining, the formation of step fly caster wheel steel plate surface concave and convex defects. Step: surface inclusions in fly caster wheel steel plate surface is irregular dot block or strips of non-metallic inclusions, its color generally with reddish brown, brown, gray, or a film. Reason for slab rolling after exposure, subcutaneous inclusions or existing rolling surface inclusions in the slab residues on step fly caster wheel steel plate surface; Furnace refractories and sediment etc. Nonmetal material falls on the slab surface, when the rolling pressure into the panel. Caster wheel according to the bearing capacity can be divided into small, medium and heavy-duty casters, heavy-duty casters mainly refers to the capacity in more than 150 kg, more than 1000 kg of super-heavy castor, commonly called the wheel size in 100 mm or more commonly, bracket plate more than 5 mm, commonly used bracket thickness is 5 mm, 6 mm / 8 mm / 10 mm, 12 mm or more generally for hosting more than 1 ton, heavy-duty casters in general the bigger the diameter and thickness, the greater the load. Can according to customer request to use environment, choose 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. Rubber tires or slack is likely to lead to serious breakage scroll is not stable, leakage, load is unusual, and floor damage and so on, timely replacement of damaged tires and bearing can reduce downtime due to damage of castor cost brought by the loss. Check after repair wheels, determine whether the bolt and nut tightening, as far as possible at all to use the locking bolt washer or locknut. If is loose, tighten the immediately. If the inside of the bracket with the loose wheel will be to the rotation of the wheels was damaged or not.
