Before using pu castor should check whether there is loose phenomenon, check pu castor castor tightness structure and regular in the side or on both ends of the rotating pu castor castor, check the following: whether welding at point or welded plate fracture, loosening of nuts and bolts have check equipment due to overload or violent impact of structural deformation, the weight is not evenly Shared by one or two pu castor castor will lead to pu castor castor deformation, wheel can not turn if it is match the pu castor castor thrust rod, to ensure that equipment installation hole is not bent, and inserted link closely linked. Using locknut or check washer to install castor confirm whether expansion rubber sets of installation location tighten in place to add lubricant to add lubricant to pu castor castor or wheels on a regular basis. Add frequency depends on the specific usage, generally every half a lubricating oil, but in humid and corrosive environment best additional once a month, every time cleaning the caster equipment also want to add a lubricant, on these occasions must use high temperature resistant and waterproof grease. In the process of use on a regular basis to pu castor castor and add the lubricating oil bearing, where prone to friction lubricating until there are a few overflow, such as wheel core, thrust washers, roller bearing roller surface, can reduce friction rotation is more flexible.
