1) Choose the right bearing capacity
The bearing capacity refers to the weight that the caster can bear when it is moved on a flat surface for a long time and smoothly. When calculating the caster load capacity, it is necessary to first estimate the total weight of the item, and then select the appropriate caster according to the number of casters matched.
(2) Choose the right bearing
Single ball bearing: Made of high quality bearing steel, it can withstand heavier loads and is suitable for flexible rotating and quiet applications.
Double ball bearings: not only maintain the advantages of a single ball bearing, but also reduce the gap between the wheel and the wheel, more stable when used.
TELLING BEARINGS: Tellin is a special engineering plastic that is suitable for wet and corrosive areas, has a general rotation flexibility, and has a high resistance.
Roller bearings: After heat treatment can carry a heavier load, rotation flexibility is generally.
Rivets: Rivets are mainly used for relatively few types of casters, such as small casters, because the casters are too small to mount the bearings, so the casters can be swiveled with rivets.
Center axis: Caster swing clearance is large, load is small, suitable for some smaller handicrafts.
Pressure bearing: Suitable for high-speed high-speed rotation, so it is often used in some special heavy machinery.
