Plastic ball bearing
It works without lubricant, for example, with lubrication-free
ball bearings made of plastic. Unlike
metal, it is true that the high speeds above 5,000rpm cannot be implemented, but only a few applications need to rotate with such incredible speed. Most applications usually run at
low load and
speed. Plastic ball bearings are always impressive when used in liquid media such as water or even chemicals.
But even in applications with
elevated temperatures up to 150°C, ball bearings made of plastic can be a better alternative. In addition, such bearings offer considerable advantages over metal in terms of easy movement. They run with significantly
lower breakaway torque so that they do not have to overcome the resistance of the lubricant. In addition, they are
very light, and upon request are also available with glass balls and thus are
completely metal-free and
non-magnetic. Grease ball bearings: not with xiros.
