The simplest form of ordinary bearings-cast-wheel bearings is the sliding or rubbing of bearings. They are earthquake-resistant, almost maintenance-free, and are resistant to corrosion based on the properties of the material.
Roller bearings-In addition to wear-resistant and deep groove ball bearings, these strong, earthquake-resistant bearings are mainly used to transport equipment casters. Compared with other bearings, roller bearings are known for their extremely low installation height, relatively low rolling resistance, and huge load weight. Wheels with roller bearings must not move more than 4 km/h, which is close to the speed at which people walk.
Cone bearing-cone bearing is one of the most important components of roller bearing. Compared with ordinary bearings, they have the special advantage of expanding the area of use and providing improved mobility characteristics.
Ball bearings-Single-row spokes precision ball bearings that are uniquely designed and conform to German industry standards(DIN) are the highest quality models in bearings. Wheels equipped with these ball bearings can maintain very low rolling resistance even if they carry a maximum load.
