What are the bearings of casters and how to choose them correctly?
Time：May 30,2022
Regarding how to choose a caster, I believe you already know how to select one, so a good caster is inseparable from its bearings. We all know that the use of casters cannot be separated from the auxiliary bearings. The caster bearings should be suitable for their application while also leaving enough safety margin. So how do we choose these caster bearings? Below, the host Xiaoban will teach you how to select them.
1. Tapered Bearings - Tapered bearings are one of the important components of rolling bearings. In particular, they have the advantage of extending the range of caster use and providing improved maneuverability compared to traditional bearings.
2. Roller Bearings - In addition to wear-resistant and deep groove ball bearings, this robust impact-resistant bearing is mainly used for transportation equipment casters. Compared to other bearings, roller bearings are known for their low installation height, relatively low rolling friction, and high load capacity. Wheels equipped with roller bearings should not move more than 4 kilometers per hour, close to human walking speed.
3. Precision Ball Bearings - Specially designed single-row radial precision ball bearings that meet German industrial standards (DIN) are of high quality among bearings. Wheels equipped with these ball bearings can maintain extremely low rolling resistance even under heavy loads.
4. Standard Bearings - The simplest form of wheel bearing structure is sliding or friction bearings. They are shock-resistant, require almost no maintenance, and can also improve corrosion resistance based on the properties of these materials. If we only need to use mobile equipment for short distances and low speeds.
