What factors affect the flexibility of casters

There are many factors affecting the flexibility of casters, which can be roughly categorized as follows:

Material quality: on a relatively flat ground, hard materials rotate more flexibly, but on uneven ground, soft wheels are more labor-saving.

Wheel surface size: the smaller the area of contact between the wheel and the ground, the more flexible the rotation, so many wheels are designed with a curved surface, the purpose is to reduce the contact area with the ground.

Bearing type: bearings are generally categorized into: single ball bearings, double ball bearings, roller bearings and so on.

Bearing lubrication: Proper bearing lubrication can reduce friction and improve the rotation efficiency of casters, thus increasing flexibility.

Design structure: The structural design of the caster will also have an impact on its flexibility. For example, the radius, width, shape and connection of the caster will affect its flexibility.

Load Weight: Loads have a direct impact on the flexibility of casters. Heavier loads may limit the flexibility of the caster and make it difficult to rotate freely.

Ground conditions: The friction and resistance of casters on different surfaces can also affect their flexibility. For example, rough ground may increase the friction of the caster and reduce its flexibility.

Single ball bearings and double ball bearings are flexible and suitable for quiet environment; roller bearings have high load bearing capacity but general flexibility.
