Why do industrial casters generally have more rolling resistance than domestic casters?

Industrial casters usually have a higher rolling resistance than domestic casters.This is mainly due to several reasons:

Carrying capacity:Industrial casters designed to carry heavier loads.As a result they are usually heavier and more robust in size and construction.to provide adequate strength and stability.This design, while increasing the carrying capacity of  But it also increases resistance when rolling.

Material and bearings:Industrial casters may use different materials and bearing systems.These materials and bearings may provide more durability and stability when rolling.But it also increases rolling resistance.For example.Although the high-precision ball bearings run smoothly and flexibly, the  However, it may not reduce rolling resistance as much as some lightweight bearings.

Environmental Adaptation:Industrial casters need to be adapted to a variety of different working environments, the  This includes rough ground, chemical attack or extreme temperature conditions.These environments require casters with greater durability and adaptability.It may be possible to achieve these characteristics by increasing rolling resistance.

Design and use:Domestic casters are usually designed for less frequent use and lighter loads.They are therefore designed to be more lightweight and economical.In comparison.Industrial casters need to withstand continuous and intense use.They are therefore designed with a greater focus on durability and performance.Instead of minimizing rolling resistance.

In summary.Industrial casters are designed with a focus on load carrying capacity, durability and environmental adaptability.While these features increase the versatility and reliability of casters, the  But it also results in greater rolling resistance compared to household casters.
