4 Inch Heavy Duty Casters Wheels, Industrial Grade Polyurethane Casters Set o

Solid Polyurethane Casters:'s 4 inch heavy-duty industrial casters are made by combining polyurethane and polypropylene through hot pressing technology. The polypropylene hub provides strength and stability, while the polyurethane offers excellent rolling performance and traction, Ideal for outdoor use and transportation of heavy equipment and items Heavy Duty Casters:'s Industrial casters wheels top plate is made of stamped carbon steel, combined with a sturdy polypropylene hub and shock-absorbing polyurethane tires, with the ability to withstand strong vertical impact forces. Each caster wheel can support up to 625 pounds, and a set of 4 wheels can handle up to 2500 pounds Dual Ball Bearings: Our heavy-duty industrial-grade polyurethane casters feature two precision ball bearings, which are quieter, more load-bearing, and have a longer service life compared to conventional bearings.

Paired with polyurethane wheels, these casters ensure smooth and quiet operation over an extended period, are resistant to damage, and will not scratch the floor Flexibility: Industrial-grade polyurethane casters have high elasticity, effectively absorbing shocks and vibrations. This means that even on uneven surfaces, the casters can reduce the impact of vibrations on objects, protecting cargo from damage. Additionally, they are lighter than metal wheels, making them easier to move and operate. Their lightweight nature reduces the burden on operators while enhancing overall flexibility Wide Application: casters wheels are ideal for clean room environments that are frequently exposed to large amounts of moisture.

The solid polyurethane wheels can withstand temperatures ranging from 14°F to +176°F. If your application involves washing, humidity, moisture, chemicals, steam cleaning, or any situation involving dampness, these casters are your ideal choice.
