| High Light | heavy duty polyurethane wheel caster ，aluminum core PU caster ，304 stainless steel caster bracket | ||
These heavy duty caster wheels feature a polyurethane (PU) tread bonded to a solid aluminum core, providing superior durability, abrasion resistance, and high load capacity. The aluminum core enhances wheel strength while reducing overall weight, and the PU tread offers quiet rolling, excellent floor protection, and smooth movement across diverse floor surfaces. The bracket and fork are made of 304 stainless steel, giving excellent corrosion resistance and longevity in harsh or wet environments. Precision bearings ensure smooth rotation and low rolling resistance.
Function
Designed to provide stable support and ease of movement for heavy carts, industrial trolleys, equipment platforms, and machinery, these caster wheels enhance mobility and handling efficiency. The PU tread reduces vibration and noise, while the 360° swivel design allows flexible direction changes with minimal effort. Precision bearings support effortless rotation, reducing fatigue during frequent industrial use.
These polyurethane wheel caster wheels with aluminum core and 304 stainless steel bracket are ideal for industrial and commercial environments such as warehouses, factories, logistics centers, workshops, equipment racks, assembly lines, and wet or corrosive areas. Their corrosion-resistant construction and smooth rolling make them suitable for heavy handling and repeated use in demanding conditions
High Load Capacity & Lightweight – Aluminum core increases structural strength while keeping weight manageable. Aluminum wheel rim also for oxidation resistance, fast heat release, and high loading capacity.
Superior Abrasion Resistance –Cast PU tread resists wear and tear on rough floors. Cast PU is a very wear resistant material.
Floor Protection & Quiet Rolling – Polyurethane prevents scuffing and reduces noise.
Corrosion-Resistant Stainless Steel Bracket – 304 stainless steel construction extends service life in wet or corrosive environments. All fittings are SUS 304 stainless steel, including top plate, fork, rivets, swivel ball raceway (swivel bearing), rolling balls in the ball raceway, mounting kingpin, bolt and nut, all of them are stainless steel 304 material.
Smooth Movement & Efficient Handling – Precision bearings reduce rolling resistance and improve maneuverability.
