Core Product Advantages
-
High-Strength Solid PP Wheel
The wheel body adopts thickened solid polypropylene material, with strong impact resistance, wear resistance and compression resistance. The matte off-white surface is stain-resistant and easy to clean, suitable for food processing workshops, medical clean rooms, supermarkets and other high-cleanliness scenarios. It will not scratch epoxy floors, ceramic tiles or cement ground.
-
Dual-Bearing Silent Rolling System
Built-in 6001 double ball bearings greatly reduce rolling friction. The wheel rotates flexibly and quietly without jamming even under full rated load, saving labor for daily pushing and moving.
-
Galvanized Thickened Steel Bracket
The bracket is stamped from thick steel plate with surface galvanizing anti-rust treatment, effectively isolating oxidation and slight corrosive liquid. The swivel head adopts multi-ball rotary design to realize 360° free steering, flexible to change moving directions.
-
Universal Square Mounting Plate
Standard square top mounting plate with unified hole spacing specification, simple for installation, disassembly and replacement on most standard transport equipment frames. Matching brake and fixed rigid versions are available for full set collocation.
