4 inch Industrial Trolley 100mm Heavy Duty Cast Iron Core PU Polyurethane Swivel Caster Wheel with Brake

This heavy‑duty 4‑inch red iron‑core PU swivel caster is engineered for industrial heavy‑load transportation. The wheel adopts solid cast iron inner core wrapped with high‑elastic red polyurethane outer tread, paired with thick stamped galvanized steel swivel bracket. It combines high load‑bearing capacity, outstanding wear resistance, quiet rolling and floor‑protecting performance. Suitable for industrial trolleys, warehouse handling carts, workshop mobile equipment, logistics machinery and other heavy‑duty mobile devices. Brake‑equipped swivel models and fixed‑bracket versions are available to meet diverse usage demands.

• Solid Iron‑Core Wheel for Heavy‑Duty Use
  Built‑in solid iron core brings superior mechanical strength, strong impact resistance and anti‑deformation performance. It can sustain heavy‑weight pressure for long‑term operation, avoiding the crack or deformation issues that commonly happen with plastic‑core wheels under heavy loads. Greatly extends service life under frequent industrial working conditions.

• High‑Quality Red PU Polyurethane Tread
  The outer red PU tread possesses excellent abrasion resistance, tear resistance and compression resistance. It rolls smoothly with low noise during movement. The soft PU surface will not scratch, scuff or leave black marks on concrete floors, epoxy floors and tile surfaces. It performs stably under indoor normal‑temperature working environment.

• Thick Galvanized Steel Swivel Bracket Assembly
  Made of high‑thickness stamped steel sheet with hot‑dip galvanized anti‑rust treatment, effectively preventing oxidation and rust. Precision swivel raceway enables flexible 360‑degree free rotation, realizing easy direction switching when pushing or pulling goods. Standard flat mounting plate with pre‑fabricated mounting holes for quick, stable installation onto equipment base. Total height 144mm, mounting plate size 100 mm *100 mm, consistent with drawing dimension.

• Reliable Industrial‑Grade Construction
  Adopts high‑strength bolt‑and‑nut axle assembly, firm connection, not easy to loose during long‑time rolling. Multiple optional configurations: total lock brake, directional brake, fixed non‑swivel bracket. Supports mass‑production order for factory‑level procurement.

• Cost‑Effective Heavy‑Load Solution
  Balances heavy‑load performance and competitive cost. Ideal selection for material‑handling trolleys, warehouse carts and workshop mobile equipment. Supports sample testing before bulk order.

Widely deployed in factory production workshops, storage warehouses, logistics transit stations and processing plants. Perfect fit for heavy‑load hand trolleys, mobile workbenches, storage cabinets and various mobile industrial equipment. Well suited for customers requiring high load capacity, long service life and floor‑protection performance.
