About Heavy Duty Castor
A vertically integrated Chinese manufacturer specializing in mid-to-high-end industrial casters and leveling mounts — where precision manufacturing meets material science innovation.
A Chinese Manufacturer the World Trusts
Heavy Duty Castor is a China-based manufacturer with over 25 years of experience in designing, engineering, and producing industrial-grade caster wheels and adjustable leveling mounts. Our 12,000 m² production facility houses advanced forging, CNC machining, polyurethane casting, and automated assembly lines — all under one roof.
We are not a trading company. Every product we ship is manufactured, tested, and certified in our own factory, giving us complete control over quality, cost, and delivery timelines. From raw steel to finished caster, the entire production process is managed in-house.
Today we serve distributors, OEM cart builders, and industrial buyers in over 60 countries, producing more than 300,000 caster units per month across hundreds of configurations.
Core Philosophy
Dedicated to the R&D and production of mid-to-high-end casters and leveling mounts, we integrate precision manufacturing with material science innovation — applying military-grade standards to ensure load-bearing performance and durability in every single product.
Material Innovation
We continuously research and develop new wheel compounds — from high-performance polyurethane formulations to advanced engineering thermoplastics — pushing the boundaries of load capacity and floor protection.
Precision Engineering
Every swivel rig, kingpinless assembly, and bearing housing is CNC-machined to tolerances that ensure smooth rotation, minimal wear, and consistent performance across production batches.
Military-Grade Standards
Our quality control processes are modeled after aerospace and military manufacturing standards — because industrial safety demands nothing less than absolute reliability under extreme conditions.
Corporate Vision
"Making load-bearing more reliable, making mobility more free."
We are deeply rooted in the industrial caster field, driving progress through material innovation and process iteration. Our vision is to become the core component supplier for intelligent material handling systems worldwide.
As global logistics evolves toward automation and smart factories, the demand for higher-performance caster systems grows exponentially. We position ourselves at the forefront of this transformation — not just as a parts supplier, but as an engineering partner that helps shape the future of industrial mobility.
Continuous Innovation
Annual R&D investment in new materials and structural designs.
Global Reach
FOB, CIF and DDP shipping to six continents.
Engineering Partners
Dedicated engineers for OEM and custom projects.
ISO 9001 Certified
Audited quality management system across all production.
Quality is Faith
Stamping precision is not merely a process parameter — it is the core expression of caster quality. From micro-structure to assembly accuracy, every detail determines rotational smoothness and durability. We transform process standards into our cultural DNA, building an unassailable competitive barrier.
Micro-Structure Control
Material grain structure analysis ensures wheel integrity under heavy cyclic loads.
Assembly Precision
Sub-millimeter tolerances on every rig and bearing seat guarantee smooth, vibration-free operation.
Extreme Temperature Rating
Products engineered and tested to perform reliably from -40°C to 150°C — deserts, cold chains, foundries.
Cultural DNA of Quality
Quality is not a department — it is embedded in every process, every decision, every product we ship.
Engineered to perform in extreme conditions: -40°C to 150°C
Whether it's a frozen cold-chain warehouse, a scorching steel mill, or a pharmaceutical cleanroom — our products are built to deliver stable, reliable performance when it matters most.
