Technical Specifiacations

Superior Material Composition: Our Pro-Series casters utilize a tri-layer material design. The PA6 Nylon frame provides the structural integrity needed for industrial loads. The Polypropylene (PP) core offers lightweight durability, while the TPE (Thermoplastic Elastomer) tread provides a soft-touch, non-marking grip that excels in shock absorption.
Smooth Motion Technology: Equipped with internal precision ball bearings, these wheels minimize friction and rotational resistance. Whether it’s a 75mm medical cart or a 125mm industrial robot base, the swivel mechanism remains fluid under maximum load.
Extreme Environment Ready: Tested to operate flawlessly in temperatures ranging from -30°C to +80°C. Ideal for cold storage, sterilization environments, and outdoor industrial use.

Frequently Asked Questions

Q: What materials are used in the construction of these casters?
A: Our Pro-Series casters feature a high-load capacity Nylon (PA6) main frame for chemical and wear resistance. The wheel core is made of Polypropylene (PP), and the tread is crafted from ultra-quiet TPE for superior shock absorption.

Q: What is the operating temperature range for these wheels?
A: These casters are designed to perform reliably in extreme environments, with an operating temperature range of -30°C to +80°C.

Q: Are these casters compliant with international safety standards?
A: Yes, all sizes in this series (75mm, 100mm, and 125mm) are fully compliant with the EN12531 standard for casters and wheels.

Q: What are the load capacities for the different sizes?
A: The 75mm (3″) model supports up to 60KG dynamic load, the 100mm (4″) model supports 80KG, and the 125mm (5″) model is rated for 100KG dynamic load.

Q: Do you provide CAD or 3D files for engineering integration?
A: Yes, we offer technical drawings and can provide CAD files (STP/STEP) upon request to assist with your robotics or equipment design process.
