Material Composition & Construction
This wheel is constructed from a high-strength, solid polyurethane (PU) compound with a 65 Shore D hardness. It is available with either a plain bearing or a roller bearing core, providing flexibility for different load and speed requirements. The solid construction ensures maximum durability and resistance to deformation under heavy loads.
Key Performance Features
Floor & Surface Protection: Non-marking and non-staining, guaranteeing excellent preservation of sensitive flooring.
Operational Efficiency: Engineered for low-noise operation and low rolling resistance, reducing operator effort and creating a quieter work environment.
Exceptional Durability: Offers high resistance to abrasion, cuts, and tear propagation, ensuring a long service life in demanding conditions.
Chemical Resistance: Provides high resistance to a wide range of aggressive substances, including oils, greases, and solvents.
Technical Specifications
Material: High-strength Polyurethane (PU)
Hardness: 65 Shore D
Operating Temperature: -40°C to +80°C (temporarily up to +90°C)
Note: Load capacity is reduced at ambient temperatures above +50°C.
Application Scenarios
This wheel is ideal for medium to heavy-duty industrial applications where durability and floor protection are paramount. Typical use cases include:
