Medium Duty Casters Wheels

A: This medium duty caster wheel has a load capacity of 50-60 kg per caster. For equipment with four casters, the total capacity is 200-240 kg. However, please note that the effective load per caster should be calculated as Total Load ÷ 3 (allowing for uneven weight distribution) rather than Total Load ÷ 4.

A: This caster is available with three mounting options: Hollow Kingpin - uses a hollow rivet or pin for permanent, secure attachment - ideal for shopping carts and equipment where casters are expected to remain attached for the life of the equipment; Stem mounting - uses a metal stem that inserts into a socket on the equipment - offering quick installation and easy replacement; and Top plate mounting - uses a flat metal plate with bolt holes for secure attachment. Please specify your preferred mounting type when ordering.

A: TPR (Thermoplastic Rubber) is widely used for medium-duty casters because: Quiet operation - soft tread significantly reduces rolling noise; Floor protection - non-marking material protects sensitive floors; Good rolling efficiency - smooth movement with reasonable rolling resistance; Durability - withstands daily use in workshop and commercial environments. For applications where noise and floor protection are priorities, TPR is often the preferred choice.

A: This caster series is available with five wheel material options: TPR - quiet, non-marking, floor-protective (standard); PP (Polypropylene) - lightweight and chemical-resistant; Nylon - superior wear resistance and impact strength; PU (Polyurethane) - excellent durability and oil/grease resistance; and Rubber - superior shock absorption for uneven surfaces. Choose based on your application requirements and floor conditions.

A: A total lock brake locks both the wheel (preventing rolling) and the swivel mechanism (preventing rotation) simultaneously. This is important for: Stationary security - equipment remains completely fixed during loading or use; Safety - prevents unexpected movement on sloping surfaces; Stability - ensures equipment stays in position during operations. This brake type is essential for applications where equipment must remain completely secure when stationary.

A: This caster is available in 3-inch and 4-inch diameters. The 3-inch option (featured here) offers a compact size with a 102mm load height. The 4-inch option provides better rolling efficiency over floor joints and a higher load height. Choose based on your equipment design and load height requirements.

A: This caster is suitable for: Medium-duty carts - service carts, utility carts, and platform trucks; Industrial equipment - workshop equipment and machinery stands; Commercial equipment - retail fixtures and display units; Material handling - light to medium material handling equipment; Workstations - mobile workstations and assembly stations.

A: Hollow Kingpin uses a hollow rivet or pin for permanent, secure attachment - ideal for equipment where casters are expected to remain installed for the life of the equipment. Stem mounting uses a metal stem inserted into a socket - offering quick installation and easy replacement, ideal for furniture and light equipment. Top plate mounting uses a flat metal plate bolted to the equipment - providing secure attachment, suitable for applications where the caster is expected to remain installed. Choose based on your equipment design and maintenance requirements.

A: A total lock brake locks both the wheel and the swivel mechanism, completely fixing the caster in position. A side brake locks only the wheel - the swivel remains free to rotate, allowing directional adjustment even when stationary. Choose total lock brake for complete stationary security on sloping surfaces or where equipment must remain completely fixed; choose side brake for applications where directional flexibility while locked is beneficial.
