FAQ
How effective is the shock absorption on LD-426 rubber casters?
The LD-426 elastic rubber caster provides excellent shock absorption thanks to its high-quality natural rubber compound with 70-85 Shore A hardness. The rubber tire compresses under load and absorbs impact from uneven floors, bumps, and debris, reducing vibration transfer to the load by up to 40% compared to hard nylon or polyurethane wheels. This makes them ideal for transporting fragile or sensitive equipment.
Are these rubber casters quiet on hard floors?
Yes, the LD-426 series is designed for quiet operation. The elastic rubber tread absorbs sound and vibration, resulting in significantly lower noise levels compared to hard plastic or metal wheels. On tile, hardwood, or concrete floors, these casters roll with minimal noise, making them perfect for office, hospital, and retail environments where noise reduction is important.
What types of floors are these rubber casters suitable for?
LD-426 rubber casters are suitable for a wide variety of floor surfaces including concrete, tile, hardwood, laminate, vinyl, linoleum, and epoxy-coated floors. The non-marking rubber formulation ensures no scuffs or black marks are left on light-colored flooring. For extremely rough or outdoor surfaces, we recommend checking the specific load capacity and considering our heavy-duty caster options.
How is the load capacity determined and what does it mean per caster?
Load capacity ratings for LD-426 casters are tested per individual caster under controlled conditions, ranging from 50kg for the 75mm model to 350kg for the 200mm model. When calculating total cart capacity, multiply the per-caster rating by the number of casters, then apply a safety factor of 25-30% to account for uneven weight distribution and dynamic loads. For example, four 100kg casters would safely support approximately 280-300kg of total load on a typical cart.
