Heavy Duty Casters for Demanding Tasks：Engineered with reinforced steel frames and precision ball bearings, each 5 inch heavy duty caster effortlessly supports up to 9900 LBS. Built to stabilize heavy machinery, tool carts, warehouse racks, and more—resistant to deformation even under prolonged stress Multi-Surface Mastery：Industrial grade heavy duty casters with high-density nylon rollers with anti-slip treads ensure whisper-quiet movement and superior grip on wood, tile, carpet, or rugged terrain. Weatherproof and abrasion-resistant, ideal for indoor/outdoor durability Universal Compatibility: Heavy duty casters wheels seamlessly integrates with hand trucks, industrial equipment, furniture, storage systems, and toolboxes. Perfect for factories, warehouses, garages, or outdoor projects—simplify heavy lifting across any environment 360° Smooth Swivel & Instant Lock Mechanism: Nefish heavy duty casters with dual-ball-bearing construction enables agile steering in tight spaces. Integrated one-touch brake locks wheels instantly, preventing accidental shifts and ensuring stationary stability Anti-Tip Design with Ultra-Low Center of Gravity：Widened plate and low-profile wheels minimize tilt risks by 50% versus traditional casters. Ensures safe transport on uneven surfaces or during sharp turns, even with top-heavy loads Overall, low gravity casters are essential in a range of equipment and machinery, providing smooth and stable movement for improved performance and safety. Choosing the right low gravity caster for your needs ensures that your equipment can move smoothly and safely without tipping over or becoming unstable.Low gravity casters are specifically designed for equipment and machinery with a low centre of gravity. This means the equipment is less likely to tip over or become unstable during movement. Low gravity casters are typically made with high-quality materials such as steel or aluminum, and they feature a low profile design that allows them to fit into tight spaces.
