• 5/8 inch (15.88mm) carbon steel ball, screw mounted design with two 4.2mm mounting holes spaced 39mm apart — a standard configuration for quick and secure attachment to most industrial equipment, workbenches, and custom fixtures.
• 33lbs (15kg) load capacity per unit — reliably supports a wide range of medium-heavy applications, from factory conveyor systems to workshop material handling. Combine multiple units to distribute heavier loads across your equipment.
• Durable carbon steel construction with zinc plating finish — engineered for corrosion resistance, excellent rust prevention, and long-lasting performance in demanding industrial environments, including dusty and humid workshops.
• Versatile across industrial and daily scenarios — ideal for conveyor lines, feeding systems, processing machinery, and packaging equipment. Also perfect for DIY home projects requiring smooth movement of cabinets, boxes, pallets, sliding beds, and sliding doors.
• Pro-tip: Add a small amount of lubricant before first use — this simple step significantly enhances rolling performance and extends bearing lifespan. Each unit rotates 360° omnidirectionally, ensuring effortless movement of heavy objects in any direction.
