The NNTR5013065 is a heavy-duty double-row track roller bearing. With an inner diameter of 50mm, an outer diameter of 130mm, and a width of 65mm, it is designed to withstand extremely high radial loads, moderate axial loads, and heavy impact conditions.

Utilizing a cageless full roll configuration, it significantly improves load-carrying capacity and service life compared to standard roller bearings. The convex outer ring effectively compensates for slight misalignment and edge stresses, ensuring stable rolling performance.

This bearing features high rigidity, low friction, and stable operation, and is widely used in heavy-duty conveyor systems, lifting platforms, construction machinery, metallurgical equipment, automated production lines, tracked mechanisms, and other industrial applications. We provide reliable OEM and customization services and maintain strict quality control to meet the needs of global industrial applications.

NNTR series bearings are heavy-duty roller bearings with thick outer ring, converging or curved outer diameters, and a full complement of cylindrical rollers. These bearings are primarily used in sliding tracks on heavy machinery, such as conveyor tracks, where they can roll directly on the raceways and withstand heavy loads and shocks. NNTR bearings typically feature epoxy guides and sparse seals, making them particularly suitable for large-scale transmission equipment.
