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.
