1. Product Overview The NU316‑ECM is a single‑row open cylindrical roller bearing with solid machined brass cage, designed for heavy‑duty gearbox and industrial transmission assemblies. NU‑type construction allows inner‑ring axial displacement to compensate shaft thermal expansion, delivering large radial load capacity. It is widely used for heavy gear reducers and industrial machinery where high radial‑load capacity is required. Get a quote within 24 hours for your project 2
