NU316‑ECM Single‑Row Cylindrical Roller Bearing 80×170×39mm Machined Brass Cage For Gearbox

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.

• Ultra‑high radial load capacity for heavy‑duty industrial applications
• NU‑type structure allows inner‑ring axial displacement to absorb shaft thermal expansion
• Solid machined brass cage features excellent anti‑deformation performance at high temperature
• Optimized roller profile for low‑friction stable continuous heavy‑load rotation
• Suitable for heavy‑duty gearbox, reducer and industrial transmission assemblies
• Custom design available (clearance grade, OEM laser marking)

This bearing is widely used in:

• Heavy‑duty gear reducer input & output shafts
• Mining machinery intermediate transmission units
• Metallurgical plant rotary supporting assemblies
• Large‑size fan main shaft rotating parts
• Industrial equipment aftermarket replacement projects

• 25+ years experience in industrial bearing manufacturing
• Exported to 50+ countries worldwide
