Cylindrical Roller Bearing:N310

Description

Basic Parameters

The N310 cylindrical roller bearing is a single-row, separable design engineered for high radial load capacity and moderate-speed applications. With a bore diameter of 50 mm, outer diameter of 110 mm, and width of 27 mm, it features a cylindrical inner ring with two integral flanges and a flange-less outer ring, allowing bidirectional axial displacement to accommodate thermal expansion or misalignment. The bearing incorporates precision-machined cylindrical rollers for efficient line-contact load distribution, delivering a basic dynamic load rating (Cr) of 87–97 kN and static load rating (C0r) of 86–93 kN, depending on the manufacturer’s design enhancements. Standard chamfer dimensions (rmin = 2 mm) ensure compatibility with typical mounting shoulders. Operational limits include a grease-lubricated speed of 5,600–6,700 rpm and oil-lubricated speed up to 7,500–8,000 rpm, supported by its low-friction cage design (often non-metallic for reduced heat generation). Weighing approximately 1.1 kg, this bearing is widely used in industrial machinery such as gearboxes, pumps, and motors, leveraging its separable structure for easy installation and interchangeability of components. Key design attributes—high radial rigidity, axial flexibility, and robust roller guidance—make it ideal for heavy-duty scenarios requiring reliable radial load management.

Product Application

The N310 cylindrical roller bearing is ideally suited for industrial machinery requiring robust radial load capacity and moderate-speed operation, leveraging its separable design and axial flexibility to address common mechanical challenges. In **gearboxes** and **industrial motors**, its high radial rigidity stabilizes rotating shafts under heavy torque loads, while the two integral inner ring flanges enable controlled bidirectional axial movement to compensate for thermal expansion or minor misalignments in drivetrain systems. The bearing’s efficient line-contact roller design reduces stress concentrations, making it a preferred choice for **pumps** and **compressors** where consistent load distribution minimizes wear in fluid-handling equipment.
