The N310ECP SKF is a high‑capacity single‑row cylindrical roller bearing with an optimized EC internal design and polyamide cage, developed for heavy radial‑load, high‑speed industrial applications. Its separable structure allows independent installation of inner and outer rings, delivering high rigidity, low friction and excellent shock resistance for precision transmission systems.
Dimensional parameters conform to ISO 582‑1 standards: inner diameter 50 mm, outer diameter 110 mm, width 27 mm, chamfer 1.5×45°, tolerance grade P0, normal radial clearance CN. The open‑type structure supports convenient lubrication and heat dissipation for continuous high‑speed operation.
Inner rings, outer rings and cylindrical rollers are produced from high‑purity 100Cr6 vacuum‑refined bearing steel, quenched to HRC 61–63 with superior wear resistance, contact fatigue strength and dimensional stability. The P polyamide cage (glass‑fiber reinforced) features lightweight structure, low noise and high temperature resistance, ensuring stable roller guidance under heavy‑load rotation.
Key manufacturing processes include precision hot forging, high‑precision CNC turning, controlled‑atmosphere quenching‑tempering, raceway grinding and superfinishing. Forging optimizes metal fiber distribution; heat treatment eliminates residual stress; superfinishing achieves ultra‑fine surface quality to reduce friction loss and improve running stability.
Calculated per ISO 281 standard, the N310ECP SKF has a rated L10 service life of 68 000 hours under standard radial load, steady speed and proper lubrication. Service life is mainly affected by applied load magnitude, operating speed, shaft alignment, lubrication quality and working temperature.
This cylindrical roller bearing is widely used in machine tool spindles, wind turbine gearboxes, heavy‑duty gear units, electric motors, construction machinery and railway transmission systems. Its high radial‑load capacity and separable design enable compact assembly and maintenance for high‑power rotating equipment.
For routine maintenance, re‑lubricate every 300 operating hours with high‑speed lithium‑based extreme‑pressure grease, with filling quantity 2.0–2.5 g. Keep bearing surfaces free of dust and moisture; regularly check running noise, temperature and roller clearance, replacing components upon abnormal wear.
Before installation, clean mating shafts and housings and verify H7/h6 tolerance. Adopt press‑fit assembly without hammer impact, control coaxiality within 0.02 mm/m and follow standard tightening torque. Conduct no‑load trial run post‑installation to confirm smooth rotation and stable performance.
