NSK Nup2218em 2219em 2220em Cylindrical Roller Bearing

Optimale Leistung bei Anwendungen mit hoher Belastung und hohen Drehzahlen

These cylindrical roller bearings excel in environments where radial loads are dominant, such as in gearboxes and electric motors. The 180*225*22mm specification (for the 6836 model) provides a balance of size and load capacity, making it suitable for medium to large industrial equipment operating at moderate speeds. Their design allows for efficient heat dissipation, reducing the risk of overheating in continuous-operation scenarios like conveyor systems and hydraulic pumps.

Critical Engineering Features for Reliable Operation

The bearing steel material offers high surface hardness, directly contributing to wear resistance and extended service life—key factors in minimizing downtime. Precision classes ranging from P0 to P2 (ABEC1 to ABEC9) ensure dimensional accuracy, allowing for interchangeable installation with original NSK components. This level of precision is crucial in applications where shaft and housing tolerances are tightly controlled, such as in precision machining equipment. Additionally, the cylindrical roller design distributes load evenly across the raceway, reducing stress concentrations and enhancing dynamic load handling capabilities.

Gesamtbetriebskosten: Warum hochwertige Lager wichtig sind

Choosing a bearing with the right material and precision class directly impacts long-term costs. Inferior bearings may initially cost less but often lead to frequent replacements, production halts, and potential damage to adjacent components. The ISO 9001:2008 compliant production process for these cylindrical roller bearings ensures consistent quality, reducing the likelihood of premature failure. By selecting bearings with appropriate precision levels (P5 or higher for high-speed applications), operators can lower maintenance requirements and extend equipment lifespan, ultimately reducing total operational expenses.
