What is the significance of the two-row design in this bearing?


The two-row design allows for improved load distribution, enabling the bearing to handle higher loads more effectively, which is especially beneficial in dynamic applications where stability is crucial.

How does the static load rating impact the selection of this bearing?


A higher static load rating signifies greater resistance to permanent deformation under load, ensuring the bearing can maintain integrity during applications that exert load when stationary.

What maintenance requirements are recommended for optimal performance?


Routine inspections and lubrication according to application speeds ensure smooth operation and prolong the bearing's lifespan. Regular checks for wear can prevent premature failure in high-load situations.

Drawn Cup Needle Roller Bearings


INA from Schaeffler drawn cup needle roller bearings with open ends and closed ends are bearings with a small radial section height. They comprise thin-walled, drawn cup outer rings and needle roller and cage assemblies which together form a complete unit.;Most the bearings are of a single row design and do not have a lubrication hole. Double row designs have a lubrication hole and the suffix ZW.

Features and Benefits


• Lower operating costs;• Reduced maintenance due to improved lubrication;• Lower heat generation;• Less noise

Product Application Information


These bearings allow the design of compact and easy‑to‑fit bearing arrangements with high radial load carrying capacity.;Drawn cup needle roller bearings require a hardened and ground bearing raceway on the shaft.

Suffixes


2RS - Contact seals on both sides;RS - Contact seal on one side;ZW - Double row design, with lubrication hole
