Product details
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
