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

How does the material choice affect the bearing's performance?


The steel construction provides high strength and wear resistance, allowing the bearing to withstand substantial loads and extend its service life in rigorous conditions.

What type of lubrication is recommended for optimal performance?


Using oil lubrication can achieve the maximum speed of 8,600 rpm, whereas grease should be used when expecting a maximum speed of 5,200 rpm for prolonged efficiency.

Are there specific installation considerations to keep in mind?


Correct alignment and fitting are essential

ensure the bearing is placed in a manner that allows for unhindered rotation during operation for optimal performance.
