SS 3303 2RS LDI Angular Contact Ball Bearing 17x47x22,2

Application of SS 3303 2RS Angular Contact Ball Bearing

The SS 3303 2RS LDI 17x47x22,2 is a double-row angular contact ball bearing designed to support combined radial and axial loads simultaneously. Thanks to its two-row configuration, it provides higher rigidity and improved load capacity compared to a standard single-row deep groove ball bearing.

This bearing is widely used in industrial machinery, automotive systems, pumps, gearboxes, drive units and other mechanical assemblies where stable shaft positioning is required. It can operate as a standalone component or be installed within a bearing housing to create a compact and reliable bearing unit.

The 17x47x22,2 dimensions make it suitable for medium-duty applications where both axial and radial forces occur in dynamic operating conditions.

Advantages of 2RS Sealing and SS Stainless Steel Version

The 2RS designation indicates double-sided rubber seals that protect the internal components from dust, moisture and contaminants. This significantly increases service life and reduces maintenance requirements in demanding industrial applications.

The SS version is manufactured from stainless steel, offering enhanced corrosion resistance. This makes the bearing suitable for environments exposed to humidity, water or aggressive agents, while maintaining high durability and operational reliability.

Key benefits:

• High durability under combined loads

• Double-row design for increased rigidity

• Effective sealing with 2RS protection

• Corrosion resistance thanks to stainless steel construction

• Stable performance at medium and higher rotational speeds

FAQ - Frequently Asked Questions

What is the difference between angular contact and deep groove ball bearings?
Angular contact ball bearings are designed to support higher axial loads due to their contact angle, while deep groove ball bearings are primarily optimized for radial loads.

Can SS 3303 2RS handle axial loads in both directions?
Yes, the double-row configuration allows it to support axial loads in both directions along with radial loads.

When should stainless steel bearings be used?
Stainless steel bearings are recommended in environments with moisture, corrosion risk or exposure to aggressive substances.

Does the bearing require additional lubrication?
No. The 2RS sealed version is pre-lubricated and ready for installation in most standard industrial applications.
