Product Description

The SKF Angular Contact Ball Bearing, model 3304/5304 (MPN 3304 A C3), is a metric single bearing with a double-row, 30° contact angle, open design, ABEC 1 tolerance, and steel cage. It features a 20 mm bore and is supplied as a not matched/single bearing unit.

Frequently Asked Questions

What is the SKF 3304 A C3 angular contact ball bearing used for?

The SKF 3304 A C3 double-row angular contact ball bearing handles combined radial and axial loads in industrial machinery. Common applications include pumps, compressors, gearboxes, and electric motors where high-speed operation and rigidity are required. Its 30° contact angle and steel cage suit moderate-speed, moderate-load environments.

What are the specifications of the SKF 3304 A C3 bearing?

The SKF 3304 A C3 is a metric double-row angular contact ball bearing with a 20 mm bore, 30° contact angle, open design, ABEC 1 tolerance, and steel cage. It is a single bearing (not matched), with bearing industry number 3304/5304. The C3 internal clearance allows for thermal expansion during operation.

Where to buy SKF 3304 A C3 bearings worldwide?

3G Electric supplies the SKF 3304 A C3 bearing worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact our team for pricing and lead time. We source genuine SKF bearings to meet your application requirements.

How to select the correct SKF angular contact bearing for an application?

To select the correct SKF angular contact bearing, verify the required bore size (20 mm for 3304 A C3), load type (radial vs. axial), speed, and operating temperature. The 30° contact angle suits moderate axial loads. Confirm the C3 clearance if thermal expansion is expected. Always match the bearing series to the housing and shaft fit.

Used in

Common applications for SKF
Heavy machinery gearboxes — SKF spherical roller bearings (e.g., 24056 CCK30/W33) for high radial load capacity
