Ball bearings
Deep Groove Ball Bearings
The default choice for a rotating shaft. An uninterrupted deep raceway carries radial load, both axial directions and the small misalignment every real machine frame has.

- Class
- P6 / P5
Design
One envelope, every variant.
Every batch is measured on the finished part, and the measurement file travels with the goods. Send a designation, a drawing or a photo of the failed part and an engineer will answer with a lead time and a price, usually inside 48 hours.
- Sealed, shielded or openZZ for dust, 2RS for washdown and food areas, open where relubrication is planned.
- Checked for noiseVibration and sound measured on a dedicated stand for electric-motor duty.
- Standard or C3 clearanceC3 where the housing runs hot, CN where fit and preload are already tight.
- One envelope, many variantsA sealed part drops into the same housing as the open one, without a drawing change.

Where it is used
Common applicationsElectric motors
Radial and axial location of the rotor, quiet enough for machine-tool duty.
Pumps
Sealed variants for coolant and light chemical service.
Gearbox shafts
Supporting the intermediate shaft where the helical gear adds axial load.
Fans and blowers
Long duty cycles at moderate load, where grease life sets the service interval.
Send the part number.
We will send the answer.
A designation, a drawing, or a photo of the failed part is enough to start. Technical questions reach an engineer, not a mailbox.
