Other versions of 309
The same size in another design – open, shielded, tapered bore.
2RS, 2Z or C3 – which to choose?
2RS (two rubber seals) keeps dust and moisture out but limits speed. 2Z (metal shields) does not touch the ring, so it runs faster and cooler but protects less. 2RZ is the compromise – a non-contact seal.
Choose C3 clearance when the bearing runs hot (electric motors, fans) or with a tight shaft fit. Normal clearance CN is enough for ordinary applications.
The dimensions of 309 are identical for every manufacturer, so the items in the table are interchangeable – just match the clearance and sealing.
