Special Dimension Deep Groove Ball Bearing
22.2 mm Bore × 56 mm OD × 21 mm Width · 2RS · C3 · In Stock · Compatibility Verification Available
Send us your original bearing number, dimensions, photo, or sample — we'll help confirm the correct replacement before you order.
The 62322.2-2RS C3 is a special-dimension deep groove ball bearing with a 22.2 mm bore, 56 mm outside diameter, and 21 mm width.
The bearing uses double rubber seals (2RS) and C3 internal clearance, making it suitable for applications where this specific dimensional and clearance configuration is required.
This size is commonly listed for automotive alternator applications, including Bosch 12V and 24V alternators. Public bearing references also list Bosch and NTN part numbers associated with the same 22.2 × 56 × 21 mm size.
Our 62322.2-2RS C3 is an independently manufactured replacement bearing. It is not manufactured, affiliated with, or endorsed by NTN or Bosch. Brand and OEM numbers are referenced only for identification and compatibility purposes.

The 62322.2-2RS C3 is a special-dimension deep groove ball bearing measuring 22.2 × 56 × 21 mm.
Its 22.2 mm bore is not a common size in the standard 62/63-series bearing range, which is one reason this bearing is often specified by its exact dimensions or automotive cross-reference rather than by a common standard bearing number.
The 2RS sealing arrangement helps protect the bearing from external contaminants and retain internal lubricant.
The C3 clearance provides greater internal radial clearance than normal clearance. Whether C3 is appropriate depends on the shaft and housing fits, operating temperature, speed, and application conditions.

We'll check the dimensions, configuration, and cross-reference before shipment.
Don't have all the information? Send us whatever you have.
A photo, partial dimensions, or an old bearing sample may be enough for us to start the identification.
What does 62322.2-2RS C3 mean?
62322.2 identifies the bearing size configuration, while 2RS indicates double rubber seals and C3 indicates increased internal radial clearance compared with normal clearance.
Is this bearing used in Bosch alternators?
Yes. Public automotive bearing references list 62322.2-2RS C3 for Bosch 12V and 24V alternators, including several Bosch part numbers.
Can this bearing replace the NTN TM-623/22LLUA/22.2C3?
It may be a compatible replacement when the dimensions and configuration match.
The NTN number is a brand-specific designation, so the original bearing number, dimensions, and application should be checked before replacement.
Is this bearing suitable for high-temperature applications?
C3 provides increased internal clearance, which can help accommodate thermal expansion in suitable applications. However, the correct clearance depends on the complete bearing arrangement and operating conditions.
What if I don't know the exact bearing number?
Send us the old bearing, a photo, or the dimensions you can measure.
You do not need to know the exact replacement model before contacting us.
Finding a replacement for a 22.2 mm bore bearing can be difficult because the size is not a common standard replacement in many distributor catalogs.
