Updated on: 2nd Jun,2026

Looking for a Bearing Manufacturer?

BKZ Industry offers reliable solutions for all your bearing needs.

If you are a purchaser of cylindrical roller bearings, you may want to confirm the bearing size, check the bearing number, or see whether the bearing can fit your application.

That is why I put this cylindrical roller bearing size chart here. You can check common cylindrical roller bearing types, bearing numbers, bore diameter, outside diameter, width, load ratings, limiting speed, and other related dimensions.

This can help you compare sizes, check possible replacement models, and prepare your inquiry before purchasing.

Please note that this cylindrical roller bearing size chart is only for reference. For actual applications, you still need to confirm the bearing size, structure, clearance, precision, load capacity, and working conditions with the manufacturer before placing an order.

If you need to buy cylindrical roller bearings in bulk, you can contact BKZ Industry. With 15 years of bearing manufacturing experience, BKZ Industry can help you confirm the right bearing size, check equivalent models, and provide standard or customized cylindrical roller bearing solutions.

Now, let’s check the size chart in mm for single row, double row, and four-row cylindrical roller bearings.

Since the size chart is very long, you can press Ctrl + F on Windows or Cmd + F on Mac, then enter the bearing number or bearing size to find the model you need quickly.

Part 4. FAQS About Cylindrical Roller Bearing Size Chart

Q1. Can BKZ Industry offer equivalent cylindrical roller bearings for branded bearing numbers?

Yes. BKZ Industry can offer the equivalent cylindrical roller bearings for many branded bearing numbers. You can send us the bearing number, bearing size, drawing, or other available information. Our team will check and send quotation to you.

Q2. Can I buy a cylindrical roller bearing directly based on the size chart?

The size chart is only for reference, so we do not suggest buying directly based on size alone. Even if the bore diameter, outside diameter, and width are the same, the bearing may still be different in structure, internal clearance, cage material, precision, lubrication, load direction, and working speed. To avoid wrong selection, please contact BKZ Industry with your bearing number, size, drawing, or application details. We will help confirm the suitable bearing before quoting.

Q3. What are the differences between grease speed and oil speed for cylindrical roller bearings?

Grease speed and oil speed refer to the bearing limiting speed under different lubrication methods. Grease lubrication is easier to use and maintain, but the speed is usually lower. Oil lubrication can remove heat better, so the oil speed is usually higher. For actual selection, you still need to confirm the load, temperature, lubrication method, and working conditions.

Q4. What are the differences between NU, NJ, NUP, N, NF, RN, and RNU cylindrical roller bearings?

These codes mainly describe the rib structure and ring arrangement of cylindrical roller bearings. NU type has two ribs on the outer ring and no ribs on the inner ring. N type has two ribs on the inner ring and no ribs on the outer ring. NJ type has two ribs on the outer ring and one rib on the inner ring, while NF type has two ribs on the inner ring and one rib on the outer ring. NUP type has two ribs on the outer ring, one fixed rib on the inner ring, and one loose rib ring on the other side. RN type is a cylindrical roller bearing without an outer ring, while RNU type is a cylindrical roller bearing without an inner ring.

Q5. Why Is the bearing I am searching for not listed in the size chart?

There are many different cylindrical roller bearing types, sizes, and customized structures, so we cannot include every model in this size chart. If you cannot find the bearing number or size you need, you can contact BKZ Industry with the information you have. Our team will help you check the bearing size, confirm the structure, and send you a quotation.

Final Words

With this cylindrical roller bearing size chart, you can quickly check common bearing numbers, dimensions, load ratings, limiting speeds, and related technical data. However, the size chart is only for reference. If you need to buy cylindrical roller bearings or replace an old bearing, or cannot find the model you need in the chart, please contact BKZ Industry with your bearing number, size, drawing, or application requirements. As an ISO 9001 certified bearing manufacturer with 2 factories, BKZ Industry can help you confirm the suitable cylindrical roller bearing and offer reliable bulk supply.
