NTN cylindrical roller bearings with the 4R designation are built for high radial loads and high speeds. The cylindrical rollers run on parallel raceways, which spreads the load evenly. These bearings are common in industrial drives, gearboxes, and mining equipment. MR Industrial Accessories LLC supplies them to customers across the United States and in several Latin American countries.
The part number tells you what you are looking at. References like 4R2035, 4R2437, and 4R2906 all belong to the 4R series, which identifies cylindrical roller bearings. The digits after the letters point to dimension and internal design variants. To pick the right code, you need the housing and shaft dimensions, plus the load and speed conditions of the application.
You will find these bearings in gearboxes and reducers, as well as in equipment for the food, cement, steel, and mining industries. They also show up in pumping equipment, industrial fans, and conveyors. Their ability to take heavy radial loads and their rigidity suit demanding environments where reliability matters.
When selecting, consider the sealing type (open or sealed), the internal clearance, and the lubrication method. Shaft-to-housing alignment must be precise to avoid extra stresses. During mounting, apply the proper fitting load and use tools that will not damage the rollers or raceways. Use the lubrication recommended by the manufacturer to support a long service life.
For equivalents, NTN cylindrical roller bearings can replace those from other brands with similar designations, provided the main dimensions and tolerances match. Always verify the complete code and technical specifications before substituting a reference. If you are unsure, our team can help you find the compatible part for your equipment.

Frequently asked questions
- What does the 4R designation mean in NTN bearings?
- The 4R series identifies single-row cylindrical roller bearings. The numbers that follow indicate variants of dimensions and internal design. To interpret a specific code correctly, consult the technical catalogue or get advice from a specialist.
- How do I choose the right cylindrical roller bearing for my application?
- Consider the radial load, rotation speed, available space, and environmental conditions. Also define the sealing type, internal clearance, and lubrication method. With this data, we can recommend the exact code you need.
- Are NTN bearings interchangeable with other brands?
- In many cases, they are interchangeable with bearings from other brands that share the same dimensions and tolerances. However, it is essential to verify the complete code and technical specifications to ensure correct operation. We can help you with that verification.
