NTN KRV90XH/3AS belongs to cam follower, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for KRV90XH/3AS and any equivalents.
The NTN KRV series is a stud-type cam follower built around a cylindrical roller bearing. The integrated stud lets the unit run directly against a cam profile, track or guide rail, so it handles motion transfer where radial capacity and rigidity matter. Typical installations include lifting equipment, conveying lines and positioning mechanisms.
Reading a KRV reference is straightforward once you know the pattern. Take KRV10XH/3AS: the 10 is the roller outside diameter in millimeters, the X marks a reinforced section, the H points to a steel cage, and /3AS covers the sealing and lubrication execution. The same logic applies to KRV47XH/3AS, where 47 is the outside diameter. With that structure you can pick out the key dimensions and features of a unit before opening a catalog.
These cam followers appear in a broad range of plants, from automotive assembly and machine tool building to material handling, presses and guidance systems. Because they take radial loads and moderate axial loads, they suit drive cams, conveyor support rollers and cam mechanisms in textile, packaging and food processing machinery.
Selection comes down to the outside diameter, width, seal style and internal clearance. The KRV line includes single and double lip seal options, with or without pre-lubrication. At mounting, check alignment between the cam follower and the raceway, and confirm the lubricant matches the load and running speed. Getting the installation right is what keeps the bearing running through its service life.
Cam followers in the KRV series can be swapped for equivalents from other makers when the main dimensions and load conditions line up. If you are working from another brand's number, send it over and we can point you to the matching NTN reference, so the replacement stays safe and efficient.

Frequently asked questions
- What does the /3AS suffix mean on a KRV cam follower?
- It identifies a particular sealing and lubrication execution. Codes in this position describe the seal type and the level of protection against contaminants, which matters in dusty or damp conditions. Send the exact part number and we will confirm the details.
- How do I pick the right KRV cam follower for my machine?
- Start with the outside diameter, width and radial load, then factor in the environment. The KRV series comes in several sealing and clearance variants. Share the dimensions and the type of application and we will suggest the NTN reference that fits.
- Can a cam follower from another brand be replaced with an NTN KRV unit?
- It can, provided the main dimensions and load capacities correspond. Give us the original brand's part number on WhatsApp and we will identify the equivalent NTN reference for you.
