IKO NART10UUR Roller Follower, 10 mm bore, 30 mm OD, Caged, Sealed, Crowned Outer Ring
Available
This page covers 14 IKO NART Series non-separable roller followers (track rollers) (NART5UUR to NART50UUR, 5 to 50 mm bore): needle rollers in a cage, sealed type construction and a crowned outer ring. Choose the size in the options above; each variant has its own dimensions and ratings in the Model Details.
The NART series is the metric non-separable roller follower: side plates are fixed on both sides of the inner ring, so the unit comes as one piece with its inner ring. A roller follower (track roller) is a bearing designed for outer ring rotation, with rollers inside a thick-walled outer ring. The outer ring runs directly on the mating cam guide surface, and roller followers are widely used in cam mechanisms and in linear motions of conveying equipment.
In the part number, V marks the full complement type (no V is with cage), UU the sealed type and R the crowned outer ring. Every model on this page is with cage, sealed type, with a crowned outer ring.
Where this product is used
- Cam mechanisms, with the outer ring running directly on the cam guide surface
- Linear motions of conveying equipment
- Follower and track roller positions on a shaft
Features
- Non-separable roller follower with inner ring: side plates are fixed on both sides of the inner ring
- Needle rollers in a cage: a small coefficient of friction and suited to high speed rotations
- Sealed type: synthetic rubber seals in the clearances between side plates and outer ring keep dust and dirt out
- Crowned outer ring (R): moderates the edge load caused by mounting errors
- Prepacked with grease
- Basic dynamic load rating C 3,650 to 48,600 N and static load rating C0 3,680 to 95,600 N (each size in the Model Details)
- Track capacity 1,040 to 10,800 N on a 40 HRC mating surface

C is the basic dynamic load rating and C0 the basic static load rating; a is the mating seating dimension.
Selecting the right option
Pick the outside diameter (D, in mm) in the options above: the bore (shaft diameter), widths and ratings follow from the model number shown in the Model Details. Match the bore to the shaft you will fit.
This page is the crowned outer ring type (R in the part number). The crowned ring is effective in moderating the edge load caused by mounting errors.
Every model here has a cage, which gives a small coefficient of friction and suits high speed rotations.
Fitting and use
For the sealed type, match the side surface correctly to the mating seating surface given by dimension a in the Model Details and fix it. The mounting part should make even contact with the entire side plate surface: uneven contact may increase rotational torque and shorten the service life.
Keep the oil hole of the inner ring out of the loading zone, which can lead to a short bearing life.
Recommended shaft tolerance for the metric series is g6 or h6.
Lubrication: the models on this page are prepacked with grease.
Track capacity is the load that can be applied continuously on a steel cam guide surface of 40 HRC without deforming or indenting it. For a different hardness it is multiplied by the track capacity factor (0.45 at 30 HRC): ask AIMS if you need the factor for your guide surface.
If you are unsure which size suits your cam track and mounting, send AIMS the part number or the dimensions and we will help you confirm it.
