SKF N10 series super precision single row cylindrical roller bearings come standard with 1:12 tapered bore (model suffix K).

The tapered bore is the best choice for because the taper allows precise adjustment of clearance or preload during mounting.

The bearings have two integral flanges on the inner ring and no flanges on the outer ring.

To improve lubricant flow, these bearings can be equipped with lubrication on the outer ring upon request.

1, Basic bearing design
The basic design single row cylindrical roller bearing is equipped with roller centering without glass fiber reinforced PA66

cage as standard, with bore diameter up to 80mm (model suffix TN), larger sizes are equipped with glass fiber reinforced

cages (model suffix TN9). These bearings are particularly suitable for high precision applications.

2, High-speed bearing design
PEEK asymmetric cage (model suffix TNHA) or carbon fiber reinforced PEEK asymmetric cage (model number suffix PHA).

Both types of cages are outer ring centering cages, optimizing lubricant effectiveness and avoiding lubricant shortage for

high speed motion. The PHA cage is a centring cage for the outer ring, optimizing lubricant effectiveness and avoiding

inadequate lubrication for high speed motion. When comparing the two types of cages, the asymmetric PHA cage provides

more guidance and lubrication for greater performance.

Compared to bearings with PEEK cages, bearings with carbon fiber reinforced PEEK cages can accommodate up to 30%

higher speeds in grease lubrication applications and 15% higher speeds in oil and gas lubrication systems.
For applications requiring higher speeds beyond the stiffness range, such as the non-tooling end of a machine spindle,

bearings with a typical number of rollers are available upon request.
