Product detailed description
The SKF NN 3016 KTN/SPW33 is a super-precision double-row cylindrical roller bearing engineered to provide a unique balance between load-carrying capacity, rigidity, and speed. This bearing is particularly suitable for applications requiring high radial load capacity and exceptional running accuracy.
Key Features:
- Design: Double-row cylindrical roller bearing with a tapered bore (1:12) and non-metallic cage.
- Flanges: Three flanges on the inner ring and no flanges on the outer ring, allowing accommodation of axial displacement in both directions.
- Lubrication: Equipped with an annular groove and lubrication holes for effective lubrication.
- Mounting: Separable design simplifies mounting and dismounting, especially when both rings require an interference fit.
