Mechanical and Functional Characteristics

The SKF NN 3016 KTN/SPW33 bearing is designed to offer excellent performance in terms of:

Radial Load Capacity : Very high, suitable for applications requiring robust and long-lasting support.
Rigidity and Rotation Accuracy : High, thanks to the double row cylindrical roller design and SP tolerance.
Noise and Vibrations : Reduced to a minimum, contributing to silent operation without excessive vibrations.
Axial Displacement Compensation : Ability to handle axial displacements in both directions.
Provision for Relubrication : Equipped with annular groove and lubrication holes to facilitate maintenance and bearing life.

Materials and Construction

Bearing Material : Bearing steel, known for its hardness and durability.
Cage : Non-metallic, to reduce weight and improve efficiency.
Design : Inner ring with three flanges and outer ring without flanges to allow axial movement.

Mathematical formulas

To evaluate bearing performance, you can use the following formulas:

Bearing Life (L10):
$Factor)L_{10} = \left(\frac{C_{r}}{F_{r}}\right)^3 \times \frac{1}{ (1 - \text{Safety Factor})}$
Where:
- $C_{r}$ $C$ $_{r}$ is
- $F_{r}$ $F$ $_{r}$ is
Operating Speed:
$Admissible Speed n = d 60 \times Admissible Speedˋ$
Where:
- The permissible speed depends on the type of lubrication (7,000 r/min for grease, 8,000 r/min for oil-air).
- $d$ is the diameter of the hole.

Sectors of Use

The SKF NN 3016 KTN/SPW33 bearing is used in applications requiring:

High Precision : High precision machines and measuring instruments.
High Rigidity : Industrial applications at high speed and high load.
Noise and Vibration Reduction : Areas where noise and vibration need to be kept to a minimum.

Advantages of Purchase and Recommendations

Prompt Delivery : Buying ready for delivery ensures immediate availability and reduction of downtime.
Stock : Purchasing from stock can offer discounts and ensure continuous supply, which is essential for uninterrupted industrial operations.
