Mechanical and Functional Characteristics

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

Radial Load Capacity : Very high, suitable for applications requiring robust and long-lasting support.
Rigidity and Rotation Precision : High, thanks to the double row cylindrical roller design and SP tolerance.
Noise and Vibration : Reduced to a minimum, contributing to quiet operation and free from excessive vibrations.
Axial Displacement Compensation : Ability to handle axial displacements in both directions.
Relubrication Provision : Equipped with annular groove and lubrication holes for easy 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 displacement.

Mathematical Formulas

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

Bearing Life (L10):
$Safety)L_{10} = \left(\frac{C_{r}}{F_{r}}\right)^3 \times \frac{1}{(1 - \text{Factor of Safety})}$
Where:
- $C_{r}$ $C$ $_{r}$ is
- $F_{r}$ $F$ $_{r}$ is
Operating Speed:
$\times \text{Allowable Velocity}}{d}$
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 Stiffness : High speed, high load industrial applications.
Noise and Vibration Reduction : Areas where noise and vibration need to be minimized.

Benefits of Purchasing and Recommendations

Ready for Delivery : Buying ready for delivery ensures immediate availability and reduced downtime.
Stock : Buying from stock can offer discounts and ensure continuous supply, essential for uninterrupted industrial operations.
