SKF QJ 219 N2MA PRICE 574 EUROS

The SKF QJ 219 N2MA bearing is an angular contact ball bearing, with a four-point contact design. This type of bearing is designed to support radial and axial loads, and is particularly suitable for applications requiring high precision and high performance. The QJ 219 N2MA is commonly used in industrial machinery, electric motors and in applications requiring high speeds.

Main technical specifications:

• Internal diameter (d): 95 mm
• External diameter (D): 170 mm
• Width (B): 32mm
• Weight: 3.3039 kg
• Bearing type: Angular contact ball with four contact points
• Lubrication: Can be lubricated with grease or oil, depending on operating specifications

Materials and construction:

The SKF QJ 219 N2MA bearing is made of high quality steel, designed for durability and wear resistance. The steel or polymer cage allows for smooth movement of the balls, minimizing friction. Its construction makes it ideal for applications where vibrations and radial or axial loads are present.

Sectors of use:

This bearing is particularly useful in areas such as:

• Automotive : for engines and transmissions.
• Industrial machinery : in machine tools, compressors, pumps, and electric motors.
• Aerospace and railway industry : where high tolerances and resistance to severe operating conditions are required.

How to assemble:

The QJ 219 N2MA must be mounted on shafts or housings that are perfectly clean and free of impurities. It is important to apply adequate lubricant and maintain optimal operating temperature to ensure correct operation and long life of the bearing.

Sizing formula:

Bearing sizing depends on the load and speed of the application. The basic formula for calculating the dynamic bearing load is:

$$C$$

where CC $C$ is the dynamic load, ff $f$ is a sizing factor specific to the bearing type and dd $d$ is the diameter. To obtain the optimal sizing, it is recommended to consult a specialized engineer to adapt the bearing to the specific needs of the application.

Price and purchase:

The average price of an SKF QJ 219 N2MA bearing is around €774​

. Purchasing stock bearings, like this one, is advantageous as it allows you to avoid long waiting times for production and reduce overall costs, also guaranteeing immediate availability in case of urgent needs.
