Detailed Technical Data Sheet of the SKF Explorer QJ219 N2MA Bearing

1. General Description: The SKF Explorer QJ219 N2MA bearing is a four-point contact ball bearing, designed to support axial loads in both directions and small radial loads. This type of bearing is known for its ability to operate at high speeds and reduced need for axial clearance compared to double row angular contact bearings. It is particularly useful in applications that require the support of high axial forces.

2. Components and Materials:

• Bearing Material: High quality bearing steel.
• Cage: Solid brass cage, designed for long life and optimal resistance at high speeds.
• Configuration: Open, without seals, with two positioning grooves on the outer ring to prevent ring rotation.
• Inner Ring: It is radially split to facilitate assembly.

3. Technical Specifications:

• Internal Diameter (d): 95 mm
• External Diameter (D): 170 mm
• Width (B): 32mm
• Contact Angle: 35 degrees, optimized to support high axial loads.
• Weight: Approximately 3.3kg
• Dynamic load capacity (C): 212 kN
• Static load capacity (C0): 232 kN
• Limit speed: 6700 rpm

4. Applications and Sectors of Use: The SKF QJ219 N2MA bearing finds application in various industrial sectors, including:

• Mechanical industry: Used in machinery requiring high precision and ability to support heavy loads.
• Automotive: Ideal for transmissions and systems requiring components with high load capacity and speed.
• Machine tools: Used in machines that operate at high speeds and require low maintenance due to extended bearing life.

5. Mechanical Characteristics: The four-point contact configuration allows the bearing to withstand axial loads in both directions, reducing wear and prolonging the useful life of the bearing. The solid brass cage ensures even load distribution on the balls, reducing the risk of overheating.

6. Formulas and Calculations for Optimal Use:

• Bearing life calculation: L10=(CP)3×106L_{10} = \left(\frac{C}{P}\right)^3 \times 10^6 $L$ 10 ​= $($ P C ​) 3 $\times$ $1$ $0$ 6 (where L10L_{10} $L$ 10 ​is CC $C$ is the dynamic load capacity and PP $P$ is the equivalent load).
• Calculation of the limiting speed: Consider the specified limiting speed parameters and ensure that the operating conditions are within the recommended values.

7. Advantages of Purchasing Prompt Delivery: Purchasing the SKF Explorer QJ219 N2MA bearing ready for delivery guarantees:

• Immediate availability: Reduce downtime in case of urgent replacements.
• Reliability: Guarantee that the product has not undergone alterations or deterioration due to prolonged storage in less than optimal conditions.
• Security of supply: Immediate control of product quality, verifying that it complies with the required technical specifications.

8. Maintenance: To ensure maximum bearing life, it is advisable:

• Regular lubrication: Use high-quality lubricants recommended by SKF.
• Vibration and temperature monitoring: Prevent premature damage by early detection of any operational anomalies.
• Checking the mounting conditions: Make sure that the bearing is mounted correctly to avoid excessive stress which could compromise its functionality.

Conclusion: The SKF Explorer QJ219 N2MA bearing is a versatile, high-performance solution, particularly suitable for industrial applications where high speeds, high load capacities and long life are required. Thanks to its robustness and reliability, it represents a safe investment for those who need readily available and guaranteed quality components.
