SKF Explorer QJ219 N2MA Bearing Detailed Technical Data Sheet

1. General Description: The SKF Explorer QJ219 N2MA bearing is a four-point contact ball bearing designed to accommodate axial loads in both directions and small radial loads. This bearing type is known for its high-speed capability and reduced axial clearance requirements compared to double-row angular contact bearings. It is particularly useful in applications requiring 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 optimum resistance to high speeds.
• Configuration: Open, without seals, with two locating grooves on the outer ring to prevent rotation of the ring itself.
• Inner Ring: It is radially split for ease of assembly.

3. Technical Specifications:

• Internal Diameter (d): 95 mm
• External Diameter (D): 170 mm
• Width (B): 32 mm
• Contact Angle: 35 degrees, optimized to support high axial loads.
• Weight: Approximately 3.3 kg
• Dynamic load capacity (C): 212 kN
• Static load capacity (C0): 232 kN
• Maximum 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 the 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 Features: The four-point contact configuration allows the bearing to accommodate axial loads in both directions, reducing wear and extending bearing life. The solid brass cage ensures even load distribution across 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 rating and PP $P$ is the equivalent load).
• Calculating the limit speed: Consider the specified limit speed parameters and ensure that the operating conditions fall within the recommended values.

7. Advantages of purchasing in stock: Purchasing the SKF Explorer QJ219 N2MA bearing in stock guarantees:

• Immediate availability: Reduce downtime for urgent replacements.
• Reliability: Guarantee that the product has not undergone alterations or deterioration due to prolonged storage in non-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 to:

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

Conclusion: The SKF Explorer QJ219 N2MA bearing is a versatile, high-performance solution, particularly suitable for industrial applications requiring high speeds, high load carrying capacity, and long life. Thanks to its robustness and reliability, it represents a sound investment for those requiring readily available components of guaranteed quality.
