SKF QJ 306 MA bearing

General Description The SKF QJ 306 MA bearing is a radial angular roller bearing, designed for applications requiring robust and long-lasting support. It is ideal for radial and axial loads, thanks to its four contact point configuration, which offers greater flexibility in terms of application.

Materials and Construction

• Coating : Chrome steel, chosen for its resistance and hardness.
• Balls : Steel balls to reduce friction.
• Cage : Steel cage, designed to keep the balls in place and ensure smooth movement.

Dimensions and Weight

• Dimensions:
  • Internal diameter: 30mm
  • External diameter: 72mm
  • Width: 19mm
• Weight : Approximately 0.200 kg.

Mechanical Characteristics

• Maximum static load (C0) : 16.5 kN.
• Maximum dynamic load (C) : 10.5 kN.
• Limit speed : 9,500 rpm (with appropriate lubrication).
• Operating temperature : -30 °C to +120 °C.

Sectors of Use The QJ 306 MA bearing is widely used in various sectors:

• Mechanical industry : Metalworking machinery.
• Automotive sector : Transmissions and engines.
• Electrical sector : Electric motors and generators.

Mathematical Formulas To evaluate the bearing life, the following formula is used: L10=(CF)3L_{10} = \left( \frac{C}{F} \right)^{3} $L$ 10 ​= $($ F C ) 3 where:

• L10L_{10} $L$ 10 ​=
• CC $C$ = maximum dynamic load,
• FF $F$ = applied load.

Mounting Mounting of the SKF QJ 306 MA bearing requires:

1. Preparation : Thoroughly clean the tree and support.
2. Lubrication : Apply a suitable grease or oil.
3. Installation : Use an assembly tool to ensure damage-free installation.

Advantages of Purchasing in Stock Buying SKF bearings in stock offers significant advantages:

• Immediate availability : Reduction of machine downtime.
• Economic savings : More competitive prices for purchases in quantity.
• Guaranteed quality : SKF is synonymous with reliability and high performance.

Average price
