SKF 32944

General Description

The SKF 32944 single row tapered roller bearing is designed to support combined radial and axial loads. Thanks to the geometry of the bearing, it is able to reduce friction levels during operation, improving operational efficiency. This bearing can be dismantled, allowing for easier assembly and maintenance, with interchangeable components. When mounted with preload, it ensures a rigid and stable arrangement.

Materials

• Inner and Outer Rings: High tensile bearing steel (SAE 52100), heat treated for hardness and wear resistance.
• Rollers: Hardened and ground steel, with smooth surfaces to reduce friction.
• Cage: Made of pressed sheet steel, designed to reduce weight and improve lubricant distribution.

Dimensions and Measurements

• Hole diameter (d): 220 mm
• External Diameter (D): 300 mm
• Total Width (B): 51 mm
• Inner Ring Width: 51 mm
• Outer Ring Width: 39 mm
• Contact Angle: 15.833°

Mechanical Characteristics

• Dynamic Load Coefficient (C): 601 kN
• Static Load Coefficient (C0): 1,000 kN
• Reference Speed: 1,500 r/min
• Limit speed: 1,900 r/min

Bearing Properties

• Number of Crowns: 1
• Hole Type: Cylindrical
• Cage: Sheet steel
• Sealing System: None (requires external lubrication)
• Lubricant: None pre-applied, can be relubricated externally.

Performance and Calculation Formulas

• Base Durability (L10): The duration can be calculated using the formula $L$, Where:
  • CC $C$ : Dynamic load rating
  • PP $P$ : Applied load
  • pp $p$ : Life exponent (generally 3 for roller bearings)
• Calculating Resonant Frequencies: Resonant frequencies can be calculated to prevent structural damage during high-speed operation.

Sectors of Use

• Automotive Industry: Used in differentials, transmissions and commercial vehicle components.
• Mining Industry: Applied in mining and crushing machinery.
• Machine Tools: Essential for spindles and supports.
• Wind Energy: Used in wind turbine drives.
• Metallurgical Industry: Suitable for rolling mills and other heavy applications.

Advantages of Purchasing in Stock

1. Immediate Availability: Purchasing from stock allows you to have the bearings immediately available, reducing machine downtime.
2. Reduced Costs: Stock bearings are often offered at reduced prices compared to purchasing to order.
3. Savings on Delivery Times: The long waiting times typical of customized productions are eliminated.
4. Ease of Maintenance: Having a spare bearing ready allows quick interventions and reduces maintenance costs.
