SKF 32944

General Description

The SKF 32944 single row tapered roller bearing is designed to accommodate combined radial and axial loads. The bearing's geometry reduces friction during operation, improving operating efficiency. This bearing is separable, allowing for easy mounting and maintenance, with interchangeable components. When mounted with preload, it provides a rigid and stable bearing arrangement.

Materials

• Inner and Outer Rings: High-strength 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 stamped 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
• Speed ​​Limit: 1,900 r/min

Bearing Properties

• Number of Crowns: 1
• Hole Type: Cylindrical
• Cage: Steel sheet
• Sealing System: None (requires external lubrication)
• Lubricant: None pre-applied, can be re-lubricated externally.

Performance and Calculation Formulas

• Base Duration (L10): The duration can be calculated using the formula $L$, Where:
  • CC $C$ : Dynamic load coefficient
  • PP $P$ : Applied load
  • pp $p$ : Life exponent (generally 3 for roller bearings)
• Calculate Resonance Frequencies: Resonance 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-duty applications.

Advantages of Stock Buying

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