Detailed technical data sheet of the SKF 63008-2RS1 bearing

General Description

The SKF bearing 63008-2RS1 is a single row deep groove ball bearing, designed to support radial and axial loads in both directions. Thanks to its simple, robust and versatile design, it is widely used in various industrial applications, especially where high speed and low maintenance are required. The presence of integrated seals on both sides (2RS1) increases its life, maintaining the internal lubricant and protecting from contaminants.

Technical Specifications

• Hole diameter (d): 40 mm
• External diameter (D): 68 mm
• Width (B): 21mm
• Dynamic load (C): 16.8 kN
• Basic static load (C₀): 11 kN
• Limit speed: 6,300 rpm
• Net weight: 0.27kg

Mechanical Characteristics

• Material: Bearing steel
• Sealing system: Double-sided contact seals (2RS1), which retain the lubricant and protect against external particles.
• Lubrication: Grease, periodic relubrication is not necessary.
• Internal radial clearance: CN (standard clearance for general applications).

Useful formulas

To calculate bearing life and performance, the following formulas can be used:

• Nominal life (L₁₀):
  L10=(CP)3L₁₀ = \left( \frac{C}{P} \right)^3
  $L$ 10 ​= $($ P C ​) 3 Where C is the dynamic load capacity and P the applied load.

• Limit speed: The maximum safe speed for continuous use is 6,300 rpm.

Materials

• Inner/outer ring: High quality tempered steel, treated to resist wear and corrosion, ensuring long life even under conditions of intensive use.
• Balls: Made of steel with a high chromium content, to withstand high mechanical stress and maintain low rolling resistance.

Typical Applications

• Industrial machinery
• Electric motors
• Pumps
• Compressors
• Automotive applications
