Technical Data Sheet: MRC 7118KRD5E 0001

Overview:

The MRC 7118KRD5E 0001 is an angle contact ball bearing designed for high-precision applications, such as machine tools and high-speed applications. This bearing, manufactured by MRC Bearings , is part of the SKF family, a world leader in bearing manufacturing.

Technical Specifications:

• Hole diameter : 90 mm
• External diameter : 160 mm
• Width : 30 mm
• Contact angle: 29°
• Bearing Material : Bearing Steel
• Cage Material : Brass
• Weight : Approx. 6.87 kg

Mechanical Features:

• Basic dynamic load : Typical values ​​for these bearings vary depending on the configuration, but are generally around 72-80 kN.
• Basic static load : Generally greater than 65 kN.
• Limit speed : Approximately 7,000 rpm.
• Reference speed : Up to 11,000 rpm.

These bearings are designed for applications requiring both high radial and axial loads. Their angled contact design efficiently handles axial loads on both sides, making them ideal for use in high-precision applications such as machine tools, motors, and turbines.

Materials and Construction:

• Bearing Steel : The bearing is made of high-quality steel, which is wear-resistant and can withstand high loads without deformation.
• Brass Cage : Brass cage material provides corrosion resistance and the ability to run at higher speeds without deterioration.

Areas of Use:

• Machine tools : Ideal for machining centers and precision lathes.
• Power Industry : Used in turbines and generators where high speed and precision are required.
• Automotive : Suitable for applications in high-speed engines and transmission systems.

Useful formulas:

To calculate bearing life:

• Duration L10 (in hours) = (C / P)³ × (16.666 × n) Where:
  • C = Basic dynamic load (kN)
  • P = Equivalent load (kN)
  • n = Rotation speed (RPM)

This formula helps estimate bearing life under normal operating conditions.
