Technical data sheet: MRC 7118KRD5E 0001

Overview:

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

Technical Specifications:

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

Mechanical Characteristics:

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

These bearings are designed for applications where both high radial and axial loads are required. Their contact angle design allows for the efficient handling of axial loads on both sides and makes them ideal for use in high-precision applications such as machine tools, engines 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 offers corrosion resistance and the ability to run at higher speeds without deteriorating.

Sectors of Use:

• Machine tools : Ideal for machining centers and precision lathes.
• Energy Industry : Used in turbines and generators where high speed and precision is 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 = Rotational speed (RPM)

This formula helps estimate bearing life under normal operating conditions.
