MRC 1922 RDU 0001 bearing

Model and Manufacturer :
MRC 1922 RDU 0001 bearing is a high-precision angular contact ball bearing manufactured by Marlin Rockwell Corporation (MRC). This company specializes in the production of precision bearings used in numerous industries, including industrial, aerospace and automotive. MRC products are known for their quality materials and wear resistance.

Main technical specifications:

• Internal diameter : 110 mm
• External diameter : 150 mm
• Width : 40 mm
• Contact angle: 15°
• Weight : 1.72 kg
• Accuracy : Class P4 (higher precision than class P5)
• Materials : Made with high-quality hardened steel, with a hard fiber (TB) cage for durability under high-speed operating conditions.

Mechanical Characteristics :
This bearing, designed to offer high precision and robustness, features a single oblique ball configuration which allows for high axial and radial load capacity. The RDU model is intended for universal configurations where precise coupling and balanced axial load are required. Standard lubrication ensures fluidity in movements, reducing friction and operating temperature.

Main mathematical formulas : To evaluate performance, formulas are used that concern the calculation of the dynamic and static load, such as:

1. $$Equivalent$$ $$dynamic$$ load capacity : $$C$$ $$=$$ X⋅Fr $$+$$ $$Y\cdot FaC$$ =​​​​​​​​​​ a ​is XX $X$ , YY $Y$ are the specific bearing coefficients.
2. Limiting speed : depends on the precision of the bearing and its size, representing the maximum speed at which it can reliably operate.

Areas of use :
It is mainly used in high-precision industrial machinery, such as spindle systems, turbines, robotics and medical equipment, where reliability and consistent performance are needed.

Advantages of purchasing from stock :
Purchasing from stock allows you to avoid production waiting times, ensuring immediate availability for urgent maintenance and ensuring that the technical specifications are verified in advance.

Assembly : For optimal assembly, it is recommended to use specific tools to avoid damage to the contact surfaces and ensure correct alignment, especially in configurations with high axial loads.
