MRC 1922 RDU 0001 bearing

Model and Manufacturer :
The MRC 1922 RDU 0001 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 (high precision higher than class P5)
• Materials : Made of high quality hardened steel, with a hardened fiber cage (TB) for durability under high speed operating conditions.

Mechanical Features :
This bearing, designed for high precision and robustness, features a single angular contact ball configuration that allows for high axial and radial load capacity. The RDU model is designed for universal configurations requiring precise fit and balanced axial load. Standard lubrication ensures smooth movement, reducing friction and operating temperatures.

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

1. Equivalent dynamic load capacity : C=X⋅Fr+Y⋅FaC = X \cdot F_r + Y \cdot F_a $$C$$ $$=$$ $$X$$ $$\cdot$$ $$F$$ r ​+ $$Y$$ $$\cdot$$ $$F$$ a ​where FrF_r $F$ r ​is FaF_a $F$ 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 operate reliably.

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 required.

Advantages of stock purchasing :
Purchasing in stock allows you to avoid production wait times, ensuring immediate availability for urgent maintenance and ensuring that 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.
