• Limit speed:
  • With Grease Lubrication : Up to 3,000 rpm
  • With Oil Lubrication : Up to 4,000 rpm
• Hermetic Seals : Rubber seals (RDU type) on both sides for effective protection against dust and humidity.

How It's Made and Materials

MRC 1922RDU bearing consists of:

• Inner and Outer Ring : Made of hardened chrome steel, offering wear resistance and long operating life.
• Balls : Made of high precision chrome steel, they ensure smooth rolling and reduce friction.
• Cage : It can be made of steel or brass, it keeps the balls equidistant and prevents contact between them.
• Seals : Rubber seals on both sides protect the bearing from contaminants and keep the lubricant inside.

Mathematical Formulas for Characteristics

• Nominal Bearing Life (L10h):

  $$L$$

  Where:

  • L10hL_{10h} $L$ 10 h ​=
  • CC $C$ = Dynamic load capacity (kN)
  • PP $P$ = Equivalent bearing load (kN)
  • pp $p$ = Life exponent (3 for ball bearings)
  • nn $n$ = Rotation speed (rpm)

• Calculation of Equivalent Load (P) for radial and axial loads:

  $$P$$

  Where:

  • FrF_r $F$ r ​=
  • FaF_a $F$ a ​=
