Product Introduction
The 93787/93127CD is a highly specialized double-row tapered roller bearing engineered for continuous operation in severe-duty environments. Featuring dimensions of 200.03 x 317.5 x 127 mm, the "CD" suffix signifies a double outer cup equipped with lubrication holes and an oil groove. This crucial design enhancement ensures that lubricant is efficiently directed directly into the bearing's rolling contact zones, dramatically reducing heat and wear during heavy operation. Built from premium high-carbon chromium steel, the 93787/93127CD is the ultimate solution for heavy industrial gearboxes and heavy equipment wheel hubs.
Applications
Heavy industrial gear reducers and wind turbine drivetrains.
Mining excavation equipment and large haul trucks.
Heavy-duty construction machinery wheel ends.
FAQ
Q: What is the difference between a "D" and a "CD" cup?
A: While both represent a double cup, the "CD" specifically indicates that the double outer ring features an oil groove and lubrication holes for centralized lubrication systems.
Q: Can this bearing be used in sealed environments?
A: This bearing relies on external oil bath or centralized grease systems, making it ideal for large gearboxes rather than pre-sealed standalone applications.
