Product Introduction
The 07100SA-07210X utilizes a modified inner cone (07100SA) paired with the 07210X cup to deliver boundary dimensions of 25.4 x 50.8 x 15.011 mm. The "SA" modified cone geometry is engineered to optimize internal stress distribution and improve lubricant oil flow across the roller-rib contact zone. Produced in automated CNC grinding facilities using vacuum-degassed chrome steel, this precision bearing minimizes frictional power loss, making it ideal for specialized power transmission applications.
Applications
High-performance automotive pinions and gearboxes.
Continuous-duty industrial power transmissions.
Precision agricultural equipment drives.
FAQ
Q: What does the "SA" suffix indicate?
A: The "SA" suffix denotes a specialized modification to the inner cone's internal geometry or corner chamfer for enhanced performance.
Q: Is this bearing interchangeable with standard 07100/07210?
A: Yes, boundary dimensions are identical, making it a direct upgrade in high-stress applications.
