Product Introduction
The 8F3170 is a robust industrial spherical roller bearing engineered to perform under extreme shock loads, high radial forces, and conditions of angular shaft misalignment. Measuring 65 mm inner bore, 120 mm outer diameter, and 46 mm width, this double-row bearing features a spherical outer raceway that allows automatic self-alignment without increasing friction or internal stress. Crafted from vacuum-degassed GCr15 high-carbon chrome steel, the 8F3170 provides excellent structural fatigue resistance, making it an ideal replacement component for heavy industrial machinery, vibratory equipment, and mining drive systems.
Applications
Vibrating screens, stone crushers, and mining pulverizers.
Industrial conveyor drive rollers and paper mill equipment.
Heavy agricultural machinery, industrial fans, and gear units.
FAQ
Q: What is the benefit of the spherical design in the 8F3170?
A: It automatically corrects shaft bending or housing misalignment up to 1.5°–2° without localized edge loading on the rollers.
Q: Can this model be supplied with C3 internal clearance?
A: Yes, we offer standard C0 as well as C3 and C4 increased radial internal clearances for elevated temperature operations.
