Frequently Asked Questions
Q: Are these genuine SKF equivalents?
Yes — fully compliant with SKF dimensional, material, and performance standards (not counterfeit; factory-direct OEM-grade).
Q: Can they handle shock loads?
Designed for steady axial loads; for intermittent shock, we recommend P5/P4 grade with Z3V3 vibration class.
Q: What’s the max RPM at 120mm bore?
Up to 3,200 rpm (grease-lubricated, P0, ambient 20°C) — consult our engineer for custom speed/life calculation.
Q: Do you support custom packaging or labeling?
Yes — OEM/ODM service includes branded cartons, pallet labeling, and bilingual documentation.
