Frequently Asked Questions
Q: Is this a genuine SKF product?
No—this is a high-precision aftermarket equivalent engineered to match SKF’s dimensional, material, and performance specs. Ideal for cost-conscious fleets and repair shops.
Q: What’s the expected service life under normal use?
80,000–120,000 km when installed correctly and maintained per OEM guidelines.
Q: Can I replace only one side?
Yes—but we recommend axle-set replacement for balanced wear and safety compliance.
Q: Do you provide test reports?
Yes—available upon request: hardness, vibration, load-life, and seal integrity reports.
