Frequently Asked Questions
- Q: What does "precision fit" mean for guide systems?
A: It means the bushing is machined to tight tolerances so it seats accurately in shock absorber guide systems, preventing misalignment and uneven wear.
- Q: What lubricants are used?
A: The bushing uses PTFE, POM and graphite as self-lubricants, with oil-based lubrication also supported.
- Q: Is it suitable for oilless applications?
A: Yes. It is designed as an oilless bearing and runs smoothly in oil-free and self-lubricating environments.
- Q: What certifications do you hold?
A: Production is certified to IATF16949:2016, ensuring automotive-grade quality management.
- Q: Can I order custom shapes and sizes?
A: Yes. Cylinder and thrust pad shapes are available, and we support custom dimensions to your drawings.
- Q: What is the delivery time?
A: Delivery is normally about 3-4 weeks, depending on quantity and customization.
