FAQ
Q: Are GEK series bearings suitable for high-speed applications?
A: They are mainly designed for oscillating and low-to-medium speed movement, rather than high-speed continuous rotation.
Q: How do you prevent corrosion in harsh environments?
A: Material selection such as stainless steel options and proper surface treatment help improve corrosion resistance in harsh conditions.
Q: Can these bearings handle misalignment during operation?
A: Yes, spherical structure allows angular misalignment while maintaining smooth movement and load distribution.
Q: What type of maintenance is required during use?
A: With PTFE liner design, the bearing requires minimal maintenance under normal working conditions.
Q: Can you provide customized tolerance or fit class?
A: Yes, we can adjust tolerance and fit class based on specific engineering requirements.
