FAQ

Are your spherical bearings suitable for racing suspension systems?

Yes, our GE…COM series spherical bearings are widely used in racing suspension assemblies, lower control arms, linkages, and stabilizer bar connections.
Featuring an ultra-low friction coefficient (≤0.05) and high responsiveness, our bearings are ideal for high-speed dynamic motion systems, ensuring precise handling.

Have you supplied products for racing brands or events?

Yes, we have been providing OEM support to various racing suspension brands across Europe and the US, including motorsport tuners, rally car builders, and kart manufacturers.

How can I estimate or calculate the service life of your bearings?

The service life of a bearing (in oscillation cycles) depends on factors such as load, oscillation angle, frequency, and temperature. Although precise prediction is complex, standard industry formulas can provide useful estimates.
A simplified model is:G = b₁·b₂·b₃·(C/P)^k · 10⁶ cycles,where G is the life in cycles, C is the dynamic load rating, P is the equivalent dynamic load, b terms are correction factors (temperature, lubrication, etc.), and k is a material exponent.

How do you ensure consistent and stable quality across production batches?

We ensure product consistency through strict process control, including: 1. Raw material batch traceability, with certificates of compliance for all steel and PTFE inputs;
2. SPC (Statistical Process Control) during production, with real-time monitoring of key parameters such as grinding dimensions to ensure Cpk standards are met;
3. Standardized inspection procedures—inspectors are uniformly trained and use calibrated precision equipment (e.g., CMMs, profilometers);
4. A quality system aligned with IATF 16949 principles, emphasizing prevention over detection to eliminate quality issues at the source.

How do you ensure product quality?

We have strict quality control processes in place, from raw material sourcing, production, to final product inspection. All products undergo 100% quality inspection before leaving the factory to ensure defect-free products.

Do your bearings produce abnormal noise under high-speed compression and rebound?

No. Our PTFE self-lubricating liner eliminates metal-on-metal contact, preventing dry friction issues.
This ensures smooth and silent operation during high-speed compression-rebound cycles.Internal tests show no abnormal noise over 1 million compression-rebound cycles.
