Frequently Asked Questions

Q: Why is zinc galvanization important for greenhouse bearings?

Greenhouses are high-humidity environments often exposed to fertilizers. Zinc galvanization provides a critical protective layer that prevents oxidation and rust, significantly extending the life of the bearing.

Q: How often should I lubricate these pillow block bearings?

Depending on the usage intensity, we recommend re-lubricating through the built-in port every 6 to 12 months to ensure smooth operation and minimize wear.

Q: Can you provide custom sizes for specialized greenhouse pipe diameters?

Yes, while we offer standard 32mm, 48mm, and 60mm sizes, we specialize in OEM customization and can manufacture bearings to meet your specific design requirements.

Q: Which greenhouse systems are most suitable for these bearings?

They are ideal for roof ventilation shafts, roll-up curtain side systems, motorized drive units, and general structural supports like irrigation arms.

Q: What signs indicate that the bearing needs to be replaced?

Abnormal noise during rotation, visible misalignment of the shaft, or excessive vibration are primary indicators that the bearing unit should be replaced.

Q: Do you support international shipping and customs documentation?

Absolutely. We provide full export support, including Certificates of Origin (CO), Form A, and all necessary shipping documentation for global delivery.
