FAQ – Frequently Asked Questions
Q1: What is the difference between Shore A 60 and other hardness grades?
Shore A 60 offers a medium-soft feel, providing good flexibility and shock absorption. It is suitable for applications where moderate load support is needed. If you require higher load capacity, we can offer harder grades like Shore A 70 or 80; for softer cushioning, Shore A 50 is an option.
Q2: Can I use this bearing in outdoor or wet environments?
Yes, the rubber material is resistant to water and UV degradation (if specified). However, for prolonged exposure to direct sunlight or extreme weather, we recommend adding UV stabilizers. Please contact us for custom formulations.
Q3: What is the maximum load capacity of this bearing?
The load capacity depends on the application and supporting structure. Generally, this bearing handles radial loads up to moderate levels. For precise load data, please provide your operating conditions, and our engineering team will calculate the suitable design.
Q4: Is the bearing lubricated or maintenance-free?
This rubber bearing is self-lubricating to some extent due to the material properties, but for extended life, occasional lubrication may be recommended depending on the application. We can also supply pre-lubricated versions upon request.
Q5: Can I get a sample before placing a bulk order?
Absolutely! We offer samples for quality evaluation. Please contact our sales team with your shipping details, and we will arrange a sample at a nominal cost (refundable with first bulk order).
Q6: What is the typical lead time for bulk orders?
For standard sizes and quantities, lead time is 15–25 working days after order confirmation. Customized products may require 25–35 working days. We will confirm the exact schedule upon order placement.
Q7: Do you provide technical drawings or installation instructions?
Yes, we provide dimensional drawings, installation guides, and technical datasheets for all our standard products. Custom drawings are also available upon request.
Q8: How do I ensure the bearing fits my shaft housing?
The 20mm ID fits a shaft of 20mm diameter, and the 40mm OD fits a housing bore of 40mm. For tight tolerances, we recommend a light press fit. If you have non-standard dimensions, we can produce custom sizes with a short lead time.
