Frequently Asked Questions about This Product
1. How to choose the tolerance ranges for the shafts and mounting holes that match this product?
For the mounting holes: H7.
For the shafts: d8, e7, g6. The selection should be made according to the actual operating conditions.
2. What are the differences between the standard model and the thin-wall model?
The wall thicknesses of the standard model and the thin-wall model are different. The standard model is better able to withstand larger loads, while the thin-wall model cannot bear relatively large loads.
3. How does the product achieve lubrication-free performance?
The graphite on the product will form a thin graphite film on the shaft. Meanwhile, the last process of the product is oil immersion, and there will be a certain amount of lubricating oil stored in the graphite holes, ensuring that the product has certain lubrication-free characteristics.
4. Why is there inconsistency in the color and appearance of the product?
For copper alloy products, oxidation will occur when they are placed for a long time, and the color will become darker. New products have a lighter color. This is a normal phenomenon.
