All-Plastic Sliding Bearing Standard Type/Precision Type

Frequently Asked Questions about This Product

1. The measured size of the product with calipers is larger and does not match the tolerance indicated on the drawing.
This type of product is formed by injection molding, and engineering plastic products have a certain linear expansion coefficient and are greatly affected by temperature and humidity. In the natural state, there is a certain amount of expansion and contraction allowance for the inner and outer diameters. It is necessary to measure the product after it is pressed into the H7 seat hole.

2. In what scenarios is it applied?
Engineering plastic products are suitable for customers who have requirements for noise. Some lubricants are added to the product, enabling it to be maintenance-free and have relatively strong anti-corrosion ability.

3. How to choose the tolerance ranges for the shafts and mounting holes that match this product?
For the installation holes: H7.
For the shafts: h9.
