1. ما هو المحمل المطلي بالمطاط؟

يشير المحمل المطلي بالمطاط إلى محمل غير قياسي مناسب للاستخدام في ظل ظروف معينة، ويتم تشكيله عن طريق حقن أو ربط المنتجات المطاطية على سطح المحمل من خلال قالب الصب.

2. خصائص وتصنيف المحامل المغلفة بالمطاط

Rubber-coated bearings have excellent strength and wear resistance, heat resistance, hydrolysis resistance, and aging resistance. They have bright appearance, fine and smooth colloid surface, strong bonding between the colloid material and the shaft core, and a wide range of hardness.

In addition, rubber-coated bearings have the advantages of shock load resistance and low noise compared to ordinary bearings. Commonly used coating materials include the following:

(1) Polyurethane rubber rollers have good chemical properties, good solvent resistance, anti-aging, tear resistance, and good resilience.

(2) Silicone rubber coated bearings have good heat resistance, cold resistance, ozone and atmospheric aging resistance. The lack of electricity results in poor mechanical properties such as tensile strength and tear strength, and poor oil resistance and organic solvent resistance.

(3) Polyacetal (POM) coated bearings have high mechanical strength and rigidity, high fatigue strength, good resistance to organic solvents, and stronger wear resistance than polyurethane. However, they have the disadvantages of poor acid resistance, large molding shrinkage, and long life.

Easily decomposes under high temperature.

In addition, there are also rubber-coated bearings made of nitrile rubber, fluororubber and other coating materials.
