The phenolic resin bearing bush is an advanced material designed to withstand high wear and harsh environments. It offers excellent thermal resistance, chemical stability, electrical insulation, and low friction properties. Its unique composition ensures durability, reduces maintenance, and improves the efficiency of machinery in various industrial applications. This product is especially popular in steel rolling mills, paper manufacturing, and shipbuilding industries due to its reliability and long service life. **Key Features:** 1. **Material Efficiency:** Saves a significant amount of non-ferrous metals like copper, aluminum, tin, and lead. 2. **Superior Mechanical Properties:** Provides sufficient compressive strength, fatigue resistance, and a low elastic modulus, which helps absorb vibrations and prevent damage. 3. **Low Friction:** Reduces power loss by 15–20% compared to metal bearings, improving energy efficiency. 4. **No Shaft Head Loss:** Maintains the integrity of the shaft even under extreme conditions, with improved lubrication through polishing. 5. **Easy Lubrication:** Can be lubricated using tap water or emulsions, reducing costs and enhancing performance. 6. **Cost-Effective:** Replaces traditional materials like cotton cloth, reducing machining time and overall production costs. **Applications:** This bearing bush is ideal for major, medium, and small-scale iron and steel enterprises. It's commonly used in ball mill bearings, 550 bearings, and 250 bearings. Our factory can custom-make these parts based on client specifications and drawings. **Physical Properties:** - Specific Gravity: 1.35 - 1.50 - Water Absorption: ≤ 1.5% - Heat Resistance (Martin): ≥ 125°C - Brinell Hardness: ≥ 30 kg/mm² - Compressive Strength: ≥ 1800 kg/cm² Custom orders are welcome.
