PRODUCT DETAILS

Product Description

	Alumina Ceramic Guide Roller Alumina ceramics have good mechanical strength, high hardness and good wear resistance. Excellent insulation and chemical stability. Good high temperature resistance, excellent dielectric. It has high thermal conductivity and good conductivity.
Alumina guide Good insulation, free of static electricity, resistant magnetic. Superb thermal conductivity coefficient and thermal shock property.
	Advantages of Textile Ceramic 1. Exceptional wear resistance and hardness better than metal ones. 2. Low yarn tensions without any yarn damage. 3. Long service life on both special yarns and raw materials with aggressive additives.
Ceramic guide Highest yarn cleanliness without any fault silk occasion. Excellent mechanical strength, fracture toughness, and bending strength. Exceptional wear resistance and hardness better than metal ones.
