Self lubricating fiber composite material wrapped bearing
GXT-60 linear pulley bearing
Features: low friction coefficient, high load-bearing capacity, resistance to different axial degrees, wear resistance, low water absorption, corrosion resistance, impact resistance
structure
Wear resistant layer: PTFE and high-strength fiber pre woven fabric, unique weaving design, the inner surface of the product presents a concave convex structure, reducing the contact area between the product and the pin shaft. The friction coefficient is the lowest among the tension series products. It is suitable for testing and practical application in situations where low friction coefficient is required, such as linear motion and pulley components, without jerking and anti abnormal noise.
Substrate: Glass fiber and epoxy resin cured body, giving it the same compressive performance as GMM and others.
Application: Recommended use of straight lines and guide wheels
