Features Of Phenolic Cloth Clamp Sleeve

  • 1

    Can save a lot of non-ferrous metals, such as copper, aluminum, tin, lead, etc.

  • 2

    Have good mechanical properties, enough compressive strength, and fatigue strength, and elastic modulus is small.

  • 3

    Can absorb vibration, does not break the roller, bearing shell surface pressure is uniform, and does not deform.

  • 4

    The friction coefficient is small, and the power loss is reduced by 15 - 20 % compared with the metal.

  • 5

    No matter under what circumstances, will not lose the shaft head. And when in use, the shaft head is polished to improve lubrication conditions.

  • 6

    The lubricant is convenient to use, tap water and emulsion can be used, and the cost is reduced. 

  • 7

    The utilization rate is improved, the machining program is saved, and the cost is reduced.
