Spindle nuts for heavy machinery, in wear zinc alloy

We manufacture  spindle nuts in zinc cast alloys ASTM ZA27 and ZA303 for various heavy  machinery.Special casting technologies are adopted for high quality and sound products. Advantages: 1) High strength and high toughness 2) Low friction coefficient and high heat conductivity 3) The service life is one to two time higher than tranditonal copper alloyed nuts. 4) Low specific gravity than copper alloys and easy to handling, movement and Installation. 5) Low price. Approx.20% cost less than copper alloys. 6) Perfect casting properties, sound castings and easy machining. 7) Good properties of self lubrication and absorbing vibriation. Applications:substitute for copper alloy parts with working conditionds of low temperature, mediun and low velocity movement, heavy load and fluctuating impact vibriation like spindle nuts,bushings,bearing shells,worm wheels , sliding rail, sliding plates etc. SAM manufactures the parts to customers’drawings and specifications. Consultation for Zinc cast alloy ZA303 or ZA27 spindle nuts is available on request . Enquiries and orders are welcome.
