Boots For Translating Ball Screw Jacks

Joyce boots protect the lifting screw from dust, dirt, and help maintain lubrication. Standard boots, fabricated from neoprene-coated nylon also guard against moisture and corrosive contaminants. Adding protective boots may increase the closed height of jacks. For specific dimensional information based on jack design, refer to the information below.

  • Zippered boots
  • Horizontally mounted boots
  • Boots for extreme temperatures (-100°F to 500°F)
  • Boots for corrosive atmospheres
