Bellows Boot

Model: Bellows Boot for worm gear screw jack
Place of Origin: Made In China
Brand Name: JACTON
Bellows boots are available for all sizes and configurations of JACTON Worm Gear Screw Jacks. A boot protects the lifting screws from contamination and helps retain lubricant to ensure long jack life. Standard boots are sewn from black polyurethane-coated polyester fabric type for oil, water and weather resistance and are acceptable for use in -15°C to +80°C environments, includes extra 2 pieces galvanised hose clips too. 

Bellows boots fully retracted length=exact stroke / 0.83
Note: When inverted configurations jacks with boots, total lifting screws stroke=mounting frame thickness + boots fully retracted length + required stroke

Bellows boots for translating screw jacks: The bellows boots end cuff is designed to fit standard lifting screw end fittings, the top plate and the clevis end. 
Bellows boots for travel nut rotating screw jacks: Boots for upright rotating and inverted rotating jacks are ordered as separate line items. Typical rotating jack applications require two boots, one between the housing and the travel nut and one from the travel nut to the end of the lifting screws. Each boot for a rotating screw jack is ordered as a separate line item. Installation arrangements for rotating worm gear screw jacks vary, therefore boots for rotating jacks must be specified by the customer.

Guides are recommended for all horizontal applications where travel exceeds 600mm or if the bellows boots needs to remain centered around the lifting screw. The recommended number of guides is one guide for each 600mm of travel length. EXAMPLES: 300mm of travel=no guides, 600mm of travel=one guide, 1175mm of travel=one guide, 1200mm of travel=two guides etc. Standard boots are furnished with tie straps for jacks with greater than 1650mm travel. Tie straps are attached from convolution to convolution and help the boot extend uniformly.
