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.
