Pfaff-silberblau stainless steel SSP and SHE screw jacks
Pfaff-silberblau has released its stainless steel SSP and SHE screw jacks for extreme environment corrosive applications, including the papermaking process industry, food-grade production and offshore applications.
Lifting capacities for the SSP with integrally cast swivel brackets range from 15 to 25 T. All components that can come into contact with corrosive materials have been made from corrosion-resistant materials.
The jacks are designed for easy cleaning, from the shape of the stainless steel housing, through each component that comes into contact with harsh corrosives. The lift screw, bearing housing caps and clevis are also made in stainless steel; the worm wheel and guide rings are made from special bronze, with all fasteners in corrosion-resistant materials.
SSP jacks have the mounting face built into the casting with externally threaded mounting screws. There are no bearing covers, and the design dispenses with tapered roller input bearings and replaces these with angular contact ball bearings.
SSP stainless jacks are self locking, with their whirled screw shafts available in any length required. The clevis or head can be standard or made to customer requirements, again in stainless steel. Two ratios are available (N and L), and the jack can be configured as a travelling screw or a travelling special nut to customer dimensions.
For applications not requiring a pivoting mount, the company offers the traditional SHE series in full stainless steel construction. Three different housings give a range of 3 to 15 T, with the N and L ratios complementing the range.
The jacks are delivered standard with mineral-grease-based lubricants, but can also be delivered with food-grade grease or other lubricants without need for any modifications.
