High quality and suitable for many applications, INKOMA screw jack systems are perfect for lifting, lowering, and push or pull movements.
INKOMA HSG series cubic worm screw jacks are high quality engineering products for precise lifting, lowering and pivoting of loads, and are maintenance free under normal operation. The use of high quality grey cast iron and aluminium in the production of the housings guarantees a long life and a high operating margin. All housings have a cubic form and are machined on all faces.
Motor and screw jack assemblies can be installed in any position. The worm gearing has a specially modified form which results in low inter-gear specific pressures and an extended working life. The worm is manufactured from high quality alloy steel, hardened and ground.
Normally the spindle pitch and gear ratio are matched. Single start precision rolled screws are normally self locking. However safety regulations must be observed.
Various ball screw options may be selected. These permit higher lifting speeds than trapezoidal units. Screw jacks fitted with ball screws are not self locking. All installations should be fitted with brake motors.
