Manufacturing Program of the HYDRAULICS Division
1. Parts for Hydraulic Motors
We supply namely flanges, shafts, brake shafts, pinion shafts and similar parts to manufacturers of hydraulic motors.
2. Hydraulic Rolls and Their Components
We make single-acting or double-acting hydraulic rolls, telescopic rolls, plungers and individual props, ranging from the simplest design to special hydraulic rolls with a maximum diameter of 400 mm, maximum length of 3 m. We also supply hydraulic sets and elements, and design and construct hydraulic rolls according to customers’ specifications. We are able to cooperate and structurally design problematic hydraulic nodes even in fairly large assemblies.
3. Shafts
We make shafts ranging from 120 upto 240 mm in diameter and from 1000 upto 2500 mm in length that are designed for electric motors and electric generators. The shafts have a straight splineway or a splineway with spiral diameter and quick flute. Some shafts with the straight splineway are obliquely drilled through for wiring. Shafts are made of common grade steels or stainless steels. We are also able to make shafts of other sizes.
4. Manufacture of Other Parts
Manufacture of gear wheels with external straight and oblique toothing (max. module 10 mm), manufacture of sprocket wheels, manufacture of parts with involute splining, manufacture of gear wheels with internal toothing (max. module 8 mm), manufacture of eloidal bevel gear wheels (max. module 11 mm/tooth depth 23 mm, outside diameter of wheel max. 540 mm), components for hydraulic presses, gear boxes, etc.
