UNIVERSAL Worm Gear Motors

BLOCK Worm Gear Units are characterised by their robust design. The UNICASE principle, which has been tried and tested since the 1980s provides high functionality, low maintenance and a long service life.

SK 02040.1 Helical Worm Gear Units
NEW: We have thoroughly redesigned our two-stage SK 02040 Helical Worm Gear Units. The new SK 02040.1, made from high strength aluminium, replaces the previous product. The die-cast aluminium housing guarantees maximum strength and rigidity with low weight and can be further protected by additional measures such as the highly effective nsd tupH surface treatment. The SK 02040.1 has a wide power range from 0.12 to 1.1 kW and an output torque of up to 100 Nm. The wide range of speed ratios (from 5.37:1 up to 330:1) enables optimum adaptation to the customer’s requirements. The motor can be mounted directly without a coupling or via an adapter (IEC or NEMA).
