It is suitable for use to precision machinery and auxiliary machinery to maintain precise revolution and equal deviation. It is precision and technology intensive gear.
It minimizes back-lash by creating deviation between tooth thickness of starting point andfinishing point by applying differently to A lead and B lead when it touches the tooth pitch atworm shaft. When the back-lash is increased by friction abrasion it can be corrected by wormshaft adjusted within the specified value. Repair and maintenance of its precision is lessexpensive and simplified.

• Center Distance is maintained same all the way

• Easy adjustment of back-lash

• Long Service life

• Easy control of precision
