Steel is used when there is a need for a high strength design. But cast iron is mainly used because of its good wearing properties, excellent machineability and the ease that complicated shapes can be created due to the casting method. Castings are created by pouring molten metal into a mould and once the metal as cooled it takes the shape of the mould.<\/p>\n<p>The non metallic, materials used are generally wood, rawhide, compressed paper and synthetic resins like nylon. These types of materials are generally used when there is a need for the reduction in noise from the gears.<\/p>\n<p>Since not all transmission problems can be solved with steel or cast iron gears, we provide a comprehensive service in alternative materials:<\/p>\n<ul>\n<li>\u203a FIBRE GEARS<\/li>\n<li>\u203a NYLON<\/li>\n<li>\u203a DELRIN<\/li>\n<li>\u203a BRONZE<\/li>\n<li>\u203a ALUMINIUM BRONZE<\/li>\n<li>\u203a ALUMINIUM<\/li>\n<li>\u203a STAINLESS STEEL<\/li>\n<\/ul>\n<div><\/div>\n<p>These have become firmly established for many applications where exceptionally low noises at high speed, dry running, or safety and wear resistant is required.<\/p>\n<p>A right hand helical gear or right hand worm is one in which the teeth twist clockwise as they recede from an observer looking along the axis.
