The antibacklash assembly is designed for smooth, quiet operation and long life, providing low drag torque by making use of a patented axial take-up mechanism, creating a stiff spacer that will continually expand to accommodate wear during use. The self-lubricating VHD Series does not require grease to operate and therefore reduces noise and dust in the workplace. Available leads range from 1.27 mm/0.050 to 92 mm/3.6-in. lengths, which go up to 4 m/160 in. VHD Series screws are 303-stainless steel, with an optional extended life coating.
