And we can combine left and right hand threads on a single shaft for together + apart motion.

Our lead screws are 303 stainless steel, except the 5 and 10 pitch (Code: W1, W2 and P5, P10) lead screws which are electroless nickel plated, cold rolled steel.]]

Characteristics Of Lead Screws

  • A lead screw nut and screw mate with rubbing surfaces, and consequently they have a relatively high friction and stiction compared to mechanical parts which mate with rolling surfaces and bearings. 
  • Leadscrew efficiency is typically between 25 and 70%, with higher pitch screws tending to be more efficient.
  • The high internal friction means that lead screw systems are not usually capable of continuous operation at high speed, as they will overheat. 
  • Lead screws are typically used well greased, but, with an appropriate nut, they may be run dry with somewhat higher friction. There is often a choice of nuts, and manufacturers will specify screw and nut combination as a set.
    The mechanical advantage of a lead screw is determined by the screw pitch and lead.
  • A lead screw will back drive, whereby forces on the nut applied parallel with the lead screw will cause a free-moving lead screw to begin to rotate.

Advantages

  • Large load carrying capability
  • Compact
  • Simple to design
  • Easy to manufacture; no specialized machinery is required
  • Large mechanical advantage
  • Precise and accurate linear motion
  • Smooth, quiet, and low maintenance
  • Minimal number of parts

Disadvantages

Driver Shaft


Saraswati Manufacturing Works is worldwide leading manufacturer of Driver shafts which are in wide demand in the markets. To make these Shaft raw material used is mild steel, EN-8 steel, seamless pipe and synthetic rubber pipe, which are procured from the reliable vendors of the markets.

A Drive Shaft, Drive Shaft, driving shaft, pro peller shaft,shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.

Our range of drive shafts undergo rigorous tests at different steps of manufacturing to ensure their compatibility with desired applications. We use latest technology and machines, which makes our shafts widely demanded in automobile industries.

We have a well equipped research & development unit where our team members are involved in the development of products as per the current industrial standards.
