Shaft Forgings and Forged Shafts Manufacturers

 

The shaft is a cylindrical object worn in the middle of a bearing, wheel, or gear, which is mainly used to support transmission parts, transmit torque and bear loads.

As a leading forged shafts manufacturer, we have professional and advanced equipment to satisfy every customer that we can supply with forged steel shaft with max diameter of 2500mm and max length of 15000mm. In additional, we can manufacture gearshaft in mass with our advantaged large module gear hobbing machine, plus our strict production arrangements and follow-up to ensure that every order can be delivered on time, and when customers have an urgent order, we can arrange the production according to the customer’s demand date.

PRM can provide one-stop solution producing varieties of forging shaft from different types of materials.

Advantages Of Forged Shaft Manufacturing

  • Continuous grain flow, improved microstructure
  • Reduced downtime because of premature failures
  • Increased service life
  • Greater strength & fatigue resistance as to operate at higher pressures and load weight
