Fan Shafting

  • Eliminate difficult alignment of multiple bearings on solid shafting.
  • Eliminate exposure of bearings to wet air streams that result in subsequent fan shaft failure.
  • Eliminate the high cost of solid shafting and multiple drive and bearing arrangements.
  • Eliminate internal structural support members that hinder correct air flow patterns and are costly to fabricate and install.
  • Eliminate multiple stocking of fans with various bore sizes.
Why Pittsburgh Tubular Shafting

Why Pittsburgh Tubular Shafting?

  • 1st with the quality that the shafting industry demands
    Integral swaged journal design
  • Extra heavy journal on the drive end to assure maximum torsional strength
  • Practical tolerances
    Balanced to perform
  • Compensation for static-kinetic and 
2 plane dynamic unbalance are standard PTS design
  • Insures straight thru-production
  • All balance weights are applied internally
  • No obstructions to slow assembly
  • Exclusive "Rigitized" shaft design
  • The standard PTS shaft is injected with near weightless urethane foam, forming a solid core. This foamed in place urethane dampens the resonant frequency of the Pittsburgh Tubular Shafting's shaft increasing its natural frequency or critical speed up to 20% — a safety factor for your equipment design. Suitable for temperatures to 350°F
