Why Tubular Shafting?

• Eliminate difficult alignment of multiple bearings on solid shafting.
• Eliminate exposure of bearings to wet air streams that result in subsequent 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.

• Delivery
• No minimum quantity for fast shipment.
• Breakdown service on single shaft orders.
• P.T.S. offers computerized shaft selections.

Why P.T.S. Shafting?

• 1st with the quality 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" 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 PTS shaft increasing its natural frequency or critical speed up to 20% — a safety factor for your equipment design. Suitable for temperatures to 350°F

Let PTS help show you how to lower cost through standardization.
