Pacific Driveline and Henleys Propellers Overview

Following is an over view on what both Pacific Driveline and Henleys Propellers do. – as well as Thordon bearings of course. 
In a nutshell Pacific Driveline (PDL) handles Twin Disc gearboxes and controls, while Henleys handles everything aft of the gearbox to back past the propeller to the rudder. Both Companies supply Thordon bearings and manufacture and repair, props, pump impellers and stirrers.



 
 Gearbox on a test-bed at PDL   Henleys-from the half coupling back to the rudder


At Henley's we design and build props, p- brackets, rudders, tiller arms, rudder ports, shaft seals, half couplings, shafts and shaft housings. We look after a range of sizes:



 
 
Big stuff -Inter-Islander ferry blade
  5 bladed launch propeller. 
   10” diameter Thunder-cat racing prop
         

 
 
 Bearings for Pumps     Refurbished 30” Ø Pump impeller    Worn cutlass bearing
         
 
 
Peak cap bearing for Sedimentation    Tank in Sewage treatment plant.    Isoflex Engine Mounts 

 

With the exception of the Inter-Islander ferry blade, all props and impellers can be scanned the prop scanner. We will Repair, Tweak and Balance to as good as new or better any prop or impeller.

 


 



Hydro-Turbine

We also supply bearings to the Hydro Turbine Industry:

 
 Hydro Power Station    Tuai G1 ThorPlas wicket gate bearings
     

 
 Lake Coleridge ThorPlas 
Wicket Gate bearings
  Thordon SXL Main Guide Bearings
for Fereday Island Kaplan Generators.



Other ThorPlas bearing Applications


Forestry – Handling & Transportation

End User: Timrick Slashers (Canada)
Application: Slasher Grapple Bearing – Forestry
Installation Date: March 2005
Note: Robotec Grapple (OEM) - Can pick up tree length at lengths up to 60’. Replaced bronze bearing.



Scrap Metal & Recovery

End User: Berman Brothers, FL. USA.
Application: Grapple Bearing -Scrap Metal, Recycling
Installation Date: December 2003
Notes: Nylon bearings lasting only 2.5 weeks. ThorPlas bearings lasted 5 months before unit was sent for repairs (no issues with bearings).




Mining – Truck Stabilizer

End User: Mining Facility Peru
Application: Steady Axle 100 Ton truck 
Installation Date: March 2005

Note: 
  • Initial bearings were bronze, lasting 2500 hrs. Replaced it with Nylon that lasted 7000 hrs. Currently, ThorPlas CONTINUES to operate without issues (>13,000 hours)
  • Grease lubricated but can not guaranteed continuously.
  • Large bearing sizes 348 mm (313.7”) x 327.5 mm (12.9”) x 101.6mm (4”)

 

 

Forrestry – Kiln Drying

Application: Sawmill carrying container- wheel bearings. Pulp & paper industry (Chile)
Installation Date: January 2006

Notes: 

  • Bronze bearings lasting only 2 months. ThorPlas bearings inspected after 5 months. Minimal wear found – expected service life of 10 months based on wear.
  • Hot temperatures & humidity in excess of 176°F (80°C) for short periods. 
  • Pressure >13.7 MPa (2000 psi).
  • Anti-rotation pin placed on top of the bearing caused cracks yet bearings continued to operate without any issue.

 

 

Oxidation Pond Aerators

The self aligning bearings on the aerator below only lasts 18 months before they are rusted out and need replacing. They also need grease lines and regular greasing.



 

Using Thordon SXL flat top bearings in this application as pictured below will do the following:

  • You will eliminate grease lines and the need to regularly grease.
  • Extend out the life of the bearings. 
  • Because the bearing issplit, it will offer easy maintenance as the gear box and motor will not have to be taken off the shaft to replace the bearing. 
  • Splashing of the water by the aerator will lubricate the bearing.

Rodney District Council had XL bearings in an aerator at Warkworth and I understand they went for 10 years plus


 

 

Typical Thordon Applications


 
 SXL used in pump at Fonterra Whareroa    Screw Conveyor bearings



Flo Mo Meat Pump at Graeme Lowe Offal Plant

SXL used in a Flo Mo Meat Pump to replace needle roller bearings.

SXL makes it easier to dismantle the meat pump for cleaning and also stands up to CIP cleaning practices.
