About PDL
Pacific Driveline and Henley Engineering 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
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:
Hydro-Turbine
We also supply bearings to the Hydro Turbine Industry:

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
Note: 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
Note:
-
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.
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.
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.
Rodney District Council had XL bearings in an aerator at Warkworth and I understand they went for 10 years plus
SXL used in pump at Fonterra Wharero
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.
