Specifications
Every Turner Uni-Drive gearbox is built with premium materials and precision engineering for demanding industrial environments.

Industrial Gearing
All gearing is case hardened for optimum wear resistance, with pitches selected for maximum strength and finish hobbed or ground for accuracy and quiet running.
- ▶Spur-type gearing is standard, with helical gearing available as an option in applications approved by home office
- ▶All ratios are in stock for quick handling and prompt delivery of emergency replacement orders
- ▶Ground gearing is standard on models sized 10M and above and available upon request for smaller models
Housing
Heavy-duty cast iron or fabricated for maximum rigidity and proper alignment of shafts, gears and bearings.
- •Covers not subjected to transmitted loads
- •Corrosion-resistant for outdoor installation
- •Large surface areas radiate heat effectively
Shafting
Through-hardened alloy steel, splined for maximum torque transmittal through gearing.
- •Keyways conform to ASA standards
Shifting
Rugged internal shifter forks of cast iron or steel held in position with spring-loaded detents.
- •Positive locking device available for severe vibration
Bearings
Heavy Duty tapered roller bearings used throughout.
- •Adjustments made easily without removing case cover
Seals
Spring loaded lip-type cartridge seals at all shaft extensions, including shifter arms.
- •Maximum protection against oil leakage
- •Magnetic pipe plugs remove metallic particles
Lubrication
Splash lubricated gears and bearings for normal mounting.
- •Sight gauge for easy oil level checks
- •Efficient air breathers equalize pressures
- •Optional pump-driven circulating oil system with heat exchanger

Options & Add-Ons
Industrial Transmission and Gearbox Accessories
At Turner Uni-Drive we take pride in flexibility. Our aim is to exceed your expectations. We will accommodate your requests for options and accessories — from the highly technical to the most obscure.
Standard Rigid Mounting Bases
Rigid mounting bases are used to mount under the gearbox and raise it to an efficient operating level. This option is typically selected to accommodate pulley size and motor alignment.
Custom Mounting & Machine Bases
Turner Uni-Drive will custom manufacture mounting plates and machine bases to meet your requirements. Typically selected for retrofit applications to provide ease of installation or to incorporate the motor, transmission and other components on a single base.


Hinged Motor Plates
Hinged motor plates provide a mounting surface for the motor on top of the gearbox. They are adjustable to allow for belt tensioning and to reduce installation space requirements for the motor and gearbox.
Helical Gearing
Helical gearing is typically selected for higher horsepower applications with a higher load-carrying capacity and quieter operation than standard spur gearing. Combined with gear grinding capabilities, helical and ground gears produce an exceptionally quiet-running gearbox.


Pneumatic Shifting
Pneumatic shifting is accomplished via internally mounted air cylinders and external solenoids provided in a variety of voltages. Shifting is typically accomplished at a remote location or operator's control panel. Shop air of 35 to 45 psi is required.
Proximity Sensors
Proximity sensors are mounted in the housing to detect the location of shifting components. This option is selected with or without pneumatic shifting to provide positive assurance at the control panel of a complete shift.

Lubrication Systems & Heat Exchangers
Shaft-driven or independent lubrication pumps and heat exchangers are available for unique applications. Lubrication systems may be necessary for unique mounting systems, for example, to lubricate vertical units. Heat exchangers are used to lower the overall operating temperature of a gearbox. This is only a partial listing of options available — we will gladly accommodate other requests.
