Technical Details
The Series G helical industrial gearboxes have been introduced to meet the requirements of today's demanding applications in the medium and heavy-duty sector of the power transmission market. Innovative modular design technology has minimised manufactured part count to maximize availability of product.
Gear tooth geometry design combines maximum efficiency with high load carrying capacity and minimal noise generation. Serviceability of the product was key in the design of the Series G range allowing easy maintenance for long life and reliability, which are synonymous with our field reputation.
Available as right angle or parallel shaft arrangement, with solid or hollow output sleeves. With optional integral backstop.
A range of motor adaptors are available for alignment free motor fitment, units can also be supplied fully assembled on a fabricated steel baseplate.
Cast iron case available as standard, with SG iron and fabricated steel cases available against special order.
Features & Benefits
This product takes advantage of our many years of accumulated design expertise together with the use of high quality materials and components, and has the following features & benefits:
- Case hardened and ground helical gears, and hard finished spiral bevel gears have optimised gear geometry to maximise strength and efficiency, and to minimise noise and vibration.
- Horizontal split case design for ease of maintenance.
- Large diameter output shaft and bearings to maximize overhung load capacity.
- Innovative modular construction has minimised part count to maximise availability of product.
| Features | Benefits |
| Lip, Labyrinth and Face Seal on input, Lip Seal and Labyrinth on output shaft | Better sealing for harsher environments |
| Vertical units have a Drywell sealing arrangement | No head of oil resting on the output seal |
| Spherical roller bearings throughout (tapers roller bearings on bevel pinion shaft) | Provides longer life |
| Large diameter output shaft, higher over hung loads | Best option for stirrer applications |
