RENOLD Gears has launched a breakthrough in gear design with its 'new generation' shaft-mounted helical gear units.

Designated the SMXtra, the new series features higher power ratings averaging an impressive 35 per cent over previous models, while optimised design features have permitted original frame sizes and overall dimensions to remain the same.

Allied to the increased power capacity, customer-focused upgrades ensure the gear units are environmentally friendly and easier to fit and configure.

A number of enhanced seal options are available to fit all standard units, which can be installed so as to optimise protection from dust and moisture.

Alternatively, by reversing one element of the standard design, the seal can provide additional security to prevent the egress of oil into sensitive environments - extremely useful for applications involving food production.

Both parallel bore and single taper bush mountings are available. The improved single taper bush, arguably the best taper mounting device on the market, allows for easy removal even after service in the most arduous environment - while a new double taper hub permits fitment of the bush from either side of the gear unit.

For even more convenience, an improved motor mounting platform is featured, which permits side mounting as well as conventional top mounting, and is supplied with a drilling template to suit all matching motor sizes.

Another new feature is the incorporation of a new, compact torque restraint, as an alternative to a conventional torque arm where space limitations apply.

The SMXtra series is available as single or double reduction units and offers gear ratios of up to 25:1 with a power capacity range from 0.3kW to 173kW. Each unit is fitted with high tolerance heavy-duty roller bearings for trouble free running and maximum load carrying capacity.

Applications for the SMXtra are both diverse and comprehensive including conveyor drives, mixer drives, the packaging industry, food process machinery, printing, textiles, materials handling and general industry usage.

The SMXtra comes with a CD ROM containing information on product selection, installation and maintenance. A catalogue 'PDF' file is also included on the CD.
