In-line helical gearboxes add 5000h life bonus

NBC Group, UK distributors for Italian gearbox manufacturers Varvel, is pleased to announce the launch of the new in-line helical RD series gearbox. Manufactured to ISO 6336/Din 3990 size standards, the key benefit to the consumer is that each unit has been designed around a 15,000 hour life at service factor SF1. Other manufacturers only design around 10,000 hours, thus Varvel offer 50% more life at prices competitive with manufacturers already using the ISO 6336 footprint for their in-line helical units.

There are 5 different size options, offering 28 ratios through 2 and 3 stage reductions.

Powers range from 0.06kW to 9.2kW, ratios from 2.5:1 to 630:1 with output torques from 1.0Nm to 635Nm.

Another key benefit for the consumer is that the units are compatible with standard IEC frame size motors, offering greater flexibility and less expense to the replacement user(no more special motors) and a more familiar territory for the design engineers! The housings are pressure die cast to AISI 12 Cu2Fe, with the gears manufactured in steel 20MnCr5 case hardened.

Varvel have been manufacturing gearboxes since 1955 and currently produce 600 gearboxes daily at their plant in Crespellano in Italy.

A family run firm, they have the ability to offer a flexible, individually orientated service which mirrors that of the NBC Group, who were founded in 1956 and distribute Bearings and Power Transmission products through 4 divisions in the UK - OEM, Export, Distribution(trade only), and the Replacement division.
