Sterling Instrument, an ISO 9001:2000+AS9100B-registered manufacturer, has introduced a series of right-angle EG planetary gearheads.

The sealed gearheads are offered in four standard NEMA sizes (17, 23, 34 and 42) and feature a planetary system, high torsional stiffness and case-hardened spiral bevel gears.

They offer single- and double-stage design and include a precision-balanced clamp-on pinion.

Woodruff keys #404 and motor mounting hardware kits are supplied.

Each of the four NEMA sizes is offered in 13 gear ratios, ranging from 3:1 to 100:1.

The maximum input speed of the gearheads is 5,000rev/min and their radial and axial shaft loading is 400lb (181kg).

Their single-stage and double-stage minimum efficiency is 85 per cent and 80 per cent respectively.

Operating temperatures range from -40F to +225F.

The housings are made of steel and are gold zinc plated.

The right-angle housing and mounting flanges are made of aluminium and are black anodised.

Stock Drive Products/Sterling Instrument offers NEMA inline gearheads, NEMA right-angle single-output gearheads and NEMA dual-output gearheads all in sizes 17, 23, 34 and 42.
