New Hyde Park, NY — A new series of right angle EG planetary gear heads from Sterling Instrument (ISO 9001:2000+AS9100B Registered Manufacturer) features low cost, and is offered in four standard NEMA sizes, 17, 23, 34, and 42. These gearheads, identified as the S91..SREG.. Series, feature the planetary system, high torsional stiffness, case-hardened spiral bevel gears, and are sealed to extend service life. They offer both 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. Their maximum input speed is 5000 rpm. Their radial and axial shaft loading is 400 lb. Their single stage and double stage minimum efficiency is 85% and 80% respectively. Operating temperatures range from -40°F to +225°F. The housings are made of steel, gold zinc plated. The right angle housing and mounting flanges are made of aluminum, black anodized.

New Hyde Park, NY – A new series of slit type plastic couplings from Sterling Instrument features low cost, UV resistance, voltage and RF isolation. 
These couplings, identified as the S50TLC… Inch and Metric Series are stocked in sizes 13, 19 and 25. These lightweight molded patented couplings can replace stainless/aluminum slit type couplings with lower cost and improved operation with no windup or backlash or any derating for reversing applications. It uses a metal screw-to-metal nut design to insure a tight fit between the shaft and the coupling, and does not use threads cut into the molded piece.
These couplings are made of engineered polymer and have stainless steel fasteners. Bore sizes range from 0.125 to 0.500 in. (3 to 12mm). They range in length from 0.710 to 1.400 in. (18 to 36mm) with a maximum temperature range of -4°F to +284°F (-20°C to +140°C).
The couplings can be used in a variety of applications and are especially able to accommodate tight or skewed connections. Quotes, online orders, available stock, and 3D CAD Model downloads are available at our new eStore at: www.sdp-si.com/eStore
