The basic function of a power transmission coupling is to transmit torque from an input shaft to an output shaft at a given shaft speed and, where necessary, to accommodate shaft misalignment. Misalignment is the result of many factors including installation errors and tolerance variations.

Designed to convert rotary motion into linear motion, Roh'lix Linear Actuators are ideal for positioning operations in all types of machinery. Available in 5 different sizes from 5 to 200 pounds thrust.

From the smallest Model 200 SAE "A" mount to the largest Model 1500 SAE "F" mount, OHLA's feature rugged housings of cast iron, shafts of 130,000 PSI stress-proof steel, ball or taperedroller bearings, many different shaft options and attractively painted housings.

Torq-Tenders are positive drive couplings which provide accurate overload protection in many mechanical power transmission systems. When a jam-up or excess overload occurs, Torq-Tenders disengage motor drives.

The Phas-Lok Adjusting Hub is an economical, yet precision device. It provides an easy way to change the phase relationship of a drive component and the shaft. It is ideal for fine tuning timing adjustments, adjusting for chain elongation, and sprocket toothwear.

Servo motor applicationsare more demanding than ever. The precision positioning requirements and high reverse load characteristics of AC and DC servomotor applications necessitate a coupling design that specifically addresses the needs of these sophisticated systems.

High speed rotary fabricating and die cutting machinery employ phase adjusting differentials connected by means of backlash-free CD® couplings from Zero-Max. The couplings damp out any backlash or harmonic tendencies that might occur in the system.

Designing the first of its kind, automatic, 5-panel wrap around case packer for juice cups with simultaneous stacking of three high incoming juice cup lanes required a new approach for Schneider Packaging Equipment Co., Inc. and its customer Jersey Juice, Inc. of Ewing, New Jersey.

Servomotor powered indexing stations in automated pouching systems require accurate registration as they position, fill and heat seal completed pouches. Case in point are the new standup pouching systems by Robert's Packaging that fill and seal stand-up pouches from roll stock at up to 220 pouches a minute with food products such as potato chips, rice, candy, nuts and pet food.

Find out how Auger systems using direct drive servo motors for blending and filling food pouches and packages are an improvement over stepper motor and traditional clutch/brake systems resulting in increased speed, repeatable filling accuracy and reduced system maintenance.
