  • How to select Casters and Wheels
    with five different wheel bearings, which exert a great influence in their performance. They are: plain bearing, nylon socket, bronze socket, roller bearing and ball bearing. For light duty loads and low handling requirements, the plain bearing or nylon socket wheels are the most suitable, providing

  • Flywheel Housings and Flywheels
    Handling Description: Mounting parts onto an engine. Problems: Very heavy parts being mounted to an engine on a hanging conveyor and engines are allowed to sway. Operators had to crawl under the engine to insert shields onto installed housing with only 6" clearance. Requirements: * Housings

  • Spinning Mass Mechanical Gyroscopes
    . (precession in – torque out). The rate in – torque out relationship is the basis of the rate gyro. The spinmotor is mounted in a gimbal that is attached to the gyro case by a torsion bar on one end and a precision. bearing at the other end. The torsion bar limits the rotation of the gimbal. The gimbal
  • Mechanical Motion Keeps Pace
    , lighter-duty industrial packaging applications in 200-230 Vac systems have speeds to 1 m/sec and positioning repeatability +-0.02 mm. Non-rotating stainless-steel piston rod actuators operate without externally mounted limit or home switches, retaining position during a power loss for faster
  • Medical Device Link .
    actuator incorporates engineering thermoplastics in the rotor drive nut and a stainless-steel acme leadscrew. This makes the motor more efficient and durable than the commonly used v-thread and bronze-nut configurations. An additional feature is a bearing-preload adjustment that does not protrude from
  • Know Thy Press: In Sickness and in Health
    valve type fitting. These bushings have graphite impregnated into the bronze. These bushings require very little maintenance. The use of Mobil Viscolite or similar is best, but only a small amount is needed to spread the graphite onto the rod, coating the rod black and somewhat dry. Never put grease
