S.D. Oscillator

The Camfield Oscillator has been developed to provide smooth, positive, cam controlled rotary-linear combined motions to an external shaft. A compact housing encloses the internal parts and provides (6) different mounting surfaces to suit a wide variety of installations.

The modified construction avoids the necessity of providing openings in the mounting base plate for clearance purposes.

OSCILLATING-LINEAR output movement wherein the output shaft reverses its rotation after each complete linear stroke.

INTERMITTENT-LINEAR output permitting otary indexing after each complete linear cycle. both type allow input shaft rotation in either direction with the corresponding output rotation.

Rotation only-no linear movement

Rotation of the input drive shaft(cw or ccw) causes a track cam and lever to produce linear movement of the output shaft. Positive angular positioning is obtained by the engagement of pair of needle type cam rollers with a hardened and ground guide key(s). Suitable fitting rib cam followers, keeps rotational backlash to minimum necessary for high speed operation and exact angular stopping.

Since the rotational motion is a direct function of the cam stroke, any angular movement less than 180 degrees is obtainable with the addition of a special cam and positional locking rollers. Nonstandard linear strokes and shaft extensions are also available.


  • The Oscillators may be mounted in any position with (6) different mounting surfaces provided. Optional mount bases are available.

  • The output shafts are unhardened to permit customer drilling or reaming operations

  • An optional tubular linear output shaft is available to provide pneumatic, vacuum or electrical accessibility to output tooling.
