About Indexing & Indexers

Indexing is the repetitive movement of a

mechanical element, from an initial position

(starting from a rest position also known as dwell)

to a new position. In other words, it can also be

defined as the process of starting and stopping

the motion in precise intervals at precise

locations. Indexing is applied generally to either

linear or rotary applications.

Cam Driven Indexers convert constant rotary

motion at the input shaft into intermittent rotary

motion at the output shaft.

This motion is achieved by the combination of the

Cam, driven generally by a motor and reducer, and a Turret attached to the output shaft which

contains the cam followers. The whole assembly is generally enclosed in an oil filled box known

as Housing.

As the cam rotates, followers on the follower wheel are guided through a path dictated by the

shape of the cam. During specific portion of the input rotation, the cam confines the followers

(and therefore, the output) to a rigid, stationary position called Dwell. During the remainder of

the camshaft rotation, the cam geometry causes the followers to move and the output to

rotate. This movement is called an Index.

The turret can be made to Index round between stopping positions or oscillate between two

stops. The cam can be stopped and restarted when the turret is at rest to extend cycle times. As

the cam is rotated at a constant speed, the output stops and starts (i.e. dwells and indexes) in a

repetitive pattern.

When turrets are required to index first one way then the other, the mechanism is called as an

‘Oscillator’.

GLOBOIDAL CAM INDEXERS & OSCILLATORS - RS/RF Series

These series of indexers are robust, versatile units suitable for a wide variety of applications and

basically comprise of two elements, the Globoidal cam and radially equispaced cam followers

called Turret. Available as Shaft output (RS) and Flange output (RF), in many sizes to meet a

wide variety of speed, load and space requirements.

• Centre distance : 45 to 250mm

• Number of stops : 2 to 36

• Index angle : 90º to 330º

• Oscillation angle : 1º to 180º

• Accuracy : ±30 Arc seconds

• Optional centre thru-hole in flange version

ROTARY TABLE INDEXERS - RX Series

The RX series adopts the same mechanism as in RS/RF series but the larger turret diameter is

more suited for high number of stops indexing applications. The RX series is ideal for rotary dial

applications with features including large output mounting surface & large centre thru-hole.
