Stelron RD Series Indexer

The STELRON RD Series Dial Indexer Drive uses the time proven barrel cam as the heart of the drive. Reliable cam indexing technology provides higher speeds than pneumatic and electronic indexing. Cam operated devices require much less maintenance than pneumatic drives, at a fraction of the cost incurred by electronic indexing.

The RD indexer design incorporates the highest degree of application versatility available. One of the standard features include a large through hole for pneumatic, vacuum, and electric lines. The housing is low profile, machined on all mounting surfaces, and provides universal mounting on any of the five sides. The indexing cam is made of the finest quality air hardened tool steel. This tool steel provides deep uniform hardness in a high strength wear resisting matrix. The cams are also CNC profile ground for high accuracy and excellent surface finish. This ground tool steel cam provides remarkable service life for the Stelron RD indexer.

The dial support is a crossed axis roller bearing. This one bearing provides maximum resistance to thrust, radial and moment loading. The rollers are installed in a cross arrangement thereby providing exceptional rigidity to all types of loading. In contrast to " gothic arch " type ball bearings which only provide contact at four points in the ball race, this cross roller bearing provides roller contact over the entire length of the raceway. This bearing does not use a conventional cage to retain the rollers. The rollers are held in the correct location by spacer type retainers. This prevents skewing and friction between adjacent rollers thereby providing smooth, stable, and vibration - free indexing.
