The STELRON Index Drive, Dial Drive, and Parallel Drive include many important features to enhance durability, serviceability, and accuracy to your stelron drive. Some of these important features include: Hardened and CNC profile ground, extra large diameter cams operating in a sealed, oil filled housing, Standard NEMA “C” frame motors, Heavy cast aluminum universal mounting housings with machined surfaces and mounting holes on five or six sides, and Heavy Duty swing arm type micro switches with large diameter steel signal cams. Stelron indexers are equipped with two types of overload protection: 1) Internal Output Clutch ( RD series ). 2) External Output Clutch ( RS series ). 3) External Output Clutch ( M series ). 4) Internal Input Clutch in Gear Reducer.
The STELRON Machine Chassis is available in 5 configurations including the CWB, RWB, WB, O/U PLC, PLC, and RAD. Various features include Synchronous / Non-synchronous palletized assembly system provides the greatest flexibility while maintaining high speed assembly, Versatile friction conveyor transfer between walking beam units allows manual access to both sides of the pallet (the conveyors may also serve as a short term accumulators), Reliable cam driven walking beam, Accurate shot pin locking beam, Single lane pallet transfer or dual lane pallet transfers with independent drives, Recirculating end units with independent drives and corner overload protection, Below the pallet access, Optional mounted precision pick and place and other cam driven motion devices, STELRON SBGR right angle drive unit with integral slip clutch and single position output overload clutch.

The STELRON Translator provides two independent linear axis of cam controlled movement. Any motion in a single plane (within the stroke and minimum cam angle limitations) is possible. The end plate, or output, is guided by precision linear bushings. The spread, or aspect ratio, of these bushings has been maximized for optimum stability, life and freedom from unwanted movement (shake) of the output member. The “X” axis cam follower is located on the carriage block and directly engages the “X” cam. This enhances the load capacity of this axis. The “Y” axis provides motion to the endplate through a needle bearing supported bell crank mechanism and a yoke assembly. Since the translator utilizes a track cam, some backlash can be expected. Consult Stelron for methods to minimize or eliminate backlash at the end positions. The Translator mechanism is housed in a rigid cast aluminum housing that can be mounted in any position.
The STELRON Trans-Part has been developed to provide smooth, positive, cam controlled rotary-linear combined motions to an external output shaft. A compact housing encloses the internal parts and provides (5) different mounting surfaces to suit a wide variety of installations. The STELRON FJ SERIES TRANS-PART has been designed to permit mounting to a surface where the standard lower bearing shaft projections are undesirable. The modified construction avoids the necessity of providing openings in the mounting base plate for clearance purposes. This has been accomplished with only minimal reductions in the maximum linear or rotational strokes for the 6 standard sizes available. The FJ Series eliminates lower shaft and bearing projections for improved mounting applications while all other applications remain unchanged. Maximum axial and rotational strokes are only slightly reduced. In Addition, all external dimensions remain unchanged except for the P, Q and R dimensions.
STELRON Vari-Pak provides an integral, compact means for linear “pick and place” operations. It is available in five different sizes with two series of VARIABLE stroke ranges to accommodate a variety of applications. The user may also obtain the unit in standard FIXED stroke sequences. The STELRON “SVIP”Vari-Pak is now available with spring operated “forward and downward” movements, combined with a positive return. This feature protects expensive tooling as well as the unit itself when a “jam-up” or other malfunction occurs. The positive return guarantees that the tooling plate retracts to avoid interference with other moving parts. In addition, exact repeatability of tooling is assured by the elimination of any mechanical backlash or play for critical “pick & place” applications. Extra length compression springs assure long life and minimum energy variation. Since the “SVIP” unit is identical in all external dimensions to the widely accepted “VIP” Vari-Pak, complete dimensional data, capacities, and sizes may be obtained by referring to our catalog.
