All Welker Part Positioners require application approval.
Application approval form can be found in the ejector catalogs.


LST Part Positioner

Part positioners can increase robot access and reduce tool size and controls logic complexity

LST features a compact design, providing two motions for one cylinder. A choice of fixed tip angles: 11°, 22°, 31°, 39°, 45°. Treated steel tip plates provide weld spatter and corrosion resistance for durable operation in extreme environments.

Integrated 70mm or 100mm bore pneumatic cylinder.
Optional solid state cylinder switch, world switch, V-block switch.
Minimum 2-second cycle time.


SST Part Positioner

Part positioners can provide substantial savings over traditional overhead locating and clamping constructions

SST is a smaller version of the LST, with the same load capacity. Tip angle is fixed at 30°.

Integrated 70mm or 100mm bore pneumatic cylinder.
Optional solid state cylinder switch, world switch, V-block switch.
Minimum 2-second cycle time.


MST Mini Part Ejector

MST is suitable for horizontal applications

MST offers the proven quality and durability of standard positioners, ideal for smaller applications. The MST’s tip plate lifts up 30mm and tips out 30°. The unit is capable of handling loads up to 30 lbs. with a maximum torque of 100 in-lbf.

Integrated 50mm bore pneumatic cylinder.
Optional solid state cylinder switch, world switch V-block switch.
Minimum 2-second cycle time.


S01769 Part Positioner

Monster positioner delivers 1600 lbf of clamping force at 80 PSI

S01769 is a heavy duty part positioner, featuring tip angles of 20-45° in 5° increments.

Integrated 150mm bore pneumatic cylinder.
Optional solid state cylinder switch or world switch.
Minimum 2-second cycle time.
