Spring-loaded vacuum cup suspension assemblies SLSA-2 series (G 1/8″ thread), rotating and non-rotating compensators, plus a G 3/8″ rotating and non-rotating compensator
Manufacturer PDF

ANVER vacuum suction cups can be mounted to most vacuum systems using spring-loaded suspension assemblies. These are high-quality, well-finished assemblies designed for high-speed automation applications. The suspension assemblies have adjustable bulkhead fittings that mount to almost any lifting frame, and a variety of tube fittings are available to connect the spring-loaded assembly with the vacuum generating system. These unique mounting systems act as extensions while providing support when handling loads.
Advantages of suspension assemblies
- Reduce machine indexing when picking up material from a stack
- Compensate for variations in object height and offer a soft touch attach
- Minimize shock and noise to an object and machine
- Provide consistent cup pressure on each pick up, which increases cup life
- Easy way for vacuum cup and vacuum lines to interface with machine tooling
ANVER’s SLSA-2 Series connects to a vacuum system via G 1/8″ NPS (fits into 1/8″ NPT) male thread.
For 5 mm, 10-32 UNF threads, use the SLSA-1 Series.
ANVER can adapt these vacuum cup suspensions to your particular needs with tube fittings, mini vacuum generators, sensing valves, and custom adapters. Please contact our technical sales team for assistance.

Tube fittings for SLSA-2 series vacuum cup suspension assemblies
Tube fittings are purchased separately to connect the spring loaded suspension assembly to the vacuum hose. They are available in barbed, push-in, and compression connections, with straight, elbow, and tee configurations. These fittings accept tubes with standard inside and outside diameters.
