Suction cup BL50-2 Chloroprene

The same applications as for short bellows but can cope with greater differences in levels due to the longer lifting movement. Not suitable for use with deep vacuum levels. Can be equipped with reinforcement rings of polyamide to give extra stability. Can be used at a wide temperature range.

Description

The same applications as for short bellows but can cope with greater differences in levels due to the longer lifting movement. Not suitable for use with deep vacuum levels. Can be equipped with reinforcement rings of polyamide to give extra stability. Can be used at a wide temperature range.
Features
- Suitable for level adjustment.
- Lifting movement to separate small and thin objects.
- Less suitable when the lifting force is parallel to the surface of the object.

FAQ

How do I know which lifting forces I need?

It depends on the weight of the product that should be lifted and how many suction cups that can be used for the object. Calculate the weight to be lifted per suction cup and then take the weight multiplied with the gravity force (g = 9,81) and you have the lifting force needed in Newton (N).

How do I know which suction cup to choose?

Our recommendation is to start at the application listing to find the products we recommend to different applications. If you have questions please do not hesitate to contact our partners to find the optimum solution.

How should Piab suction cups be stored?

Please see our storage guidelines:

Storage guidelines of suction cups and rubber products (pdf)

I have a variation of number of objects to be lifted - how can I make sure to not drop them or to use too much energy? How to optimize this type of system?

All suction cups not in contact with an object (open) will draw in a lot of air and demand a larger pump than actually necessary. By using different valves, such as piSAVE® sense, in the suction cups, the suction cups will be normally closed until they come in contact with the handled object. Only the cups needed in the specific lifting cycle will be open and flow air. Please see the video piSAVE® sense.

What is DURAFLEX®?

DURAFLEX® is a patented material specially developed to feature the elasticity of rubber and the wear resistance of polyurethane. The DURAFLEX® material is mark-free.
