Silicone vacuum cups for robotic woven-bag handling and bag-opening equipment. Choose QLF68 or QLF90 to match the required cup diameter and mounting dimensions.
- Available cup diameters: 68 mm and 90 mm
- Individual dimension diagrams are provided for each model
- Ribbed cup body supports flexible contact with bag surfaces
- Confirm the model and mounting dimensions before ordering
QLF68 vs QLF90: model selection
- QLF68: 68 mm cup diameter; check the QLF68 dimension drawing for the mounting interface.
- QLF90: 90 mm cup diameter; check the QLF90 dimension drawing before substituting it for another cup.
Both listed models are silicone vacuum cups for robotic woven-bag handling and bag-opening equipment. Diameter alone does not confirm a replacement fit. Compare the existing cup, available contact area and mounting dimensions with the selected model.
Checks before ordering and installation
- Keep the cup contact area clear of bag edges and seams.
- Check sealing on representative woven-bag samples; surface texture and leakage can vary.
- Verify vacuum build-up, grip and release through the actual machine cycle.
- Do not infer a load rating, thread size or universal machine compatibility from the nominal diameter.
For the selection process, see the bag-opening vacuum cup guide. If the mounting is uncertain, send the existing cup dimensions and bag application for review before ordering.
