CONVUM PBO Vacuum Pads | Oil-Grooved Grip for Inclined Metal Parts

• Oil-Grooved Dual Bellows: Bellows with oil grooves channel surface oil to stabilize sealing on oily parts while providing cushioning and stroke compliance to cut drops and leaks.
• For Sloped/Uneven Metal: Thin lip plus bellows travel conform to angled, curved, or textured metal surfaces, reducing micro-slip under oil film.
• Broad Size Options: ø35 / 50 / 75 / 110 mm to match contact area, payload, and target cycle time.
• No Extra Damper Needed: Intrinsic compliance suits EOATs with tight envelopes where external shock absorbers can't be added.
• Material Choices: N (NBR) for general oil-resistant duty, S (Silicone) softer to minimize marking, U (Polyurethane) wear-resistant with fast rebound—select by oiliness, cleanliness, and surface sensitivity.
• Applications: Oiled sheet-metal handling and stamping lines, automotive panel transfer, oiled coil cut/sort, sloped-part gripping, pallet layer separation, logistics and automated material handling.

Q1: How does PBO differ from the PB series?
A: PBO adds oil grooves to the bellows, improving sealing and anti-slip performance on oily workpieces; PB targets mostly dry or lightly oiled conditions.

Q2: What workpieces are best suited?
A: Oiled metal sheets and stamped parts, as well as sloped, curved, uneven, or textured metal surfaces.

Q3: How do I choose among ø35–110 mm sizes?
A: Size by effective contact area, mass, and desired cycle time; for thicker oil films or slick surfaces, upsize to increase contact and holding stability.

Q4: Do I still need external shock absorbers?
A: Typically no—the bellows provide built-in compliance. Add external damping only for large height steps or unusually high impact.

Q5: How should I select N vs. S vs. U materials?
A: N (NBR) = oil-resistant general duty; S (Silicone) = softer, minimizes marking for mark-sensitive/clean areas; U (Polyurethane) = wear-resistant, quick rebound for high-throughput stations.

Q6: Will heavy oil reduce holding force?
A: Oil lowers friction; PBO's oil grooves help maintain sealing and reduce slip, but tune vacuum flow/throttling and motion profiles, and consider larger pads or more pads for margin.

Q7: Will bellows stroke slow my pick-and-place?
A: Stroke improves compliance; for very short cycle times, validate rebound and vacuum build, then adjust pad size and vacuum settings as needed.

Q8: Is it compatible with existing tooling?
A: Usually yes—check thread/interface type, available stroke/space, and pad OD. Pilot on your tool before full rollout.

Q9: What are the cleaning and maintenance tips?
A: Wipe off oil sludge and dust regularly; avoid prolonged soaking in strong solvents. Replace pads showing lip wear, hardening, or cracks, or when sealing degrades.

Q10: Can PBO handle heavier parts or high-speed transfer?
A: Yes—verify total suction force with a safety margin for your mass/acceleration. Use multiple pads and balanced layouts for heavy or fast moves.
