Sulzer Projectile Gripper D1 2.2x3 2.2x4 3.8x5 D2 4x5 Alloy Steel Replacement Part for Loom Picking
These are Sulzer projectile grippers from the D1 and D2 series, supplied in four sizes: D1 2.2x3, D1 2.2x4, D1 3.8x5 and D2 4x5. The projectile is the part that carries the weft across the shed on a projectile loom, so its balance, its clamping face and its flight profile decide whether the pick lands cleanly or not.
Each projectile is precision-balanced and heat-treated to withstand high-velocity picking. That matters because the projectile is accelerated and stopped by impact on every single pick, thousands of times a shift: an unbalanced or soft projectile starts to fly off line, wear its guide and damage the yarn at the shed edges long before it fails outright.
Four sizes are stocked so the gripper can be matched to the loom width and weft count rather than forced to fit. The D1 series covers 2.2x3, 2.2x4 and 3.8x5, the D2 series covers 4x5; please confirm the size marked on your existing projectile or in the loom manual when ordering.
Centrosymmetric design: the clamping surface is smooth and the clamping force is stable, so the weft is held consistently from pick to pick
Streamlined design: 45 degree diagonal smooth transition with a spherical streamlined head, so the projectile runs stably with low resistance during flight
High-quality alloy steel with vacuum heat treatment and surface nitriding: high fatigue strength, wear-resistant and rust-proof, long service life
Precision grinding and polishing: fine polished surface, elegant and attractive finish
Every projectile is precision-balanced and heat-treated to withstand high-velocity picking

Q1: Which size do I need for my loom?
A: The four sizes are D1 2.2x3, D1 2.2x4, D1 3.8x5 and D2 4x5. Check the marking on your existing projectile or the loom manual, and tell us your loom model; our sales team will confirm the size before shipping.
Q2: Are these original Sulzer projectiles?
A: No. They are aftermarket projectiles made to the original dimensions, balanced and heat treated to the same working duty, but not Sulzer-branded.
Q3: Why does the heat treatment matter?
A: The projectile is accelerated and stopped by impact on every pick. Vacuum heat treatment plus surface nitriding raises fatigue strength and wear resistance, so the projectile keeps its shape and its clamping force over a long service life instead of peening and going out of balance.
Q4: What is the minimum order quantity and the lead time?
A: MOQ is 2 pieces and the delivery lead time is 1-3 days after order confirmation.
Q5: Is the projectile inspected before shipment?
A: Yes. A video outgoing inspection is recorded for every batch and can be sent with the shipping documents.
Q6: What warranty do you offer?
A: 6 months against manufacturing defects. Damage from wrong size selection or use outside the intended loom application is not covered.
Q7: Do you support neutral or private-label packing?
A: Neutral packing is standard. Private-label carton marking and artwork are available on request; please confirm details with sales before shipment.
