FAQ for carbide grippers:
Q1: What are carbide grippers?
A: Industrially known as cemented carbide slip inserts, carbide grippers are sintered tungsten carbide-cobalt components (tungsten carbide matrix bonded with cobalt binder). Their surfaces are precision-machined with anti-slip serrated teeth, and most variants are silver-brazed onto a 45# or 40Cr steel substrate. Relying on their ultra-hard, wear-resistant tooth profiles, they clamp drill pipes, casings, metal bars and shaft workpieces. They are divided into three core application types: slips for oilfield wellheads, chuck jaws for CNC lathes, and gripping inserts for automation robotic grippers.
Q2: How to select carbide grippers grade and their applications?
A: For YG-series carbide: higher cobalt means better toughness and impact resistance; lower cobalt means higher hardness and better wear resistance.
YG6: Low cobalt, HRA 90–91, high wear resistance. Suitable for light-load, impact-free smooth clamping pads; not for toothed load-bearing slips.
YG8: General-purpose balanced grade. Ideal for standard oilfield drill pipe slips and common steel pipe clamping. It is the most widely used grade.
YG8C / YG11C: Coarse grain, high toughness. For heavy-duty drilling, burr workpieces and frequent impact clamping, anti-chipping performance is excellent.
YG13C / YG15: High cobalt, maximum impact resistance. Used for large drill collars, downhole packer anchors and heavy mining clamps to prevent tooth breakage under severe impacts.
Q3: Do you support non-standard customization of carbide grippers?
A: We support customization based on provided drawings or samples; customers must supply complete specifications:
Q4: What’s the minimum order quantity (MOQ)?
A: Standard stock sizes normally require 3kg MOQ. Non-standard customized shapes require higher MOQ to cover mold & sintering cost.
Q5: What is the production lead time for carbide grippers?
A: In-stock carbide gripper inserts: 2–3 working days.
Standard custom orders: 10–25 working days.
