Stainless Steel Anti-Bend Gland
The Stainless Steel Anti-Bend Gland (also designated as a strain relief cable connector with an integrated spiral guard) is engineered for dynamic machinery, high-vibration control cabinets, and corrosive outdoor installations. Designed to distribute bending stress uniformly and prevent sharp cable radii at the entry point, it protects power and control lines against core fatigue. Machined from solid stainless steel bar stock, this component delivers high mechanical retention and long-term sealing stability in demanding industrial environments.

Key Features
Solid Machined Body: Fabricated from solid AISI 304 or AISI 316 stainless steel bar stock, offering high resistance to chemical agents, saline atmospheres, and mechanical impact.
Spiral Spring Guard: Flexible stainless steel tail spring prevents over-bending and kinking, distributing mechanical loads evenly across continuous flexing cycles.
IP68 Ingress Protection: Precision-molded NBR/EPDM sealing insert and O-ring achieve an IP68 rating, ensuring dust-tight and submersible performance up to 5 bar.
Positive Strain Relief Clamping: Internal clamping claw secures the cable jacket firmly, preventing pull-out or slippage under heavy axial tension.

Frequently Asked Questions
Q: How do I select the correct thread size for my enclosure?
A: Match the thread standard (Metric, PG, or NPT) and nominal diameter of your panel knockout or tapped hole. Refer to our technical specifications table for exact thread major diameters and pitch dimensions.
Q: What cable diameter range does a specific gland accommodate?
A: Each gland model specifies a tight clamping window (e.g., M20x1.5 fits cable outer diameters from 6 mm to 12 mm). Using a cable outside this range compromises the IP68 seal and mechanical strain relief.
Q: What is the structural difference between AISI 304 and AISI 316 stainless steel?
A: AISI 304 provides reliable corrosion resistance for standard industrial environments. AISI 316 contains molybdenum, offering superior resistance against chlorides, marine atmospheres, and acidic chemical exposure.
Q: Are locknuts and sealing washers included as standard?
A: Locknuts and O-rings can be supplied as paired sets or bulk-packed according to your purchasing preference. Please specify inclusion when submitting an RFQ.
Q: What is the Minimum Order Quantity (MOQ) for custom threads?
A: Standard catalog stock items have no strict MOQ. Custom machined threads or non-standard dimensions typically require an MOQ starting at 500 pieces per size.
Q: What is the standard production lead time?
A: Standard stock items ship within 3 to 5 business days. Custom production orders require 15 to 25 business days depending on volume and specification complexity.
