This multi-hole robot rubber wire bushing is made from high-performance EPDM ethylene propylene diene rubber and features mixed multi-diameter holes. It neatly separates and secures robot cables while providing weather and ozone resistance, waterproof and dustproof protection, and shock absorption. OEM size customization is available, making it a suitable sealing solution for industrial robot arm wiring harness pipeline packages.

Mixed Multi-Hole Separated Wiring Design: Equipped with holes of varying diameters to route power cables, signal wires, and pneumatic tubes independently. Helps prevent wire tangling, friction, and abrasion during frequent robotic arm rotation, keeping internal robot pipeline wiring organized and clean.

Premium EPDM Raw Material for Excellent Weather & Ozone Resistance: Made with industrial-grade EPDM rubber, offering outstanding performance against ozone, UV radiation, aging, and water ingress. Maintains stable elasticity from -40℃ to 120℃ without hardening, cracking, or deformation in long-term workshop and outdoor working conditions. Provides significantly greater durability than standard NBR rubber for robot outdoor equipment.

One-Piece Integrated Molding for High Tear & Compression Resistance: Seamless integral injection molding design with strong tensile and tear strength. Withstands repeated bending and twisting of robot pipelines for millions of cycles without fracture, making it suitable for 24-hour continuous automated production lines.

Double Outer Annular Grooves for Anti-Slip Locking Installation: Two circular positioning grooves on the outer cylinder ensure a secure fit with robot pipeline plastic/metal housings. Remains tightly fixed without sliding or detaching during high-frequency reciprocating robot motion, helping reduce equipment maintenance costs.

Full OEM Customization & Broad Industrial Compatibility: Customizable hole quantity, aperture, overall dimensions, rubber hardness, and logo printing. Compatible with six-axis industrial robots and collaborative robots, supporting sealing for welding and palletizing robot pipeline wiring. Supports both small trial orders and large-volume wholesale supply.

Our multi-hole EPDM robot cable rubber gland is a specialized sealing grommet designed specifically for industrial robot arm pipeline cable packages. The top flat surface features multiple round holes in different sizes, enabling simultaneous routing of multiple power lines, sensor signal wires, and pneumatic hoses for classified wiring arrangement.

After installation, the highly elastic EPDM rubber forms a tight fit around each cable, creating individual sealed barriers for all wires. It effectively blocks workshop metal filings, coolant, dust, moisture, and ozone, helping prevent abrasion, corrosion, and circuit short-circuit faults caused by long-term robotic movement.

High-Performance EPDM (Ethylene Propylene Diene Monomer) Rubber: EPDM provides superior ozone resistance, UV resistance, water resistance, and heat resistance compared with nitrile rubber. It maintains stable soft elasticity from -40℃ to 120℃ and resists aging even under strong light, high-temperature, and humid factory conditions, delivering a significantly longer service life for automation equipment used in harsh environments.

Mixed Large & Small Aperture Layout: A combined arrangement of large and small hole sizes supports standard robot power cables, thin sensor signal lines, and pneumatic tubes within a single bushing. Helps eliminate wire entanglement and mutual friction during multi-angle robot rotation, greatly extending the service life of the wiring harness.

Double Locking Groove Outer Cylinder: Two circular positioning grooves on the outer wall enable tight clamping by robot pipeline metal/plastic shells. Prevents displacement or detachment during rapid robot arm swinging, ensuring consistent long-term sealing performance.

Integrated Injection Molding Craft: Single-piece molding without splicing gaps, with excellent compression and tear resistance. Can repeatedly bend and twist together with pipeline movement without cracking, adapting to high-frequency dynamic working conditions in automated workshops.
