Multi-Hole Robot Cable Rubber Gland

Mixed Multi-Hole Separated Wiring Design Equipped with holes of varying diameters to sort power cables, signal wires and pneumatic tubes independently. Prevents wire tangling, friction and abrasion during frequent robotic arm rotation, organizing internal wiring of robot pipeline packages cleanly.

Premium EPDM Raw Material, Outstanding Weather & Ozone Resistance Made of industrial-grade EPDM rubber, excels at anti-ozone, anti-UV, anti-aging and waterproof performance. Stable elasticity within -40℃ ~ 120℃, no hardening, cracking or deformation under long-term workshop & open-air working environments, far more durable than ordinary NBR rubber for robot outdoor equipment.

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

Double Outer Annular Grooves, Anti-Slip Locking Installation Two circular positioning grooves on the outer cylinder, perfectly clamped by robot pipeline plastic/metal housings. Stays tightly fixed without sliding or falling off during high-frequency reciprocating robot movements, cutting down 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, collaborative robots, welding & palletizing robot pipeline wiring sealing; small trial orders and large bulk wholesale are both supported.

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

The high-elastic EPDM rubber fits tightly around each cable after installation, forming individual sealed barriers for all wires. It effectively blocks workshop metal filings, coolant, dust, moisture and ozone, avoiding wiring harness abrasion, corrosion and circuit short-circuit faults caused by long-term robotic movement.

High-Performance EPDM Ethylene Propylene Diene Rubber EPDM rubber delivers superior ozone resistance, UV resistance, water resistance and heat resistance compared to nitrile rubber. It maintains stable soft elasticity across -40℃ to 120℃, resisting aging even under strong light, high temperature and humid factory conditions, with a much longer service life for automation equipment exposed to harsh environments.

Mixed Large & Small Aperture Layout Combined big and small hole sizes match standard robot power cables, thin sensor signal lines and pneumatic tubes in one single bushing. Eliminates wire entanglement and mutual friction during multi-angle robot rotation, greatly extending wiring harness service life.

Double Locking Groove Outer Cylinder Two circular positioning grooves on the outer wall enable tight clamping by robot pipeline metal/plastic shells. No displacement or detachment during high-speed robotic arm swing, delivering 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 along with pipeline movement without cracking, adapting to high-frequency dynamic working conditions in automated workshops.
