ABB 3HAC056707-001 IRB 1200 Tubular Cable Housing Cover Gasket

Tubular Cable Housing Cover Gasket for ABB IRB 1200 Robots

Specifications

Industrial Applications

• Food and beverage production lines running IRB 1200 robots with food grade lubrication, where the wrist joint has to withstand regular wash-down.
• Clean-room and pharmaceutical filling and handling cells where particle ingress at the wrist is a contamination risk.
• Foundry, die-casting and other dust-heavy environments where abrasive dust would otherwise reach the manipulator cable harness.
• Wet or coolant-exposed machine-tending and deburring cells specified with protection class IP67.
• Hygienic pick-and-place and packaging cells — the same position on a Hygienic robot takes the alternate article, so the application is identical but the part number is not.
• Preventive wrist service: fitted whenever the tubular cover or the tubular cable housing is renewed, and worth holding as a shelf spare because it is cheap relative to the cable harness it protects.

Design Purpose

The tubular cable housing is the channel that carries the manipulator cable harness from the upper arm into the wrist. Reaching the wrist on a compact robot means the harness has to pass a joint that moves constantly, so ABB builds that passage as a set of replaceable tubular parts — a tubular with sleeve, a tubular cover, a tubular cable housing, and a cover that closes the housing. Every one of those interfaces is a potential entry point for whatever the robot works in. The gasket sits in the joint between the tubular cable housing and its cover, and its job is simple and non-negotiable: if it fails, the protection class of the whole wrist is only as good as that joint, and the first thing downstream of it is the cable harness — usually the most expensive part in the assembly.

What turns this into a specific ABB article number rather than a commodity O-ring is that ABB builds the IRB 1200 in several protection variants — Standard (IP40), IP67, Foundry Plus, Clean Room, food grade lubrication, and Hygienic — and the sealing parts are not the same across them. In the ABB spare-parts list this gasket is entered for IP67, Foundry Plus, Clean Room and food grade lubrication and is absent from the Standard (IP40) column, which is the list's way of saying the joint is only sealed on the higher-specification machines. On top of that, ABB gives two separate numbers for the same cover joint: 3HAC056707-001 for non-Hygienic robots and 3HAC080701-001 for Hygienic robots. The part number is therefore decided by the robot's protection type, not by the robot model name — and because a gasket is a low-cost item protecting a high-cost harness, ABB specifies it as a replace-if-damaged consumable rather than something to be reused.

Common Failure Modes

• Water, wash-down liquid or coolant ingress into the tubular cable housing, showing up later as corrosion or insulation faults on the cable harness inside.
• Abrasive dust reaching the harness on Foundry Plus machines and chafing the cable insulation.
• Process product or cleaning fluid trapped in the cover joint on food grade and Clean Room machines — a hygiene failure even while the robot still runs.
• Gasket hardened, flattened or cracked with age, so the cover no longer compresses it and the joint stops sealing.
• Gasket cut or pinched during an earlier cover refit, leaking from the first wash-down.
• A reused gasket that has taken a permanent set and cannot re-seal the joint.
• Missing gasket — the cover refitted without it after an earlier repair, leaving the joint open.
• Wrong article fitted — the Hygienic number used on a non-Hygienic robot or the reverse, or an earlier-revision number ordered from an out-of-date manual.
• Cover fasteners loosening under vibration because the gasket no longer provides the intended preload at the joint.

ABB does not publish an alarm code for a failed gasket — ingress damage normally shows up later as a harness or axis-related fault. Please contact us with the fault code displayed on your controller for accurate diagnosis.

Why Choose Us

• Specialized in industrial robot spare parts for ABB, FANUC, KUKA and YASKAWA.
• We separate the two numbers at this position for you: 3HAC056707-001 for non-Hygienic robots and 3HAC080701-001 for Hygienic robots. Tell us the protection type from the robot's type label and we confirm which one your machine takes.
• We quote the tubular section as a group, so the cover, the cover gaskets and the radial and variseal sealings for the same repair can be supplied together.
• We check the article number against your manual revision, because ABB itself warns that the numbers printed in the manual can be out of date.
• Sealing parts are packed so the sealing profile cannot be crushed or distorted in transit, with secure industrial packaging and full order tracking from Shanghai.
• Quote-based service — send your inquiry with the robot model, serial number, protection type and manual revision for a matched offer.
