Good Price Original Robot Ring ABB 3HAC7343-1 Spare Part Accessory for Industrial Machinery

The ABB Robot Ring 3HAC7343-1 is a genuine ABB mechanical component designed for use in the linkage and sealing areas of ABB industrial robots, particularly within the IRB 660 series palletizing robot family. As a critical ring element in the robot arm’s linkage system, it helps maintain precise alignment, smooth motion, and long-term mechanical stability in demanding industrial environments.

This ring is manufactured to ABB’s strict dimensional and quality standards, ensuring it fits perfectly in the designated assemblies and works seamlessly with associated components such as support washers, bearings, and link rods.

Technical Overview of ABB 3HAC7343-1

Role of 3HAC7343-1 in ABB Robot Mechanics

In the IRB 660 palletizing robot, the 3HAC7343-1 ring appears in the spare-parts documentation as part of the linkage system between the upper and lower rods, and also in assemblies where sealing and alignment are required.

Its main functions include:

• Providing a precise seating surface between moving linkage elements

• Helping to maintain alignment of the rods and bearings under dynamic load

• Supporting the sealing and protection of lubricated joints in certain assemblies

• Contributing to the overall stiffness and repeatability of the robot arm

Because the linkage system constantly transfers motion and torque between axes, small components like the 3HAC7343-1 ring have a direct impact on the robot’s positioning accuracy and long-term reliability.

Key Features and Benefits

1. Genuine ABB geometry and fit
The 3HAC7343-1 is designed specifically for ABB robot arm linkages. The dimensions and tolerances are matched to the IRB 660 mechanical design and associated parts such as support washers (3HAC7253-1) and needle bearings (3HAC3311-4), which are listed together in the official spare-parts breakdown.

This precise compatibility means:

• No modification or machining is required during replacement

• Correct preload and contact surfaces are maintained

• Reduced risk of misalignment or uneven wear

2. Stable support for bearings and washers
In the linkage section, the 3HAC7343-1 ring works in combination with support washers and bearings to create a stable, low-friction joint. This is particularly important for high-speed palletizing robots like the IRB 660, where repeated acceleration and deceleration generate significant mechanical stress.

3. Compact but robust construction
With an approximate weight of 0.12 kg and compact outer dimensions around 80 × 80 × 15 mm, the ring is optimized for strength while keeping the moving mass of the arm as low as possible. A low moving mass helps the robot maintain high throughput and reduces load on the drive system.

4. Designed for harsh industrial environments
ABB robots are widely used in applications such as palletizing, material handling, packaging, and logistics. In these environments, components must withstand vibration, dust, temperature variations, and continuous duty cycles. The 3HAC7343-1 ring is engineered as part of this robust mechanical ecosystem, supporting long service life when used with proper lubrication and maintenance.

Typical Applications

The ABB Robot Ring 3HAC7343-1 is primarily used as a spare or replacement part in:

• ABB IRB 660 palletizing systems – maintaining smooth joint motion in the linkage between arms

• Material handling lines – where robots work continuously with high cycle counts

• Warehouse automation and logistics cells – for palletizing, depalletizing, and stacking operations

• Food & beverage, building materials, and bag palletizing – typical industries for IRB 660 robots, where mechanical reliability is essential

Although the part number is closely associated with IRB 660 documentation, independent distributors often list it more broadly as an ABB “ring” or “robot ring” for ABB robotics, indicating it may also be used in compatible assemblies or variants depending on the robot configuration.

Installation and Maintenance Considerations

When installing or replacing the 3HAC7343-1 ring in an ABB robot, technicians should follow ABB’s official product manual and service instructions for the specific robot model. Typical best practices include:

• Verifying the exact position and quantity of rings required in the linkage assembly

• Inspecting mating components such as link rods, support washers, and bearings for wear or damage

• Cleaning the contact surfaces and removing old debris or hardened lubricant

• Applying the recommended lubricant (for example, ABB references Alvania WR2 grease in related assemblies)

• Using the correct tightening torques and any specified thread-locking compounds where relevant

Careful replacement ensures that the new ring works as intended and that the joint maintains its designed stiffness and smooth motion.

Why Use Genuine ABB 3HAC7343-1 Rings?

Using genuine ABB robot rings rather than generic alternatives offers several advantages:

• Guaranteed compatibility with ABB drawings and part lists

• Consistent material and heat-treatment quality suited to repeated cyclical loads

• Reduced downtime risk because the part fits correctly the first time

• Better traceability for maintenance records, audits, and warranty discussions

Many specialized automation distributors list this part as a new, original ABB spare with factory packing and standard warranty, emphasizing its role as a critical OEM component.

Ordering Information and Stock

The ABB Robot Ring 3HAC7343-1 is available through:

• ABB’s own sales channels and service partners

• Authorized industrial automation distributors and robotics specialists

• Independent automation parts suppliers and online industrial marketplaces

When requesting a quotation or checking stock, it is best to provide:

• Full part number: 3HAC7343-1

• Description: Ring / Robot Ring for ABB robot linkage

• Robot model (for example, IRB 660) and assembly section if known

• Required quantity and any specific delivery requirements

Summary

The ABB Robot Ring 3HAC7343-1 is a small but essential mechanical element in ABB industrial robots, particularly in the linkage and sealing areas of the IRB 660 palletizing robot. Its precise dimensions, robust construction, and integration with ABB’s linkage design help maintain accurate motion, reduce wear on bearings and washers, and extend the service life of the robot arm.

For maintenance teams and spare-parts buyers, choosing genuine ABB 3HAC7343-1 rings is a straightforward way to protect robot performance, minimize unexpected downtime, and keep demanding palletizing and material-handling applications running smoothly.
