Connecting Plate for Ø28 mm Tube and Aluminium T-Slot Profile – Leanpipe System Adapter

The connecting plate for an Ø28 mm tube and an aluminium T-slot profile is a practical adapter designed to connect two different structural systems: a modular system of 28 mm round aluminium tubes and structural aluminium profiles with a T-slot. It allows hybrid frames to be built in which a lightweight tube structure works together with a rigid and highly configurable profile structure.

The connector is particularly useful for constructing flow racks, roller tracks and roller conveyors, transport trolleys, assembly workstations and material-flow systems. It allows the end of a round Ø28 mm tube to be attached to a structural T-slot profile, integrating the Leanpipe tube system with a main frame made from aluminium profiles.

This solution is suitable for projects in which part of the structure is made from T-slot profiles, while auxiliary components, guides, supports or frames for roller tracks are made from round Ø28 mm aluminium profiles. This allows the profile type to be matched to the function of each section of the structure.

The adapter can be used with both a silver Ø28 mm round aluminium profile and a black Ø28 mm round aluminium profile. This makes it possible to match the appearance of the structure to the remaining components of the workstation, rack or trolley.

To fasten the plate to the tube, an M8 thread must be tapped in the central hole located in the end face of the round aluminium profile. The tapping service can be ordered together with the Ø28 mm tube. When configuring the profile on the product page, select the 1× M8 tapping option for the end of the tube to which the plate will be attached.

Connecting the Ø28 mm Tube System to a T-Slot Profile

The 28 mm tube-to-T-slot profile connector acts as a transition between a round tube profile and a structural aluminium profile with a slot. It allows the end of the tube system to be mounted directly to the profile frame and enables structures combining the advantages of both systems to be created.

The T-slot profile system provides extensive options for expansion, adjustment and mounting additional accessories. Round Ø28 mm profiles are well suited to lightweight frames, guides, supports and structures used with transport rollers. The adapter makes it possible to combine these systems in one structure without creating a welded connection.

The plate can be used for:

• connecting the end of an Ø28 mm tube to the side of a T-slot profile,
• mounting a tube frame to a structural aluminium profile,
• connecting a roller track to a workstation frame,
• creating a support for a flow rack or FIFO structure,
• creating a transition between the Leanpipe system and a structural profile.

Adapter for Roller Tracks and Material-Flow Systems

The product is designed for structures in which the Ø28 mm tube system works together with T-slot profiles. This type of connection is particularly useful when mounting roller tracks, roller conveyors and flow racks to stable frames made from structural aluminium profiles.

In production and warehouse systems, roller tracks can be used to move bins, boxes, components and materials by gravity between successive stages of a process. The adapter allows the tube structure to be attached to a T-slot frame and creates a modular solution adapted to the organisation of the workstation.

The connector is suitable for:

• Lean Manufacturing and Lean Workplace systems,
• intralogistics and internal transport,
• material-flow and material-feeding systems,
• FIFO racks and flow racks,
• order picking and order preparation,
• supplying assembly workstations,
• organising components next to production lines.

Tapping the Ø28 mm Aluminium Tube

To attach the plate to the Ø28 mm round aluminium profile, an M8 thread must be tapped in the central hole in the end face of the tube. The plate is then fastened directly to the prepared thread using one M8 countersunk screw.

Recommended mounting component for connecting the plate to the tube:

• 1× ISO 10642-M8x20

The tapping option can be selected directly when ordering the silver Ø28 mm round profile or the black Ø28 mm round profile. The product configurator allows the left and right ends of the profile to be machined separately.

Select the 1× M8 tapping option for the end of the tube to which the plate will be attached. If the adapter is mounted on only one side of the tube, the other end does not need to be tapped.

Mounting the Connector to Series 30, 40 and 45 Profiles

The plate has two mounting points for a structural aluminium profile. The screw length must be matched to the geometry of the selected profile series. In addition to the screws, two compatible M6 T-slot nuts intended for the selected series must be used.

Mounting to Series 30 Aluminium Profiles

To attach the plate to Series 30 aluminium profiles, use:

• 2× ISO 10642-M6x12
• 2× 8-4-M6.30

Mounting to Series 40 Aluminium Profiles

To attach the plate to Series 40 aluminium profiles, use:

• 2× ISO 10642-M6x16
• 2× 8-4-M6.40

Mounting to Series 45 Aluminium Profiles

To attach the plate to Series 45 aluminium profiles, use:

• 2× ISO 10642-M6x16
• 2× 10-4-M6.45

The T-slot nuts used with Series 30, 40 and 45 profiles have different geometries. They must therefore be matched to the specific series and slot width and should not be used interchangeably without first checking compatibility.

Installing the Connecting Plate for an Ø28 mm Tube

The adapter is designed to attach the end of an Ø28 mm round aluminium profile to a structural T-slot profile. Before installation, prepare an M8 thread in the end face of the tube and select mounting components suitable for the T-slot profile series.

1. Prepare the round profile: check the tube diameter, cut quality and the condition of its end face and edges.

2. Tap the M8 thread: tap the central hole in the end face of the tube or order the profile with the 1× M8 tapping service for the correct end.

3. Fasten the plate to the tube: position the adapter on the end face of the Ø28 mm profile and secure it using 1× ISO 10642-M8x20.

4. Set the position on the T-slot profile: place the tube with the mounted plate where it will be connected to the main frame.

5. Place the T-slot nuts in the slot: insert two compatible M6 T-slot nuts into the slot of the selected structural profile.

6. Select the screws for the profile series: use 2× ISO 10642-M6x12 for Series 30 or 2× ISO 10642-M6x16 for Series 40 or 45.

7. Pre-tighten the connection: leave enough adjustment range to correct the height, angle and position of the tube in relation to the structure.

8. Check the alignment: verify the level, the relative position of the components and the dimensions of the complete structure.

9. Tighten the connection: after obtaining the correct alignment, evenly tighten the M8 screw securing the tube and both M6 screws securing the plate to the profile.

10. Check stability: before use, ensure that the tube, plate and T-slot profile do not move in relation to one another.

The modular mounting method makes it easy to change the tube position later, extend the workstation or rebuild the complete structure. When modifying the arrangement, the components can be unscrewed and reused elsewhere.
