Description
Technical Overview
This injection-moulded mounting component functions as a structural wheel housing. Specifically, engineers designed this hardware for direct integration with 40 Series T-Slot aluminium extrusion profiles. The unit accommodates 7-inch wheels. Consequently, the assembly establishes a secure, stable rotational connection within moving framework assemblies. To provide high structural integrity, the manufacturer constructs this wheel house from PA66+GF30 glass-filled nylon. At the same time, this composite material maintains a low overall component mass.
In addition to wheel mounting, the design incorporates a built-in cable mount. This configuration enables operators to guide and secure a mechanical brake line directly along the housing profile. During system assembly, technicians install the hardware directly onto the extrusion tracks. To do this, they use the included M8 cap head bolts and a nylon lock nut. Therefore, this integrated layout optimises wheel tracking alignment. Furthermore, it simplifies cable management without requiring secondary machining modifications.
Applications
Technicians regularly deploy these 7-inch wheel houses at the structural mobility intersections of modular systems. In particular, assembly teams utilise these robust mounting components to secure wheels on material handling trolleys and transport carts. Furthermore, operators install the housings on automated mobile systems and industrial machinery setups. As a result, the hardware enhances equipment mobility and improves overall structural stability.
The PA66+GF30 glass-filled nylon structure inherently resists operational vibrations and environmental wear. Because of this durability, the wheel house provides an effective solution for custom engineering applications and DIY framework repair projects. Meanwhile, builders must note that the mounting interface matches 40 Series family constraints exactly. The alignment attributes also adhere strictly to these dimensions. As a direct consequence of these unalterable boundary constraints, this hardware configuration does not interface with smaller 20 Series extrusion framing layouts.

Maker Store Tips and Tricks
-
Engage the four included T-slot alignment tabs completely into the profile track channels to ensure perfect parallel alignment before torquing down the mounting fasteners.
-
Route the brake line cleanly through the built-in cable mount prior to completing the wheel assembly to preserve a tidy workspace and clear physical boundaries.
-
Ensure the M8 nylon lock nut is completely engaged on the threads of the 50mm cap head bolt to prevent components from loosening due to operational vibrations.

What makes T-Slots such an easy assembly task?
Building frames out of T-Slot extrusions is easy because they eliminate the need for specialised tools or welding, simplifying the assembly process. Building frames using T-Slot Linear Rail will require;
- 40 Series T-Slot Extrusions: These are the main structural components, usually made of aluminium, with slots along their lengths that allow you to easily connect various parts and accessories.
- 40 Series Brackets and Connectors: These are specialised components designed to fit into the T-Slot extrusions and secure them together at various angles. They include corner brackets, T-nuts, L-shaped brackets, and other connectors.
- Fasteners: Bolts, screws, and nuts are required to attach the brackets and connectors to the T-Slot extrusions securely.
- Tools: Basic hand tools like wrenches, Allen keys (hex keys), and screwdrivers are necessary for assembly. Additionally, a saw may be needed to cut the T-Slot extrusions to your desired lengths.
