Buy Set Collars from TORWEGGE
For the smooth operation of a wheel with an axle, several factors are crucial: the axle must be securely fixed to the chassis, and the wheel’s rotation must be optimized by ensuring it is neither too tightly nor too loosely attached to the axle. This is where set collars come into play. Here, we explain why set collars are essential and how to use them correctly.
Installing Set Collars on Wheel Axles
Set collars are typically mounted on the axle, one on each side of the wheel, allowing the wheel to rotate freely between them. When using a STARLOCK® end cap, the outer set collar is replaced by the end cap. If rings are used on both the inner and outer sides, an additional plastic end cap should be attached to the wheel hub to protect it from corrosion.
One key advantage of this setup is that set collars can be easily removed and reused whenever needed. The set collars are secured to the axle by tightening a small grub screw, ensuring a firm and reliable hold.
Secure Hold of the Set Collar
To ensure the durability of the construction, industrial standards dictate that the shaft—equivalent to the axle in this case—should be made of a softer material than the threaded pin, here represented by the integrated grub screw. This allows the screw to press into the axle, creating a small indentation on the axle’s surface.
This method significantly enhances stability, especially under high axial loads caused by high rotational speeds or cornering forces. As a common practice, the axle is often pre-drilled slightly at the location of the grub screw before mounting the set collar to achieve the same stabilizing effect.
Features of High-Quality Set Collars
High-quality set collars are essential for ensuring a secure, low-friction, and durable connection between the wheel and the axle. The choice of material plays a crucial role. We offer steel models that are durable, corrosion-resistant, and wear-resistant.
To guarantee a precise fit and optimal functionality, we prioritize meticulous manufacturing, achieving exact dimensions and tight tolerances. This ensures our set collars fit snugly on the axle without excessive friction, effectively withstanding both radial and axial loads for maximum performance.
Grub Screws for Easy Installation
Installing set collars with grub screws is both simple and precise, typically requiring no complex tools. When properly tightened, the grub screw effectively prevents the collar from slipping. Another advantage of this fastening method is that the set collars can be easily removed and reattached as needed, providing flexibility and convenience.
What to Consider When Choosing Set Collars
The most crucial factor is selecting the correct inner diameter to ensure the set collar fits securely on the shaft. Additionally, the ring's width plays a vital role in handling the required loads, so it’s essential to be aware of the specific load requirements.
If the wheels are exposed to dirt, dust, or moisture, using a STARLOCK® end cap is advisable to provide the necessary protection and enhance the durability of the assembly.
The Importance of Set Collars in Industry
Set collars may be small components, but they play a crucial role across countless industrial sectors. In the mechanics of drive systems such as shafts or rolling mills, they are indispensable and have a long history of use. The invention of the recessed threaded pin in the early 20th century marked a significant advancement.
In older industrial systems, the head of the threaded pin often extended beyond the typically massive set collar, posing a risk of snagging on workers' clothing and pulling them into machinery. Modern set collars with grub screws have significantly reduced such risks, ensuring a much safer working environment.
