The fixed roller on the Major sander frame is an essential component of the sander's sanding belt support system. Its main role is to hold the sanding belt in place and guide it during sanding. Here's how it works and when it may be necessary to change this part:
How the fixed roller works :
1. Guiding the sanding belt: The fixed roller is designed to support the sanding belt and keep it in contact with the surface to be sanded. It allows the sanding belt to glide smoothly and evenly over the surface during sanding.
2. Pressure distribution: The fixed roller helps to distribute the pressure exerted on the sanding belt evenly, resulting in uniform sanding and a better quality surface finish.
Fixed roller wear points :
1. Surface wear: The surface of the fixed roller is subject to normal wear due to constant contact with the sanding belt. Over time, this wear can cause the surface of the roller to become uneven, which can affect the quality of the sanding.
2. Physical damage: The fixed roller can be damaged by abrasive particles or foreign objects trapped between the sanding belt and the roller, causing scratches or damage to its surface.
3. Ageing: Depending on the materials of construction and frequency of use, the fixed roller may age and degrade, which may also affect its performance.
When is it necessary to change the part?
It's important to regularly check the condition of the fixed roller on your Major sander for signs of wear or damage. Here are a few indications that suggest it's time to replace this part:
1. Uneven sanding: If you notice that the sander leaves irregular marks or does not obtain a uniform sanding result, this may indicate wear on the fixed roller.
2. Abnormal noises: Friction, squeaking or rattling noises coming from the sander may indicate a problem with the fixed roller.
3. Visible damage: If there are any scratches, cracks or other visible damage to the surface of the fixed roller, it must be replaced.
4. Loss of efficiency: If the quality of sanding decreases significantly despite appropriate adjustments, the fixed roller may be to blame.
In general, it is advisable to follow the specific recommendations of the manufacturer of your Major sander regarding maintenance and replacement of parts. If you notice any signs of problems with the fixed roller, it is best to have it replaced by a qualified Repex Floor professional or to contact the after-sales service for help. Also be sure to follow all safety procedures when servicing or replacing components on your sander.
