Slide rails and wear strips sit in machines where material has to be moved forward, turned or held in place while it is moving. That can be pallet tracks, lifting tools, conveyors or machine guides. The surface takes constant abrasion, and the wrong material wears out fast.
Plastic is a good choice because many engineering plastics have both low friction and high wear resistance. They do not rust, they need no lubrication, and they can be made into profiles or sheets that are then cut to size.
Suitable materials
PE-1000
PE-1000 is the first choice when wear resistance matters most. The material has extremely low friction and takes repeated mechanical load for a long time. It is used for rails in conveyors, pallet tracks and other large surfaces where goods rub.
POM-C
POM-C suits cases where precision and stiffness matter more than maximum wear resistance. It can be machined into exact profiles and holds its shape over time. Used for smaller rails, linear guides and parts with tight tolerances.
PA6
PA6 is a stronger and tougher option that takes impact and higher load. It suits rails that carry heavy goods or are exposed to knocks and vibration. Oil filled PA6 also gives lower friction on dry sliding surfaces.
Material comparison
| Material | Best for | Limitation |
|---|---|---|
| PE-1000 | Large surfaces and heavy wear | Less stiff than POM-C and PA6 |
| POM-C | Precision and tight tolerances | Lower wear resistance than PE-1000 |
| PA6 | Heavy loads and impact | Takes up moisture, can swell |
Design and installation
Slide rails can be made as whole sheets, as profiles or as recessed strips. PE-1000 is usually the economical choice for large surfaces because it can be welded and thermoformed into simpler shapes. For more complex profiles the material is milled or sawn to size.
When fitting, do not clamp the plastic harder than necessary. The material moves more than metal when the temperature swings, so the rail needs room to expand. Screw holes should be slotted or larger than the screw so the plastic is not put under stress.
Typical applications
- Pallet tracks and conveyor lines in warehousing and logistics
- Guide rails and wear strips in process industry
- Lifting and handling equipment
- Feed tracks in packaging machines
- Sliding doors and covers on large machines
Maintenance and service life
One of the biggest advantages of plastic rails is that they need little maintenance compared with metal. No grease or oil is needed to keep friction down, which makes them suitable in environments where dirt and dust would otherwise stick. Service life depends on pressure, speed and surface quality, but in many cases PE-1000 beats both steel and aluminum in dry, dirty environments.
When wear finally shows, the rail is usually easy to replace. Since the material can be bought as sheets and rods, a new rail can be cut to size and drilled without special tools. For really large surfaces PE-1000 can also be welded or joined to cover the whole track.
Advantages of plastic compared with metal
- Longer service life in dry, dirty environments
- Lower friction without lubrication
- Lower weight, which makes fitting easier and cuts energy use
- Does not rust and withstands many chemicals
- Can be welded or mechanically fastened as needed
How to choose the right material
For large, smooth surfaces with heavy wear, PE-1000 is hard to beat. For precision parts and smaller profiles, POM-C is a good choice. For heavy loads and impact, PA6 is the better fit. Think about the temperature too, and whether there are chemicals around.
