Glider Rollers Idlers
Glider rollers, made of UHMW PE, is an INNOVATIVE products, very useful in extreme conditions. Glider,the import substitute is a taken by most of the customer with open hearts to make the conveying more efficiently. Low wear, High Impact Strength and anti sticking properties are being exploited fully to effectively use the UHMW PE Rollers. The life of UHMW PE Glider Roller is very high as compare to Metal or any other plastic Roller.
UHMW PE (Ultra-High Molecular Weight Polyethylene) idlers, rollers, and return rollers are widely used in various industries, particularly in material handling and conveyor systems. Here’s an overview of their usage, benefits, and applications:
1. Conveyor Systems:
- Carrying idlers: Support the loaded belt.
- Return rollers: Guide the empty belt back to the loading point.
- Impact rollers: Absorb shock at loading points.
2. Material Handling:
- Guide rollers in chutes and transfer points.
- Rollers in sortation systems.
3. Mining and Quarrying:
- Conveyor rollers for transporting ore, coal, and aggregates.
4. Agriculture:
- Rollers in grain handling equipment.
- Guide rollers in fertilizer spreaders.
5. Food Processing:
- Conveyor rollers in food-grade applications.

| Belt Life | Low | High | Low Running Cost |
| Abrasion Resistance | Low | High | Increased Life |
| Adhesive | Yes | No Adhesive | Low Maintenance, Less Down Time |
| Corrosion Resistance | Low | High | Low Maintenance, Less Down Time |
| Co-efficient of Friction | High | Low | Increased Life |
| Wall Thickness | Low – 3 MM | High – 7/13 MM | High Life |
| Sharp Edges | Formed | No Formation | Saves Belt from Damage |
| Modular | No | Yes | Can Change Bearing if required |

| Impact Strength | High | High | Highest Impact Strength among all plastic, No Breakage |
| Water Absorption | Zero | Zero | Better than any other Plastic |
| Over All Life | Low | Very High | Very Low Wear gives |
| Over All Maintenance | High | Low | Less Down Time, Low Maintenance |
| Noise | High | Very Low | Silent Work Environment |
Benefits of UHMW PE idlers, rollers, and return rollers:
1. Low Friction:
- Reduces power consumption.
- Minimizes belt wear.
2. Noise Reduction:
- Quieter operation compared to steel rollers.
3. Lightweight:
- Easier installation and maintenance.
- Reduces stress on support structures.
4. Corrosion Resistance:
- Ideal for wet or corrosive environments.
5. Abrasion Resistance:
- Long service life in abrasive material handling.
6. Non-Stick Properties:
- Reduces material buildup and carryback.
7. Impact Resistance:
- Withstands shock loads at transfer points.
8. Temperature Resistance:
- Performs well in a wide range of temperatures.
9. Chemical Resistance:
- Suitable for handling various chemicals and materials.
10. Low Maintenance:
- Reduced need for lubrication and replacement.
Specific Applications:
1. Troughing Idlers:
- UHMW PE rollers arranged to form a trough shape, supporting the loaded belt.
2. Flat Return Idlers:
- Single UHMW PE roller supporting the return belt.
3. V-Return Idlers:
- Two angled UHMW PE rollers forming a V-shape to center the return belt.
4. Impact Beds:
- Multiple UHMW PE rollers arranged to absorb impact at loading zones.
5. Self-Cleaning Spiral Rollers:
- Specially designed UHMW PE rollers with spiral grooves to prevent material buildup.
Considerations for Implementation:
- Proper sizing based on load and belt speed.
- Appropriate spacing of idlers along the conveyor.
- Regular inspection for wear and alignment.
- Potential for static buildup in some applications (may require antistatic additives).
- Temperature limitations compared to steel rollers (though still suitable for most applications).
UHMW PE idlers, rollers, and return rollers offer significant advantages in terms of reduced maintenance, energy efficiency, and extended belt life. They are particularly valuable in applications involving abrasive materials, corrosive environments, or where noise reduction is important.
