Manufacturer direct selling polymer idle

  Polymer belt idler is a new generation of revolutionary idler patented product developed by our company, patent No
: zl2017 20404702
5; The product structure includes five parts: roller skin, bearing, shaft, bearing seat and seal
Through the close cooperation of the bearing seat and relevant seals, the product strictly isolates the contact between the bearing and the outside world to avoid pollution
After testing, the water can not be poured in, which absolutely ensures that the bearing works in a good working environment and fully guarantees its service life

1
  Long life
Under the same working conditions, the service life of steel idler is more than 5 times

2
  Excellent cost performance
The price is slightly higher than that of the steel idler, which can save more than 50% of the use cost for the user within its normal service life
This does not include other significant benefits brought by improving the service life of the belt, saving energy consumption and reducing labor intensity

3
  Protective belt
1
  Special labyrinth seal design (water can not be poured in after testing), which can effectively protect  
The long-term and continuous operation of the bearing can avoid the dry grinding of the belt and the roller skin caused by the frequent non rotation of the steel idler and ceramic idler bearings, and greatly improve the service life of the belt

2
  The roller skin is made of ultra-high polymer material, with extremely low surface friction coefficient and self-lubricating, which is beneficial  
It can protect the belt and prolong its service life

3
  The roll surface is smooth and non-magnetic, and it is not easy to absorb iron powder, dust and various viscous substances;
The defects of steel idlers and ceramic idlers are greatly avoided, so as to prolong the service life of the belt

Steel idlers and ceramic idlers are seriously attached with photos
4
  After long-term use, even if the roller skin is worn and leaked, the belt will not be damaged, which greatly avoids the steel idler
In particular, the defects of ceramic idlers (fragile) and the resulting damage to the belt, thus extending the service life of the belt


4
  Energy saving and easy replacement

  Light weight, only one-half of the steel idler and one-third of the ceramic idler, which is extremely easy to replace and has obvious power saving effect

5
  Safe use and environmental protection
1
  The noise is only half of that of steel idlers, effectively eliminating noise pollution and improving the working environment

2
  Resistant to acid, alkali, salt and other chemical corrosive media

3
  It can work between -269 ℃ and +80 ℃ for a long time

Polymer idler
The roll cover is made of 300 molecular weight ultra-high molecular weight polyethylene pipe, which has the advantages of long wear life, no adsorption of iron powder, low friction coefficient with the belt, and can greatly extend the service life of the belt
