Ultra High molecular weight polyethylene, or UHMW, as it is commonly known, is a high crystalline high density polyethylene polymer with a median molecular weight that falls within the range of 3.1 to 5.0 million.


Parts machined from UHMW polyethylene showcase an exceptional combination of outstanding properties. High abrasion resistance, low coefficient of friction, self-lubrication, non-adherent surface, excellent chemical fatigue, impact resistance, ease of machinability, and good noise dampening properties, are all inclusive of UHMW. Its outstanding characteristics embrace very high resistance to wear and abrasion, and high performance at extraordinarily low temperatures (i.e. liquid nitrogen -259 degrees C). Only when temperatures reach 185 degrees F, will UHMW start to soften and lose its abrasion resistance characteristics.


Because UHMW features a comparatively high expansion and contraction rate once subjected to temperature changes, it\'s not suggested for close tolerance applications in these environments


However, custom UHMW machining to close fabrication tolerances is easily achieved through Vanderveer Industrial Plastics' CNC machining abilities.

Except for bearing and shaft are made of steel, all other parts of high strength composite material roller are made of thermoplastic engineering plastics such as ultra-high molecular weight polyethylene(UHMWPE)or high-density polyethylene(HDPE). Aluminum-alloy pipe inside makes heavy load mechanical strength.


  • Compared with steel roller, the weight of high strength composite material roller decreases 50% that lowers the start and braking consumption of the conveyor.
  • Low-abrasion and corrosion resistance features makeroller more durable and decrease maintenance cost on site.
  • Low noise benefited by thermoplastic material with shock absorption feature.
  • Plastic surface of pipe with low friction will not wear the belt that can prevent belt from damage.
  • Multi-layer labyrinth seal ring has excellent water and dust proof property, which has low operation resistance.
  • Surface of roller will not accumulate material that can effectively prevent belt from misalignment.

Conveyor Idlers are used to carry or convey conveyor belt loaded with bulk material. These carrying idlers are fabricated from different materials such as heavy guage steel tubing or seamless steel tubing, depending upon the requirement and their applications. These idlers are specially designed to provide smooth transition of bulk material for long period of time and are available with impact rings made of special shock absorbing compound.

Troughing idlers are use for conveying bulk materials, and are designed and manufactured with Troughing angels of 20° and 30° normally. Idlers of 45° trough angle or any other angle are also manufactured as per customer's design and drawings. We can also design manufacture and supply 5 rollers type idlers. Mounting brackets are manufactured out of standard steel sections to have rigidity and stability of the frame. Shafts are manufactured out of Carbon steel bright steel bars suitable for any torsional load and bending movement.

Return Roller is a pivoting track-mounted return idler that allows for safe, quick, and simple one-sided serviceability and roll replacement. The track-mounted design reduces the risk of injury and allows quick replacement of the roll.

Features and Benefits:

Requires minimal rigging and heavy lifting. Sliding track-mounted design reduces risk of injury and allows replacement to be done quickly and easily.

Designed to allow for service from one side of the conveyor.

Fits any belt 24" to 72" wide Three-piece hanger frame adjusts to accommodate different belt widths. Universal bracket fits most major idler manufacturers’ idlers and sizes.

Carry Roller

The Roller are very important component of belt conveyor. They are present along the entire Length of the conveyor, support the belt and moving the materials loaded on the belt. The diameter of the idler could be correctly selected according to the belt width and Travel speed. We produce f60mm, Ǿ 63.5mm, Ǿ 76mm, Ǿ 89mm, Ǿ 102mm, Ǿ 114mm, Ǿ 127mm, Ǿ 139mm, Ǿ159mm. They almost cover all belt width requirement General steel Roller consists of idler shell, spindle, bearing, bearing house, seals Equipment and axial fixed unites.


1) Steady running, reliable quality and reduce maintenance;

2) Less movement longitudinally, rotating smoothly, extends the life span;

3) Various bearing housing and sealing structure are available for the customer's choice;

4) Multipass labyrinthine sealing, preventing the mixed dirt and water immersed;

5) Manufacturing by steel pipe especially for of high precision roller, ensuring the strong load, low shaking and less noise.

For using special positions

Special positions are: sticky_left, sticky_right, notice, tool_bottom. You can use them for any module type. For using this, please go to Module Manager and config your module to your desired position.

You can disable by:

  • Go to Administrator » Template Manager » Your_Template » Tab: Advanced » Use special positions » select: No for all special positions
  • Go to Administrator » Module magager » Your_Module(by postion: sticky_left/stickey_right/notice/tool_bottom) » Status: Unpublish for that module

For customize module in special position

The solution is using Module Class Suffix. You can customize button, module content follow Module Class Suffix

E.g. Module Class Suffix: bg-white @bullhorn then:
- Class of buttom is 'ico-bullhorn'. If without @... the default is 'icon-pushpin'
- Class of module is 'bg-white'
