Product Description
UHMWPE conveyor rollers,HDPE rollers, Belt conveyor rollers
Advantages and benefits:
1, Lower weight- 50% lighter than steel roller which means lower power consumption , Easier to install and maintenance, Easier /cheaper transportation.
2, Adequate load capacity- Ultra thick abrasion and corrosion resistant -10-15mm thick UHMWPE shell can guarantee very good performances of roller which means longer life of roller and lower maintenance.
3, Lower abrasion and corrosion of UHMWPE shell has high resistance to chemical agents which means the roller will not rust and is suitable for a wide variety of applications.
4, Belt friendly since UHMWPE shell will not wear and cut the belt.UHMWPE shell contains carbon black increasing ultra violet resistance.
5, Outer protective stone guard with integral labyrinth design minimizes possibility of being jammed by spilt material and provides additional protection from water and dust.
6, Multi part labyrinth seal protects the bearing from ingress of contaminants.
7, Machined finish ensures very low run-out (TIR≤0.05mm), minimizing vibration and noise emission.
8, Self -cleaning UHMWPE roller surface which means prevention of build up of material which main cause of belt mis-tracking and less spillage from the belt.
9, Ultra low running resistance sealing system and break away mass which reduces power and energy consumption for start up and continuous operation.
Typical applicatios:
Mining—coal, iron ore,gold, diamonds,platinum,copper,uranium,Coal process plants,Coal fired power stations,Import/export terminals,Steel plants,Fertilizer plants,Cement plants,Gravel plants,Quarry.

Can V pulleys withstand variations in environmental conditions?
V pulleys are designed to withstand variations in environmental conditions to a certain extent. However, their ability to withstand different environmental factors depends on several factors, including the materials used, the specific design of the pulley, and the maintenance practices employed. Here is a detailed explanation:
1. Temperature:
V pulleys can generally withstand a wide range of temperatures. The specific temperature limits depend on the materials used for construction. For example:
- Cast iron and steel pulleys can handle high temperatures and are suitable for applications in industrial environments.
- Aluminum pulleys have a lower temperature limit, and excessive heat can affect their structural integrity.
- Plastic pulleys may have temperature limitations, and exposure to high temperatures can cause deformation or melting.
It’s important to consider the temperature range in which the V pulleys will operate and select materials accordingly.
2. Moisture and Corrosion:
V pulleys can be susceptible to corrosion, particularly if they are made of materials like cast iron or steel. Exposure to moisture, humidity, or corrosive substances in the environment can lead to rust or degradation of the pulley components.
To mitigate corrosion risks, protective measures can be taken, such as:
- Using corrosion-resistant materials like stainless steel or aluminum alloy.
- Applying coatings or finishes like zinc plating, powder coating, or anodizing to provide a barrier against moisture and corrosive agents.
- Regular cleaning and maintenance to remove accumulated dirt, debris, or corrosive substances.
3. Dust and Contaminants:
V pulleys may be exposed to dust, dirt, and other contaminants present in the environment. These particles can accumulate in the pulley grooves, affecting the grip and performance of the V-belt.
To minimize the impact of dust and contaminants:
- Implement proper guarding to prevent the ingress of debris and contaminants.
- Regularly clean the pulleys to remove accumulated dirt and ensure smooth belt operation.
- Consider using pulley covers or seals to provide additional protection against contamination.
4. Shock and Vibration:
V pulleys may be subjected to shock loads or vibrations in certain applications. These dynamic forces can affect the overall performance and integrity of the pulley and the power transmission system.
Design considerations, such as proper balancing, robust construction, and secure hub attachment, can help minimize the impact of shock and vibration on the pulleys.
5. UV Exposure:
If V pulleys are used in outdoor applications, they may be exposed to ultraviolet (UV) radiation from sunlight. Prolonged UV exposure can degrade certain materials, particularly plastics, causing them to become brittle or discolored.
If UV exposure is a concern, selecting materials with UV-resistant properties or applying protective coatings can help mitigate the effects of UV radiation.
While V pulleys are designed to withstand variations in environmental conditions, it is essential to consider the specific requirements of the application and select appropriate materials, coatings, and maintenance practices to ensure their long-term performance and durability.
