Heavy-Duty HDPE Roller

Megaroller HDPE Rollers are an innovation in reinforced high-density polyethylene (HDPE)
conveyor rollers. Utilizing Megaroller’s unique design and incorporating our patented Sealing
Arrangement, Bearing and Seal Housing, and Roller Shell, Megaroller HDPE Rollers are a
robust, long-lasting and ecologically-sound alternative to conventional steel rollers. All plastic
components have been designed in-house and is produced in our factory.

Our HDPE rollers are recognised as the market’s most esteemed roller. The Megaroller design results in unprecedented performance and a market-leading lifespan. Some advantages are:

Proven, Patented Technologies:

  • Advanced Sealing Arrangement (Patent number 99/5238) Megaroller’s patented Sealing Arrangement, consisting of a back seal, a shock-resisting bearing cover, an outer seal, and four low-friction contact lip seals are proven by the SABS as the most effective sealing arrangement available on the market. This unique sealing arrangement is non-corrosive, has a very low friction coefficient, and is highly resistant to chemicals, acid, water and wear.
  • Durable Roller Shell (Patent number 2001/6394) Our patented Roller Shell’s wall thickness ranges between 13mm to 19mm (depending on diameter) and a reinforced HDPE drum with a castellated internal transverse cross-section. Four times thicker than the wall thickness required by the SABS 1313, Megaroller ensures a longer shell life, while about 60% of the weight of conventional steel rollers.
  • High-impact Bearing and Seal Housing (Patent number 2001/6883) Megaroller’s patented Bearing and Sealing Housing, injection-moulded from high-impact HDPE to ensure precision, eliminates the risk of misalignment and distortion. Due to its innovative design, the bearing and sealing housing is able to absorb the impact imposed by uneven loads and belt speed. The the patent includes the heat fusion process used to permanently
    attach the bearing housing to the roller shell to form a totally sealed and aligned roller drum which is precision machined to a concentricity (TIR) specification of 0,40mm maximum.

Unprecedented Performance:

The Megaroller HDPE Roller is designed to operate in extreme temperatures, harsh operating conditions, and in highly corrosive, chemical or coastal conditions which are known to attack and destroy conventional steel rollers.

The main body of the roller is made entirely from HDPE which is known for its high resistance to wear by abrasion and sun exposure; fire retardant characteristics; low friction co-efficiency; ability to absorb high impact forces; gripping capabilities, and high melting point.

Utilizing Megaroller’s patented technologies, and with advanced applications to prevent seizing and conveyer roll-backs, Megaroller HDPE Rollers have
proven to outperform similar products. The Megaroller HDPE Roller’s perfectly-concentric design and unique configuration decreases vibration, which
translates into lower repair and maintenance costs. They are lighter in weight than steel rollers, run quieter, and have a longer lifespan.

Lubricated for Life:

Bearing lubrication is an important factor affecting the theoretical lifespan of any conveyor roller. Bearings are lubricated at the factory and placed in a protective housing that is completely sealed by our unique sealing arrangement. This eliminates the need to lubricate at the user level, prevents the risk of over or under lubrication, and mitigates the risk of bearing failure due to lack of lubrication.

Our high-spec lubricant ticks all the boxes:

  • Contains Anti-Rust Additives
  • Contains Anti-Oxidant Additives
  • Excellent Water Repellent Properties
  • Mechanical Stability
  • High-Temperature Performance
  • Operating Temperature from below -30ºc to +200ºc

Available in:

Standard

Megaroller HDPE Rollers have high-resistance to wear by abrasion
and ultra-violet rays. Megaroller’s patented Sealing Arrangement
allows these rollers to be used in the harshest weather conditions
and in moisture-rich environments.

Anti-Seize

The roller utilizes Megaroller’s innovative Anti-Seize Technology,
comprising a side flinger which remains static while the roller is
running. This protects the sealing arrangement against any spillage
that could get lodged between the shaft and the roller’s side face. It is
specifically suggested for dusty environments.

Anti-Runback

Our Anti- Run-Back roller can be applied to incline belts to
prevent the belt from running back in the event of a “belt-snap”.
Rollers are fitted with Megaroller’s patented sealing arrangement
as well as a roller brake system which ensures that the roller can
only run in one direction.
