HIGH SPECIFICATION LUBRICATION

Megaroller 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 user level, prevents the risk of over or under-lubrication, and mitigates bearing failure due to lack of lubrication.

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 is 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.

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 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 0,20mm maximum.

DURABLE ROLLER SHELL (Patent number 2001/6394)

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. Our patented Roller Shell’s wall thickness ranges between 13mm to 19mm (depending on diameter) and features a reinforced HDPE drum with a castellated internal transverse cross section.
