Steel rollers are highly versatile when it comes to their various uses. The suitability of which a roller is to be used in a particular condition is highly determined by the efficiency of the sealing elements and their bearings. The load ability of a roller is mostly dependent on its bearing and its shaft’s diameter. There are different kinds of rollers which have different surface finishes, such as, garlands and return rollers, carry, greased for life and impact rollers. There are many models of rollers, they are;
HR100STEEL ROLLERS-GST/TS/TSE (formerly known as HM100 rollers) – These are usable with every belt width, all duties and every application. Depending on the need, these are delivered with different end fittings and tube thicknesses. They also come with bearing holders that have been machined with very solid bearing holders. Its roller diameter is 51-219mm, the shaft diameter is 17-40mm and its roller diameter is 100-3000mm.
HR100 Rollers (Formerly HA120/HV120) – HA 100 series ranges from 102mm (4”) – 194 (7 5/8”) and has bearing sizes that range in between 6201 – 6310 to meet market requirements. The HA120 and HA130 steel rollers are used for handling bulk material applications; this is because they are rollers with low noise due to improved dynamic balancing and a reduced level of vibration. Its roller diameter is 102 – 178mm, while its shaft diameter is 22 – 56 mm.
HM140 END – FORMED STEEL ROLLER (Formerly HV140 rollers) – This is an environmentally friendly roller. It requires low power which means that, it emits less CO2. It also has less noise. Its highly accurate and quality assembled machine is made in such a way that, bearing misalignment is effectively brought down. It exceeds the standards of CEMA D, E AND F. It is also produced as return rollers, garlands and also carry- rollers. Its roller diameter is 102 -220 mm in diameter, while the shaft diameter is 42 – 62mm, and the roller length 250 – 2500mm.
HM150 FORMED STEEL ROLLER – On top of the HM140 series, the HM150 series come with a roller shell that is flow formed. This ensures the shell is exceptionally round and very hard. The increased wall thickness at the shell’s center gives room for better loading and lowers the shell’s deformation. These rollers do not require balancing due to the TIR which is very low and the thickness of the shell is also quite constant. This ensures a higher durability level. Its roller diameter is 159, 178, and 194 and 219 mm, its shaft diameter is 40, 50, and 60mm, and its roller length is 380 – 1450mm.
