Advanced Mining offers the world's widest range of equipment for rock drilling, rock excavation, processing, demolition, bulk-materials handling and equipment for surface and underground mining.
Steel rollers
Sandvik steel rollers are highly versatile. Efficient sealing elements and bearings determine which type is suitable for different conditions. With this selection Sandvik steel rollers meet customer requirements even in the most extreme conditions. Loadability of one roller is very much dependable on bearing and shaft diameter. More specific information concerning loadability is found in attached selection pages. Sandvik steel rollers are available with various surface finishes, produced as carry, impact, return rollers and garlands, greased for life and factory sealed.

We offer two series of steel rollers:
HR100 standard end-cap rollers and HM100 formed rollers, designed especially for mining conveyors and similar applications.
Models
HR100 STEEL ROLLERS - GST/TS/TSE - former HM100 rollers
Available for all belt widths, every application and duties. Can be delivered with various tube thicknesses and end fittings. Equipped with bearing holders machined from solid or with deep drawn bearing holders.
Key specifications
| Roller diameter | 51-219 mm |
| Shaft diameter | 17-40 mm |
| Roller length | 100-3000 mm |
HR100 STEEL ROLLERS - former HA120/HV120
Sandvik HA100 series rollers' diameters range from 102 mm (4") to 194 mm (7 5/8") with bearing sizes from 6204 to 6310 to meet the local market requirements. HA120 series steel rollers for most bulk material handling applications, and HA130 machined and balanced low noise rollers with quiet operation thanks to good dynamic balancing and reduced vibration.
Key specifications
| Roller diameter | 102-178 mm |
| Shaft diameter | 22-56 mm |
With the new HM100 series rollers, an intelligent design and sophisticated manufacturing process gives a more straightforward product – with superior characteristics. Designed for highest loading capacities and belt speeds, formed rollers offer special features such as long life, low weight, energy efficiency, low vibrations and decreased noise levels. Formed rollers are also available with hollow formed shafts instead of full steel shafts. Hollow shafts provide less deformation and lower weights.
Models
HM140 END-FORMED STEEL ROLLER - former HV140 rollers
The HM140 end-roller is environmentally friendly thanks to the lower power requirement compared to a conveyor system with conventional rollers, which leads to decreased CO2 emission. Furthermore, the HM140 end-formed rollers’ reduced noise level brings added value to the working environment. Due to the high accuracy and quality in the production and assembly, initial bearing misalignment in these rollers is effectively diminished. The HM140 end-formed rollers can be supplied to exceed CEMA D, E and F standards and can be produced as carry-, return rollers and garlands.
Key specifications
| Roller diameter | 102-203 mm |
| Shaft diameter | 42-62 mm |
| Roller length | 250-2500 mm |
HM150 FORMED STEEL ROLLER
In addition to the benefits of the HM140 roller, the HM150 series rollers are equipped with a flow formed roller shell.
The flow forming process delivers a shell of exceptional roundness and increased hardness, which is a key to success in mining conveyors and similar equipment. An increased wall thickness at the center of the shell allows for better loading capabilities with lower shell deformations. Flow formed rollers do not require machining and balancing, as TIR is extremely low and shell thickness remains constant, leading to better and long-life operation.
HM150 formed roller can be used as a garland roller or traditionally installed onto a roller frame.
Key specifications
| Roller diameter | 159, 178, 194 and 219 mm |
| Shaft diameter | 40, 50 and 60 mm |
| Roller length | 380 - 1450 mm |
