Power, not downtime – productivity, not waste
Whether you want aluminium rollers with outstanding free-running properties, steel or stainless steel rollers for a high level of stability, stainless steel rollers for a high level of resistance to corrosion or CFRP/GFRP rollers that meet the most stringent rigidity, endurance limit and weight restriction requirements, our skilled employees and our seamless documentation processes ensure that we can guarantee top quality on which you can rely.
AST® rollers are all available with standard surfaces such as eloxal, rubber or chrome, or with a THERMCOAT® coating.
AST® rollers have outstanding properties:
- Smooth running at high speeds
- Low starting torques
- Very quiet running
- Narrow production tolerances
- Low breakaway torques
Our innovations for your success
At AST®, all of the rollers are developed and manufactured in-house. This puts us in the position of constantly being able to initiate product innovations. Our work results in tailor-made rollers with functional, high-precision surfaces for maximum process reliability and efficient results.
Aluminium rollers with carbide coating
Free-running rollers with a hard (>1,400 HV 0.3), very wear-resistant, cut-resistant, zero-pore and high-gloss polished surface (Rz < 0.5 μm) are a good alternative to heavy, sensitive chrome-plated steel rollers. Steel rollers with a ceramic coating Steel rollers with a ceramic coating, which we developed for a very corrosion-resistant surface, can replace complete stainless-steel rollers. The resistance to corrosion has been certified by a salt spray test according to DIN EN ISO 9227 lasting over 1,000 hours. CFRP/GRP rollers with carbide coating Composite roller with a ceramic or carbide coating impress with their very high resistance to wear with surface hardnesses in excess of 1,400 HV 0.3 and a surface finish of Rz < 1 μm.
