Keiper PORUFLEX belts
Since we strive to guarantee the best possible properties for any application, we use premium raw materials from leading manufacturers to produce our PORUFLEX belts. They are available as round belts, V-belts and with special profiles and, thus, suitable for myriad power transmission and conveying applications.
PU round belts
We have a complete range of polyurethane round belts for conveying and power transmission applications. PU round belts, available in open lengths, are extruded and homogeneous round profiles that can be welded for use as high-quality power transmission and conveying elements.
Our stock mainly comprises solid profiles with a smooth or slightly roughened surface and hollow profiles for nipple connections. Several types have FDA/USDA approval and comply with EU Directive 2007/19/EC. Although we generally produce in open lengths, we can also produce all belts according to your specifications. Our round belts convey a wide range of products such as foodstuffs, glass, roof tiles, PC boards and many more. The standard range of round belts is rounded off with aramid, polyester or glass-fiber reinforcements.
Round hook belts
Round hook belts are the ideal solution for power transmission or conveying systems where several belts run on one shaft.
Since they are easy to install, downtimes and maintenance costs can be reduced significantly.
Endless extruded round belts
Our endless extruded round belts are ideal for low power requirements. They are elastic power transmission elements that do not need cost-intensive tensioning devices. In view of the special production process, they do not have any welding seams or terminal connections, which lets them run very smoothly. Moreover, they allow a minimum pulley diameter starting from 5.5 x belt diameter.
Endless turned round belts
Our endless turned round belts are wound either out of one homogeneous strand or one cord and spliced endlessly without thickening. For special applications, it would be possible to vulcanize the inner splice or to make a special splice based on our in-house engineering methods. This increases the tensile strength by up to 60%. In elastic types, the core is welded.

Our core competence is the complete manufacture of complex drive engineering elements and components.
With modern CNC machines, we manufacture precise components for industrial use according to the quality requirements of our customers.
State-of-the-art CNC sawing machines guarantee only a minimum of waste and, due to their small measurements, the optimisation of subsequent cutting times.
As a supplier, we have acquired extensive knowledge in dealing with renowned companies of machine and plant construction and in the conveyor system sector.
Years of production experience and technical expertise mean we are a partner who can quickly and reliably cater for the demands of our customers.
In order to meet the rising quality requirements of our customers, it is our objective to improve our quality standards and to render them documentable and measurable using state-of-the-art test methods. In so doing, we rely on a measuring machine produced by Zeiss.
To us, the high quality of products and processes is a precondition for the smooth processing of orders. This claim results in a high level of reliability, combined with the flexibility of a modern medium-sized business.
