Savepol Poliuretany offers professional shafts and rolls protection against abrasive factors. Reliability of our protecting coats results in minimizing losses during production stoppage (repair), taking into consideration assembling during replacement the shafts and stoppage periods connected with this fact.
We mainly protect the following shaft surfaces:
- leading shafts,
- distributing shafts,
- under-sieve shafts,
- pressing shafts,
- register shafts,
- belt rolls,
- drums,
- low-loaded rolls.
We mainly perform coatings on shafts and rolls for paper factories and papermaking industry, protection of shafts and rolls used in cold rolling in steelworks, protection of shaft surfaces for woodworking industry, textile industry and others.
Main advantages of offered protection coats:
- high resistance to abrasion and friction which extends effective worktime of device,
- better shock absorption and as a consequence reduction of vibrations,
- high tearing strength,
- high hardness allows circular motion,
- can be applied both in dry and wet, erosion environment,
- high flexibility,
- high resistance to hydrolysis,
- very high coating density,
- smooth surface, no welds,
- non-toxic.
We also perform untypical orders, we choose materials and technologies on client request. We ensure high quality and aesthetic completion as well as long-standing guarantee for chosen program.

On client’s request we can also produce coats with different hardness and with different mechanical parameters.
In these coats we use polyurethane with rubber-like properties but it has got much better usage parameters that traditionally used rubber, metal or ceramic coats. Much higher polyurethane strength and possibility to choose hardness enable to obtain lighter and fully vibration damping elements which extend effective worktime of device and minimize losses during production stoppage. Materials used by our company as well as technologies of applying them are much safer for environment.
