Components for the agricultural sector are usually exposed to various environmental influences and strong physical stresses. They must be resistant and should remain serviceable for as long a period as possible. Should individual components fail, this can have serious economic consequences, as the periods during which sowing and harvesting can take place are limited.
Above all, material combinations of rubber and plastic allow reliable and consistent use of the machines, as they provide the necessary robustness despite their low weight and without the risk of corrosion.
Seed drills use pressure rollers to regulate the depth of seed placement and for soil compaction after the sowing process. Previously drawn furrows are closed to prevent the seed from lying open in the field. For this purpose the press rollers must work permanently with appropriate pressure and on different types of subsoils.
The JÄGER Group manufactures assemblies made of high-strength rubber and highly resistant plastic for this purpose in order to withstand the extensive influences such as abrasion and specific force-displacement behaviour. The penetration of dirt into the pressure roller bearing is optimally prevented by a well thought-out construction of lip seals and dust caps.
