Our Rub­ber-Plas­tic Elements 

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.
