LASTO-BLOCK F is an unreinforced elastomeric bearing of NR (natural rubber) or CR (chloroprene rubber). The use of high-capacity elastomer enables the bearing to transmit high pressures of up to 20 Nmm2 while also compensating a significant rotation or parallel displacement. For use in exposed conditions and for heightened demands in relation to chemical resistance, LASTO-BLOCK F of CR (chloroprene rubber) is recommended.
