Bronze with graphite inserts.

Self-lubricating.
Hardness 190-220 HB.

The guide bushes are radially and axially applicable.
The bearing elements are maintenance-free and wear-resistant.
The graphite inserts provide life-long lubrication.

Preferably for travel speeds < 0.5 m/s. (Additional lubrication is recommended for extreme loading with a higher travel speeds).
