Smooth guide bushing 23680

Guide bushes bronze, maintenance-free Material: Bronze with graphite inserts. Version: Self-lubricating. Hardness 190-220 HB. Note: 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).
