FAM® L / MANGAChOC
FAM bushings are manufactured from manganese steel, which provides excellent resistance to abrasive wear thanks to mechanical work hardening effect of the contact area. Only an initial greasing is required.
FAM bushings have internal cross hatched topography that provides an excellent distribution of grease and enables the removal of abrasive contaminants from the contact area
FAM L or MANGACHOC bushing have smooth internal diameter. They are mainly used for their high resistance to abrasion and high contact pressure in shock load working conditions, with no maintenance.
MANGACHOC technology is also available on spherical plain bearing in case of angular misalignment or flexion in the joint.
Mating Shaft:
Shafts hardened for 56 to 60 HRC are recommended. For optimal performances of the joints, special shafts are available from HEF DUFERRIT: FAM ST, FAM HT, FAM OX.
