Installation and maintenance points:

Before installation, clean the trunnion groove and fixing device surface to remove oil and rust, ensuring the retaining ring is elastic and free from deformation or cracks.

First, press the bushing into place, then insert the locating ring into the bushing locating groove. Finally, use retaining ring pliers to install the elastic retaining ring into the trunnion groove, ensuring the retaining ring is fully engaged at the bottom of the groove.

Post-installation inspection: The fixing device should not be loose or misaligned; the axial movement of the bushing should be ≤0.05mm; the retaining ring opening gap should be uniform.

Maintenance: Check the fixing device condition every 1200 working hours. Replace if the retaining ring is deformed, corroded, or the locating ring wear exceeds 0.2mm.
