Use the model designation in the catalog legend as an initial moment-and-thrust capacity reference.
This catalog chart is a preliminary selection aid. Final MERYDOM application approval must also consider mounting rigidity, bolt capacity, duty cycle, lubrication and operating conditions.
This MERYDOM bearing has been reviewed against the published model envelope, mounting interfaces, gear configuration and declared material specification for replacement use.
Send the required quantity and operating conditions. MERYDOM will confirm the supply configuration, documentation package and delivery schedule for model 31-20 1400/2-06710.
