Marland has been producing overrunning clutches since 1931. Primary Marland products are backstops, clutches and clutch couplings utilizing either the principle of cylindrical rollers on inclined cam planes for low speed applications or sprag technology for high speed requirements. Worldwide installations range from food processing plants to equipment used in steel mills and heavy mining industries. Marland one-way clutches and backstops have been protecting costly equipment, preventing injury and preventing lost production time for over 60 years.

Marland low speed backstops are mounted on conveyor headshafts to automatically prevent any reverse rotation of the headshaft or movement of the conveyor during a scheduled or un-scheduled stoppage under load.   Marland high speed backstops include inner race centrifugal throughout sprag designs and fully releasable models, low speed backstops see catalog P-1469.
