Bearing for Forklift Trucks MAST ROLLER BEARING Mast roller bearing is used to guide for linear movement of forklift truck s mast.

It is designed to special bearing for withstand repeated extreme impacts and heavy radial load in harsh environments.

CHAIN SHEAVE BEARING Chain sheav ve bearing is used to axis of the chain for vertical movement of a fork carria age.

It is designe ed to special bearing for withstand eccentric load, heavier radial load and corrosion in harsh environments.

5 Bearing for Forklift Trucks MAST ROLLER BEARING Mast roller bearing is used to guide for linear movement of forklift truck s mast. It is a core part of the mast and has a role of guide and retain movable fork carriage to mast. It is designed to special bearing for withstand repeated extreme impacts and heavy radial load in harsh environments. Special designed thicker outer ring, closed-die forged materials and bearing-exc exc clusive case hardening heat treatment makes more impact resistance and durability. CHAIN SHEAVE BEARING Chain sheav ve bearing is used to axis of the chain for vertical movement of a fork carria age. It is a core part of the mast and has a role of lift and lowering of the fork carriage by sustaining chain belt in axis. It is designe ed to special bearing for withstand eccentric load, heavier radial load and corrosion in harsh environments. Special des igned snap ring, various surface finishing, closed-die die forged materials an nd bearing-exclusive exclusive case hardening heat treatment makes more eccen tric, heavy radial load and durability. SIDE ROLLER BEARING Side roller bearing is used to hold side load occurred by vertical movement of fork carriage. It is a core part of the fork carriage and has a role of side guide and retain movable for rk carriage to mast. It is designe ed to special bearing for heavy radial load with limited diameter. Special des igned multi-row bearing, closed-die die forged materials and bearing-exc exc clusive case hardening heat treatment makes heavy radial load and durabilit ty with limited space. 5
