The Functions Of Mast Roller Bearing ? 

Mast Guide Bearing play a important role for fork lift trucks, Mast bearings can carry the forks (carriage) up ,the mast and the bearing can also adjust the mast tothe different stages .

There are four type mast bearings.

1.Forklift Mast Roller Bearing  – these bearings guide the mast stages up as the forks are raised beyond the first stage. They also attach the fork carriage to the mast rails.

2.Carriage bearings – these provide lateral guidance to the fork carriage as it travels up the mast. They are typically smaller than the mast guide bearings.

3.Forklift Side Roller Bearing  – these bearings transfer the lateral (sideways) loads to the mast and help to prevent twist. Typically they are mounted on a shaft (pin).

4.Forklift Chain Pulley Bearing  – these guide the leaf chain that raises & lowers the mast. The bearings are usually flanged like a pulley to ensure the chain is captive.
