① Driven Pulley：
Main driving component for centre drive belt conveyors:
Select BP-D series pulley (rotating shaft).
② Head & Tail Pulley：
Installed at each end of a belt conveyor according to the different drive type and structure:
a、Centre drive:
Change the belt direction: Select BP-R series pulley (fixed shaft) or DP-D series pulley
(rotating shaft)
b、Head or Tail drive:
Drive Pulley: Select BP-D series pulley (rotating shaft)
Idler Pulley: Select BP-R series pulley (fixed shaft) or BP-D series pulley (rotating shaft).
③ Snub Pulley：
Used to increase the belt wrap angle for the driven pulley, tension and tracking the belt.
Select BP-R series pulley (fixed shaft).
Be careful about the belt tensionning and siding focce when using as redirection & tensioning.
④ Carrying Roller：
Used to support the belt, simplify structure and reduce friction:
Select 1200 series conveyor roller.

This series is primarily used for belt idler rollers.
When used for steering and tensioning rollers,
due to the design of the product itself,
it is essential to control the belt tension and lateral forces.
Experience has shown that even when the belt’s wrap angle is not large,
the generated tension force (alternating load) can still cause abnormal operation or even damage to the rollers.
