Brake With Follower Arm
These provide constant tension when used in dedicated
payoff applications. The device is ideal for paying off
wire, cable and a variety of films and tapes where constant
tension is required.
Available in 3 torque ranges.
Bearing-supported magnetic cap for smooth arm movement
Bearing-mounted Delrin wheel
Stainless-steel self centering
All magnetic, no electricity,
no wearing parts
The magnetic brake is mounted as shown, central to payoff
spool at a fixed centerline distance (CD) which is determined
by pulley ratio from brake to spool shaft and timing belt.
The adjustment arm attached to magnetic brake has a Delrin
wheel riding on diameter C following material down as material
pays off to B. This arm angle change decreases the braking
torque to maintain constant line tension throughout spool
payoff from C to B. The pulley ratios determines the final
torque transferred to spool shaft to achieve desired line
