MAINTENANCE
CAUTION: Before attempting to service or remove any components, make certain that the power is disconnected and
that the load is completely removed, secured or blocked to prevent injury or property damage.
Wear Adjustment
CAUTION: Load to be removed or blocked. Brake may be inoperative during this procedure.
Before air gap “D” reaches .100”, adjustment is required. Any delay in adjusting
the magnet air gap will result in eventual loss of torque. Refer to Fig. 1, 2 & 3.
1. To adjust, remove cover locknuts/seals (70 & 71) and cover (67) to expose
wear adjusting screws on item (32) and expose magnet air gap “D”.
2. Measure air gap “D” using 3/8” to 1/2” wide feeler gauge.
Measure at center of magnet.)
3. Turn two adjusting screws on item(32) until air gap “D” measures:
.035/.045 for 1 disc models
.035/.045 for 2 disc models
.045/.055 for 3 disc models
.055/.065 for 4 disc models
Air gap should be the same on both sides.
Torque Adjustment
Caution: Load to be removed or blocked. Brake may be inoperative during this procedure.
The magnetic disc brake is factory set for rated static torque. The brake can be adjusted to reduce torque which increases
stopping time. Do not attempt to adjust brake for higher torque, as this will cause premature coil burnout. (Refer to Fig. 1 & 2)
1. To adjust, remove cover locknuts/seals (70 & 71) and cover (67) to expose torque locknuts (44), which are above torque
springs (42).
2. To increase stopping time and reduce torque, turn two locknuts (44) counterclockwise, increasing spring length.
Each full turn reduces torque 7% to 10% depending upon the model.
