GE Industrial Control Components IC9528 DC Spring-set Shoe Brakes

AISE and NEMA Rated—IC9528

600 Volts Max

Where to use

Use as holding, stopping, or retarding brake on cranes, hoists, conveyors, movable bridges, rolling-mill drives and other machinery. The brake responds quickly to prevent the load from drifting or coasting after power is cut off.

The IC9528 brake is a two-shoe, spring-set brake operating on a wheel mounted on the shaft of a motor or other machinery. When energized, a dc magnet picks up against spring pressure to effect release. When deenergized, the magnet drops out and the brake is set by the operating spring. The IC9528 brakes now incorporate non-asbestos brake linings.

IC9528 brakes meet AISE and NEMA standards for shoe brakes. They are designed for use in a 40 C ambient.

The C and E forms provide for additional torque capacity through increased lining area.


1. Single-end Adjustment
Simple agjustment for (A) lining wear, and (B) torque setting.
2. Enclosed Terminal Box
Totally enclosed conduit box for terminating coil leads.
3. Epoxy-encapsulated Coils
Dirt, moisture, and oil are sealed out.
4. Manual-release Mechanism
Permits removal of wheel or replacing brake linings without adjustment of torque setting.
5. Armature-gap Indicator
Clearly visible indicator shows when to adjust for lining wear.
6. High-Strength Ductile-iron Wheel
Material chosen for high tensile strength and wear-resistant qualities. Wheel is removable vertically to speed motor servicing. By simply pivoting the tie rod on the 30-inch brake, the wheel can be removed vertically.
7. Non Asbestos Bonded Lining
No need to remove shoe assembly to replace lining. Simply utilize manual-release mechanism, remove lining-retaining bolts and slip lining out with screwdriver. Lining is non asbestos material bonded to steel backing.
8. Self-lubricated Bearings
Self-lubricated bearings with stainless steel pins.
9. Self-cleaning Armature (cut-away)
Cut-away design allows dirt to fall through rather than collect in armature gap.
9A. Self-cleaning Armature (top-pivot)
Top-pivot design allows dirt to fall through rather than collect in armature gap.
10. Shoe-clearance Locking
Positions pivot arm to provide positive shoe clearance.
11. Complete Magnet Interchangeability
The complete magnet housing with its coil is readily interchanged. Can be removed vertically if desired.
