Installation, operation, and maintenance manual for the Magpowr HEB250 pneumatic high-efficiency brake.
The Magpowr HEB250 is a pneumatic high-efficiency brake with a 250 mm rotor used to create web tension in an unwind roll. This manual covers theory of operation, model numbering, rotor bore codes, caliper positioning, dimensions, safety information, and mechanical installation.
Caliper configurations range from one to six, with low, medium, or high friction pads, an optional cooling fan, and an optional proximity sensor. The document also lists standard rotor bores and set-screw tightening torques.
| Rotor diameter | 250 mm [10 in] |
|---|---|
| Caliper configurations | 1 to 6 calipers |
| Low friction coefficient | 0.12 |
| Medium friction coefficient | 0.41 |
| High friction coefficient | 0.51 |
| Proximity sensor output | 1 pulse per revolution |
| Cooling fan | Optional |
| Operating environment | Indoor only |
| Actuation | Pneumatic pressure |
It is an HEB250 with four calipers, medium coefficient friction pads, a fan, a proximity sensor, and a 28 mm rotor bore.
The maximum number of calipers with pads is five, because one caliper is used to mount the sensor.
It is intended for indoor operation only.
Low is 0.12, medium is 0.41, and high is 0.51.
