MAGPOWR Global Series BrakesRead More
Versatility and flexibility are the real benefits found in MAGPOWR’s Global Series Magnetic Particle Brakes, as they provide smooth, repeatable, controllable torque independent of speed. This makes them suitable for all kinds of power transmission and tensioning applications. Sizes are available from 5.5 to 325 lb-ft of torque.
This line of brakes features state-of-the-art magnetic particle technology and its compact size is due to through-bores on all machined housings for ease of mounting. The M (Metric) series boasts full metric bores and keyways, as well as metric mounting hardware and setscrews to support international design requirements. The brakes are also available as 24 vdc or 90 vdc.

B Series Magnetic Particle BrakesRead MoreB Series Shaft Mounted Magnetic Particle Brakes give operators exactly what they want: high-quality, dependable performance with no headaches. The magnetic particle brake is an inherently simple, durable device. They are easy to install, made of rugged cast iron for long life and have minimal moving parts, meaning the brakes can be mounted and start performing immediately.
MAGPOWR B-7V and B-20V Vertical Magnetic Particle BrakesRead More
Unlike other magnetic particle brakes, a horizontal axis is not required for shafts utilizing MAGPOWR’s B-7V & B-20V Vertical Magnetic Particle Brakes, thanks in particular to the unit’s disk-shaped rotor. Other brakes sport cylindrical designs, requiring a horizontal shaft axis. The B-7V & B-20V operate with the axis vertical, horizontal, or at any other required angle—the space between the rotor and the two sides is filled with magnetic particles, so the unit can be operated in any orientation.
MAGPOWR’s B-7V & B-20V Vertical Magnetic Particle brakes, made of rugged cast iron for long life, are easy to install and have minimal moving parts, requiring very little installation and calibration. These brakes assist in smooth, repeatable torque that is proportional to current, and applications include tensioning of film rolls on vertical shafts, packaging machines and machine tools.
Tidland Mark I and II Roll SaversRead More
Save your crushed core with Tidland’s Mark I or Mark II Roll Savers. These roll savers are designed to re-open crushed cores, allowing for shaft insertion on rolls that would otherwise be considered scrap material. The Roll Saver provides a return on your investment with its first use as the cost is comparable to that of a damaged roll, creating a positive impact on profit margins and warehouse space. Air shafts cannot be inserted into rolls with even with the slightest deformation, leaving damaged rolls useless. With a Tidland portable hydraulic Roll Saver, rolls can be salvaged.
Cooling Options for MAGPOWR Clutches and BrakesRead More
Used under slip conditions, MAGPOWR Clutches and Brakes generate significant heat that must be dissipated. Often, that heat is dispersed via that model’s convection cooling ability. If the application exceeds the dissipation capacity of a convection cooled model, additional heat dissipation capacity can be achieved through the addition of MAGPOWR’s forced air or water cooled options. The addition of these accessories can increase the heat dissipation capacity by 300-500 percent.
FORCED AIR COOLED: The air hood and blower assembly is a pre-assembled shroud that forces air from the blower through the clutch or brake. Forced air-cooling is particularly useful on applications having a low RPM unit. Factory assembled units with this option are designated by the letter “A” after the model number.
WATER COOLED: In these units water is forced into the hollow rotor through a tube in the shaft and is returned through the shaft to the special water fitting or coupling. Water-cooled clutches and brakes are designated by the letter “W” after the model number. Water fittings must be ordered separately.
FORCED AIR & WATER COOLED: The Forced Air and Water Cooled combo on a MAGPOWR unit gives maximum heat dissipation capacity. Factory assembled units with both options are designated by the letters “WA.”
OVERSPEED CONTROL: An additional option to these cooling methods on rewinds is to use the ‘inverse diameter’ option available with some of our open loop and closed loop controllers. The controllers limit overspeed and thus heat as a rewind roll grows in diameter and the rpm slows.
MAGPOWR Digital Tension MeterRead More
A low-cost way to monitor tension output, the Digital Tension Meter (DTM) is perfect for applications where access to tension control parameters is not required. Operators can mount a control away from the web to get feedback on current web tension via a backlit display and illuminated digits. The DTM is encased in high-impact plastic to withstand demanding conditions. A sealed front panel meets industry-standard NEMA 4X/IP65 specifications for wash-down and dusty environments. This meter can be used with any tension sensor amplifier by reading the 0 to 1 mA meter output reference.
MAGPOWR TR-5Read More
The MAGPOWR TR-5 Tension Readout is a device for measuring tension in a moving web, strand, wire or narrow tape. It uses either one or two MAGPOWR load cells and interconnection cables.
This system can be used on any non-driven idler roll or at any position where the wrap angle of the web or strand does not change. Each load cell contains four foil type strain gages bonded to a sensing beam. These gages convert the load on the roll or sheave to an electrical signal. Within the TR-5, the signal from the load cells is amplified and displayed on the tension meter.
The amplifier of the TR-5 has low drift and high linearity, with a gain control range of 8:1 and tare adjustment of 50%. An auxiliary 0 to 10 VDC, or 4 to 20 mADC output is provided for interfacing to other products or systems.
MAGPOWR TS Load CellsRead More
TS Load Cells provide the most consistent control of tension, no matter how the temperature changes throughout the day. In fact, all MAGPOWR Load Cells are designed with foil strain gauges that provide the lowest temperature drift rating possible (.02% per º C), which can mean the difference between a profitable web and a floor of wasted material.
These rugged load cells are extremely accurate devices used to measure tension in any unwind, rewind or intermediate web processing application. The unique low profile design minimizes space requirements inside the machine frames, thus maximizing the potential for web width. TS load cells are designed with mechanical overload stops in both force directions to eliminate sensor damage and the need to recalibrate even after extreme overloads, while also offering the flexibility of a variety of mounting styles and coupling options.
Split coupling models
Load Cells with Split Couplings can be used to measure web tension through dead-shaft or live-shaft idler rolls. With one load cell mounted to each side of the machine frame, the idler roll is supported between the two load cells. The resultant force of the web tension is measured as a load on the roll by the load cells.
The Split Coupling allows the idler roll to be easily installed after the load cells have been mounted to the machine frames. The coupling design also accommodates misalignment between the machine frames and allows for thermal expansion of the idler roll shaft during machine operation. The unique coupling design also allows its use in both dead-shaft and live-shaft applications.
In-roll coupling models
The In-Roll Coupling is designed to insert directly into the end of an idler roll. With one load cell mounted to each side of the machine frame, the idler roll is supported between the two load cells. The resultant force of the web tension is measured as a load on the roll by the load cells.
The In-Roll Coupling includes a spherical bearing to allow for smooth rotation of the idler roll and to accommodate misalignment between the machine frames. This coupling type eliminates the need for idler rolls with shafts and bearings, thus reducing the overall cost of the tension sensing system.
Wire pulley models
The Wire Pulley is used for single strand applications for any kind of material. When mounted to the side of a machine frame or bracket, a load cell measures tension in the strand as it passes over the nickel plated aluminum load cell pulley.
