Clutches and brakes as well as torque limiters continue to evolve as the requirements for new applications for holding, stopping, and indexing continue to multiply. The ongoing trend for these technologies towards application-specific variations continues unabated — especially as several industries have exceeded capabilities of legacy stock parts. “Mach III has experienced a strong increase […]
New SmartSense24 sensorless brake and clutch monitoring from Regent Controls Inc.
Regent Controls, a Carlyle Johnson Company, now sells a SmartSense24 Sensorless Brake or Clutch Status Monitor. The first product of its kind, SmartSense24 controls and monitors spring-applied electrically-released brakes and clutches — increasing the life of these motion components. The controller provides real-time status and wear condition on an LED display by electronically sensing armature […]
New BXW model spring-actuated brakes from Miki Pulley
Miki Pulley’s BXW spring-actuated electromagnetic brakes provide reliable dynamic braking when the power is disengaged and excellent performance in long-term holding applications. BXW brakes use internal compression springs to provide power-off, fail-safe braking. The primary moving part in this robust but simple brake design is the armature plate. When actuated, the brake compression springs push […]
Video: What is a torque limiter?
Torque limiters are mechanical and electromechanical power-transmission devices that protect machine sections (or workpieces they’re servicing) from overloads, crashes, and damage from jams. Torque limiters work either by slipping or completely disconnecting the drive from the driven load. Some torque limiters of the former type (especially those employing friction plates) are also called slip clutches. […]
New micro brakes for servo motor applications from Ogura
A new line of micro brakes from Ogura is designed specifically for servo motor applications, especially in robotics and medical equipment. Ogura micro holding brakes come in both square and round designs with the newest round design being 10 mm in diameter with length is as short as 9 mm. Micro brakes can weigh 20 […]
Miki Pulley introduces BXH “Lock-In-Place” brakes
“Lock-In-Place” Brakes from Miki-Pulley provide long-term positioning for direction control wheels on picking forklifts and similar applications. Designed for both braking and holding, these Power-Off engaged BXH model brakes from Miki-Pulley are opened using an electromagnetic field, and hold in a default closed position with compression springs. They have double the torque of similar brakes […]
New Marland BCMA backstop now has an automatic lubrication system
Marland Clutch now offers an automatic grease lubrication system that eliminates the need to manually grease the labyrinth seals of its Marland BCMA backstops. In many instances, Marland BCMA backstops are located in difficult-to-reach areas making regular grease maintenance very difficult. By installing the new automatic lubrication system, regular grease maintenance is performed, but no […]
Oil-shear technology clutch/brakes from Force Control eliminate maintenance, adjustment
Force Control Industries presents their Posidyne X Class Clutch Brakes which feature Oil Shear technology that allows rapid and precise stopping, starting, reversing, speed change and positioning – all without adjustment and virtually no maintenance. Well suited for applications with frequent start/stop cycles, these unique motion control devices allow higher cycle rates (as high as […]
Using mechanical torque limiters to protect servo-driven machinery
Servomotor-driven machinery abounds in today’s automated applications. These designs typically require high speeds for top throughput, dynamic operation for nimble positioning, and (in many cases) quick reversals for indexing. So it’s key to have some means to: Protect the servomotor from damage by sudden load changes, over-torque conditions, or shock due to machine issues. The […]
Electromagnetic brakes provide more stopping power for servo motors using less space
The BXR-LE brake series from Miki Pulley is a power-off, engaged brake design. When the stator is energized, the brake is disengaged allowing free rotation. When no current is applied, compression springs halt the brake rotor thereby stopping the input shaft rotation. This is an ideal feature to prevent rotation during power failure events. The […]
