How do shear pin torque limiters work and when are they used?
Shear pin torque limiters are a simple, cost-effective design for protecting equipment from torque overloads. In their most basic form, they incorporate a pin (or, for very high torque ratings, multiple pins) inserted between two rotating elements, such as discs or flanges. When torque is being transmitted from the driving to the driven load, the […]
How do ball detent torque limiters work and when are they used?
Rotating equipment such as motors, gearboxes, and fans can experience a torque overload if the system encounters an unexpected malfunction such as a jam or crash of the driven load. One way to protect these expensive components — and to avoid physical injury to personnel — is to install a torque limiter in the drive […]

Extra thin emergency and holding brakes for compact automated systems
Miki Pulley’s unique BXR power-off engaged brake can serve as an emergency brake, as well as a holding brake, important for protecting compact designed automated systems. These BXR spring applied brakes provide versatility in space and weight savings. Their unique, low-profile design is 2/3 the thickness of other brakes in the Miki lineup. The brakes […]
Balancing power, weight, and efficiency objectives with low-power braking
Engineers who want the smallest, lightest, lowest power brake available should talk to their brake supplier in the earliest stages of the design project. Waiting until later in the process will trigger a compromise on one or all three of these important design considerations. By Brian Mather | Industrial product manager • Ogura Industrial Corp. […]
KEB America debuts high capacity spring-set load brakes
KEB America’s new High Capacity Load brakes use a spring-set (power-off) design and are electrically released. The brakes are offered in graduated sizes up to 3,200 Nm (2,360 ft-lb). “These brakes are ideal for critical lifting applications that require secondary braking, including cranes, hoists, and lifts”, notes KEB Marketing Manager, Jonathan Bullick. The brakes feature […]
Brakes for elevator and lift applications from Miki Pulley
Spring-actuated BXL Brakes from Miki Pulley are designed for the challenging requirements of elevator and lift applications. Designed exclusively for dynamic braking, these brakes are designed for constant elevator usage where long service life with high wear resistance is required. BXL Brakes feature minimal torque fluctuation, even when stopped from maximum RPM. This ensures a […]
Posidyne clutch/brakes suitable for indexing conveyors, palletizers
Posidyne clutch brakes feature oil shear technology for rapid and precise stopping, starting, speed change and positioning, all without adjustment or maintenance. They are suitable for applications with frequent start/stop cycles, such as indexing conveyors that feed palletizers, rotary tables, batch feeders, rotary coal samplers, cutoff machines, and more, these unique motion control devices allow […]
Miniature brakes: Examples of where electromagnetic spring-applied versions excel
Many industries have come to employ the compact cameras, sensors, batteries, processors, and communications technologies made ubiquitous by consumer products. Electromagnetic brakes complement such designs with miniature formats. By Brian Mather | Industrial product manager • Ogura Industrial Corp. Oh, how times are changing. Zoom meetings are the norm. Children all over the world […]
