In the article What are functional safety standards for servo drives? we review how functional safety is quantified. Now consider one example of a spring-set pneumatically released friction servomotor brake now having a third-party safety rating (from Intertek Group) certifying compliance with international safety standard ISO 13849-1. Intertek is an international London-headquartered inspection, assurance, product […]

Power-off engaged brakes for conveyor applications
Miki Pulley’s latest model BXW power-off engaged brakes are designed to halt a motorized conveyor roller when system power is disengaged. These new BXW brakes are spring-actuated electromagnetic brakes. They provide reliable dynamic braking when conveyor power is disengaged and excellent performance for longer-term holding requirements for staging, loading and unloading conveyor operations. BXW brakes […]
Inductive proximity and magneto resistive sensors enhance IoT4.0 connectivity for Nexen brake families
Nexen Group, Nexen Servo, Rail, and ZSE brake lines now have Industry 4.0 connectivity sensor options to enhance machine efficiency. Multiple sensors integrated into the brake families provide information about brake operation and health to the control system network. The sensors used in the spring-operated air-released ZSE brakes provide operation information such as brake engagement […]
Podcast: Dave Hein of Nexen Group on brakes having functional safety certification
In our most recent Technology Tuesdays podcast, Dave Hein — senior vice president and engineering and chief technology officer at Nexen Group — chatted with us about three brake options that now have Functional Safety certification. Listen in: Design World · Brakes with Functional Safety certification: Update from Nexen Group engineer Dave Hein According […]
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 […]
Brake and clutch manufacturer Mach III has new website at machiii.com
Mach III, Kentucky-based designer and manufacturer of custom and standard brakes, clutches, and torque limiters (to connect and disconnect, stop, hold, tension, and protect machines and operators) now has a new website at machiii.com. Better features. Better options. Better hurry and check it out … The new Mach III website includes reorganized content, streamlined navigation, […]
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 […]
