Sinfonia Technology Co., Ltd. SBS-140-8D Brake

The Sinfonia Technology SBS-140-8D is a spring-closed electromagnetic brake from the SBS family, designed to hold or stop motion in machine tools and automation equipment when power is removed. Built around the SBS-140 frame, the SBS-140-8D variant is offered with a 24 V DC coil and about 28 W of coil power, a configuration commonly documented in supplier listings for this model. This brake is intended for reliable, fail-safe braking in automated systems, providing consistent engagement and release characteristics that support safe stopping sequences for spindles, feeders, and other actuators used in precision machining and automation. As part of the SBS line, it complements other SBS-140 variants (such as 4D and 8D) and integrates with standard mounting patterns within the 140-series footprint, enabling straightforward replacement or substitution in compatible assemblies. Typical applications include holding loads on rotating or translating components in CNC machines, presses, conveyors, and other equipment where a power-off brake is required to maintain position or provide an emergency stop. Designed for durable operation in industrial environments, the SBS-140-8D delivers the essential performance of a spring-applied brake without the need for continuous energization to maintain braking, making it a dependable choice for maintaining safe, controlled motion in manufacturing and automation workflows.
