FAQs
The 7BBM3112 is designed for foot mounting on frame size 56 with a standard drive end flange, supporting 3-phase operation at 208 V, 230 V, or 460 V and 60 Hz. It is suitable for open enclosure applications, enabling straightforward retrofits into existing conveyors and machine-tool lines. Verify shaft diameter of 0.63 in and ensure compatible enclosure mounting on the equipment side.
With 0.75 HP rated output, 1725 rpm nominal speed, and a service factor of 1.25, the brake delivers a reliable stop and hold in continuous-duty cycles. The 208/230/460 V options and 60 Hz operation support common industrial drives, reducing mismatches and allowing more predictable torque during deceleration, which minimizes belt slip and product damage in material handling systems.
Yes, the 7BBM3112 features an OPEN enclosure design and a standard NEMA B designation, making it compatible with open-mount installations common in non-hazardous factory floors. For harsh environments, plan protective measures and verify regional certifications (CSA/UR) to ensure compliance with local electrical and safety standards before deployment.
This unit is stocked across multiple warehouses with a 0 day lead time, enabling rapid fulfillment for urgent automation projects. Stock locations include US and international facilities, helping to mitigate supply chain disruptions. Always confirm current stock at your preferred distribution center to align delivery with project schedules.
The brake is designed for reliability with a 0.75 HP rating and regreasable lubrication, supporting consistent performance between maintenance intervals. ROI benefits come from reduced downtime due to fast, repeatable braking, easier installation with standard mounting, and broad stock availability that lowers procurement risk on long-term OEM and after-market projects.
