Warner Electric 5371-271-009 Clutch

SERIES DESCRIPTION

The Warner Electric UM Series UniModule line features completely pre-assembled, one-piece clutch and clutch/brake packages engineered for maximum performance and direct installation convenience. Factory pre-aligned and pre-burnished to deliver full rated dynamic torque right out-of-the-box, these enclosed, maintenance-free units easily mount to standard NEMA C-face motors and reducers or operate as separate drive units via an accessory base. Available across five compact sizes with options for power-on or power-off electrically released configurations, the UM series utilizes a symmetric finned housing and integrated fan cooling to reliably sustain high cycle rates in demanding industrial indexing applications.

FEATURES

• Factory Pre-Burnished: Packages are completely assembled, aligned, and run-in at the factory to achieve rated torque immediately upon field installation.
• Patented Autogap™: Built-in mechanisms automatically adjust armatures to compensate for mechanical wear, maintaining proper running gaps and ensuring maintenance-free longevity.
• Optimized Heat Dissipation: Constructed with a high-efficiency symmetric housing fin design and standard fan cooling to sustain high cycle rates and guard internal coil insulation integrity.
• Heavy-Duty Concentricity: Utilizes premium, rigid internal bearing arrangements to preserve tight shaft concentricity, minimizing running noise, vibration, and component wear factors.
• Asbestos-Free Friction Faces: Built using long-life, high-torque friction materials that facilitate clean, predictable stop and start operations.
• Simplified Conduit Access: Housing designs feature single conduit entrance areas situated cleanly on top of the units via integrated mounting bolts, keeping installation fast and simple.
• Enclosure Versatility: Vented layouts can be easily upgraded in the field using quick conversion cover kits to generate totally enclosed, non-washdown environments without swapping the assembly.

SELECTION PROCEDURE

1. Select Unit Configuration: Establish if the system design dictates a direct C-face motor/reducer mount layout or an isolated base-mounted separate drive package.
2. Identify Drive Combination Type: Choose the appropriate configuration code based on application requirements, such as a 3040 model for base-mounted shaft-to-shaft clutch setups or a 1020 model for combined clutch/brake motor operations.
3. Verify NEMA Frame Alignment: Match the designated motor or reducer size against the Frame Size Selection chart to secure the proper unit size ranging from size 50 up to size 215.
4. Analyze Thermal Loading: For fast cycle frequencies or large reflected inertia loads, apply the technical heat calculation formula E = 1.7 * WR^2 * (N/100)^2 * F to verify calculated values remain underneath maximum speed-to-heat curve allowances.

HOW TO ORDER

• Specify Base Unit Model: Choose the primary sizing suffix paired with the preferred operational arrangement number, such as UM-210-3040.
• Define System Voltage: Identify the operational direct current criteria to dictate the appropriate 6V, 24V, or 90V DC coil part designation.
• Select Mounting Accessories: Supplement base orders with corresponding optional base kits for freestanding shafts, or motor mounts for supported frame configurations.
• Incorporate Auxiliary Protection: Specify optional NEMA 4 rated conduit boxes or dual-vent cover kits if your environmental placement requires fully sealed, enclosed housings.
