PRODUCT DESCRIPTION
The Warner Electric EP Series Electro Pack units are rugged, pre-assembled clutch and brake combinations housed in an enclosed, foot-mounted casting. They are factory aligned and engineered to mate easily with industry-standard motors and reducers using V-belts, pulleys, chains, sprockets, inline couplings, or timing belt drives.
Because over 20 major components come pre-engineered and pre-assembled straight from the box, the Electro Pack eliminates complex field alignment tasks, drastically reducing installation downtime.
FEATURES
- Bolt-it-down and wire-it-up structure makes it instantly ready to go.
- Maintenance free design that never requires manual internal lubrication.
- Self-adjusting friction faces automatically compensate for wear to provide consistent cycle-to-cycle performance.
- Heavy duty bearings are factory pre-aligned to ensure maximum mechanical runtime.
- Certified compliance built to satisfy industrial codes and holds official UL Listing status.
SELECTION PROCEDURE
- Step 1: Determine Shaft Velocity—Identify the exact operating speed (RPM) at the shaft location where the Electro Pack will be installed.
- Step 2: Intersect Horsepower and Speed—Cross-reference your input motor horsepower against the shaft speed on the catalog grid matrix.
- Step 3: Locate Model Fitment—Find the intersection point within the shaded regions to confirm that the 270 lb-in static torque capacity of the EP-400 size satisfies your load criteria.
HOW TO ORDER
- Specify Model Configuration: Reference part number 5131-273-031 to secure this standard 270 lb-in capacity framework.
- Verify Voltage and Suffix: Confirm your field control lines match the 90V DC coil arrangement to prevent switching delays.
- Low-Speed Warning: For continuous profiling operations running below 100 RPM, please contact Warner Electric Application Support for technical assistance.
