PRODUCT DESCRIPTION

The Warner Electric 5370-273-236 is a Generation 2 (Gen 2) Smooth-Start™ UniModule, serving as the modernized direct replacement for the legacy 5370-273-157. This pre-assembled clutch/brake package is engineered specifically for applications requiring “soft engagement” to protect sensitive products and mechanical components from the harsh shock of standard engagement.

By utilizing specialized LK friction material, the 5370-273-236 provides controlled, reduced torque. This allows for longer slip times during starts and stops without the significant loss of service life typically associated with standard friction materials.

FEATURES

  • Gen 2 Modernization: Direct replacement for obsolete/legacy models with improved thermal capacity.
  • Smooth Engagement: LK friction material prevents aggressive mechanical shock.
  • Extended Service Life: Engineered to tolerate longer slip times during dynamic cycling.
  • Maintenance Free: Automatically compensates for wear to maintain consistent performance.
  • NEMA Compatible: Easy “bolt-on” installation for standard 56C and 48Y frame sizes.
  • Controllability: Optimized for use with dual-channel adjustable power supplies.

SELECTION PROCEDURE

  1. Application Verification: Confirm the need for soft starts/stops (e.g., bottling lines, light conveyors).
  2. Frame Size Matching: Ensure the motor/reducer uses a NEMA 56C or 48Y frame.
  3. Operating Speed: Confirm the shaft speed is within the 3600 RPM maximum limit.
  4. Torque Verification: Ensure the 10 lb-ft static torque rating meets application requirements.

HOW TO ORDER

  • Specify Model: Order Part Number 5370-273-236 for the Size 50 90V configuration.
  • Select Control: Pair with the CBC-300 (6021-448-009) to independently adjust clutch and brake torque levels.
  • Include Accessories: Order the optional Conduit Box (5370-101-042) for simplified wiring and UL listing compliance.
  • Environmental Protection: If the unit will be exposed to dust or moisture, include a Cover Kit (5370-101-076) to enclose the vented housing.
