Product catalog summary
Overview: The EC25 Long-Life (EC25LL) is an electromechanical wrap spring clutch designed for high-hour and high-revolution applications, offering up to 80 million bearing revolutions. It provides high torque capacity and performance at a competitive price, with minimal slip during engagement and instant disengagement.
Design Characteristics:
  • Technology: Electromechanical wrap spring clutch.
  • Low Wattage: Requires only 2.5 watts for engagement.
  • High Torque, Small Size: Delivers 25 lb-in (2.83 N-m) of load over 1 million actuations, with dimensions of approximately 1.2 inches in diameter and 1 inch in shaft length.
  • Rapid Acceleration: Accelerates loads from zero to full speed in less than 3 milliseconds.
  • Consistent Performance: Virtually no slippage during engagement and almost instantaneous disengagement.
  • Power Source: Operates on filtered or unfiltered DC power, with filtered power recommended for high-speed applications.
Application Considerations:
  • Single Direction: Provides torque only in the direction of wrap-down, allowing for overrunning.
  • Relative High Shock: Rapid acceleration may require a slip device or coupler as a shock absorber in some applications.
  • Engagement Relative to Speed: Engagement relies on relative motion between input and output; slower speeds result in longer engagement times.
Operating Parameters:
  • Optimal performance within 0°- 60° C (32°-140° F).
  • Typical operating speeds of 100-800 rpm, with a maximum of 1400 rpm.
  • Minimum load friction torque of 6 oz-in (0.05 N-m) plus customer input bearing torque.
Available Options:
  • Direction: CW or CCW.
  • Bore: 1/4 inch or 6mm.
  • Shaft: Cross Pin Only.
  • Voltage: 12 VDC or 24 VDC.
  • Electrical Connection: Molded Connector or 8" Leaded Coil.
Applications: Suitable for paper feed systems, copiers/printers, finishing equipment, collators/sorters, mailing equipment, ticket and receipt dispensers, revolving media displays, and packaging equipment.

Clutch ::  EC25LL -1

Operating Parameters Technology Single Direction Engagement Relative to Speed Relative High Shock EC25 Long-Life performance is best within the following conditions: 0հ- 60C (32а-140F). Е100-800 rpm typical, 1400 rpm max. Minimum load friction torque 6 oz-in (0.05N-m) plus customer input bearing torque. Electromechanical wrap spring clutch. Wrap spring clutches provide torque only in the direction in which they wrap down. This allows for overrunning. The EC25 Long-Life relies on relative motion between the input and output for engagement. Thus, the slower the speed, the longer the time until engagement. Due to the EC25LL's rapid acceleration, system inertia effects can be significant. In some applications a slip device or coupler may be used as a shock absorber. Low Wattage Rapid Acceleration High Torque, Small Package Size Consistent Performance Power Source The EC25LL requires only 2.5 watts of power for engagement. After spring wrap-down, the EC25LL will accelerate loads from zero to full speed in less than 3 milliseconds. The EC25LL provides 25 lb-in (2.83 N-m) oftotal load over a life of 1 million actuationswith an outside diameter of about 1.2 inches (30mm), and a shaft length of about 1 inch (27mm). It also provides approximately 60 million bearing revolutions for typical applications Ֆ 2 to 10 times the bearing life of standard EC25's. Engagement is made with virtually no slippage and disengagement is almost instantaneous. All Reell clutches operate on either filtered or unfiltered dc power.The use of filtered power is recommended for better life at high speed. Innovative Torque Solutionswww.reell.com >
