Product catalog summary
Service Manual Overview: This document is a service manual for the Friction Torque Limiters Series 300, specifically with Coupling Series 300-05. It provides detailed instructions on adjusting slipping torques for various sizes of torque limiters, along with warranty information and specifications.
Adjustment Procedures:
  • Sizes 10 to 30: Tighten the adjusting nut until no slip is observed under maximum load. Further tighten by 60 degrees to prevent excess slip during start-up.
  • Sizes 40 to 60: Tighten the adjusting nut against the pilot plate and adjust bolts equally until no slip is observed. Further tighten bolts by 60 degrees.
  • Size 70: Different spring assemblies require hand tightening of the nut and equal adjustment of 8 bolts until no slip is observed. Further tighten bolts by 60 degrees.

For all sizes, maximum torque is achieved at approximately 80% spring deflection, and exceeding this can damage the springs.

Specifications:
  • Assembly A: Maximum slipping torque of 3,800 N.m.
  • Assembly B: Maximum slipping torque of 6,800 N.m.
Graphical Data: The document includes torque adjustment graphs for different sizes, illustrating the relationship between the number of rounds and torque in N.m.
Warranty Information: Warner Electric LLC offers a one-year warranty for defects in material or workmanship, applicable to the original purchaser. The warranty covers repair or replacement but excludes damages from alteration, accident, or improper use.
Additional Notes: Dimensions and specifications are subject to change without notice, and certified prints are available upon request.
