General Information |
N/A 4H multi-disc flange mounted clutches provide big torque in a small package. Available in 7 sizes with static torque up to 10000 lb·in at 80 psi, bores up to 2.375 in. More durable, and higher RPM than the LSCC clutch series. The flange/drive shell of this clutch has no support bearing of its own so is supported by what is being driven or can be secured to the machine frame and used as a brake. Consult Nexen for use in cyclic applications, or use as a brake. Drive shell support is provided by bearing mounted flywheel or Pulley or Sprocket. |
