Propulsion Couplings

HTB Couplings

The Renold HTB coupling offers protection against severe shock loads. They’re designed for bell housing applications and are intrinsically failsafe. These couplings can handle temperatures up to 400° F (200° C).

Torque range: 885 to 29,500 lb-ft (1.2 to 40 kNm)
Typical applications: Marine propulsion, compressors, generator sets, pumps, rail traction

Periflex Couplings

Periflex couplings from Stromag are flexible rubber couplings for use with internal combustion engines. The Periflex VN is flanged to mount directly to standard flywheels. The Periflex CS is designed to connect an engine flywheel to a cardan shaft flange.

Torque range: 18 to 46,466 lb-ft (25 to 63,000 Nm)
Typical applications: Steel mills, cranes, conveyors, mining, paper machinery, shipbuilding, construction, PTO’s

Rato Coupling

American Vulkan Rato couplings are torsionally flexible and compensate for radial, axial, and angular misalignment. They can be used on both flexibly and rigidly mounted engines. Couplings are designed for maximum heat dissipation and long life.

Torque range: 5,900 to 5,900,000 lb-ft (8 to 800 kNm)
Typical applications: Marine propulsion, auxiliary drives, generators

Vulastik Coupling

American Vulkan Vulastik L couplings use an extremely compact design for more efficient engines with high power density. Styles are available which allow the element to be replaced without moving the adjacent machinery.

Torque range: 383 to 38,353 lb-ft (0.52 to 52 kNm)
Typical applications: Marine propulsion, auxiliary drives, generators
