BOSTON GEAR Coupling Rubber Insert


Boston Gear coupling rubber inserts are flexible components used to connect shafts or parts in the manufacturing, automotive and aerospace industries. They compensate for misalignment between shafts, dampen vibrations and reduce shocks. Moreover, they ensure precise machinery alignment, reducin...g wear and maintenance costs. Also, they absorb engine vibrations for improved overall passenger comfort. Read more

Features

  • Boston Gear coupling inserts are available in oil-resistant synthetic rubber constructions for noise-less operations.
  • They can handle up to 2500 lb-inch torque.
  • These coupling rubber inserts can handle both extremely low temperatures (as low as -32 degrees F) and extremely high temperatures (as high as 300 degrees F).

Frequently Asked Questions

How do coupling inserts compensate for misalignment?

Their rubber construction allows them to flex and deform slightly to accommodate angular, parallel or axial misalignment between connected shafts.

Do Boston Gear coupling inserts affect torque transmission?

No, they reduce vibrations without compromising with transmission efficiency.

What factors should I consider when choosing the best coupling insert for my application?

The choice depends on factors like torque requirements, misalignment tolerance and operating conditions.

Why should I choose coupling rubber inserts over rigid couplings?

Coupling inserts offer flexibility, misalignment compensation, vibration reduction and shock absorption, which rigid couplings cannot provide.
