TB WOODS FSH Form Flex Couplings
TB Woods FSH Form-Flex couplings connect fully supported shafts that require wider separations. These couplings help to install and maintain the equipment without moving the connected machinery and permit shaft separations ranging from 3 to 12 inches. They are used in centrifugal & screw compre...ssors, reciprocating compressors, fans & blowers, food processing, machine tools, cooling towers and engine & electric motor-driven applications.Read more

FSH Form Flex Couplings
TB Wood's FSH Form-Flex couplings are designed to transmit torque while compensating for angular, parallel and axial misalignments between two connected shafts. These couplings feature a flexible disc to minimise the misalignment errors and offer high torsional stiffness to maintain the structural integrity of the system. Choose from a wide range of these TB Wood's couplings, available in 6 to 12 bolt hole options on Raptor Supplies.
Features
- They feature alloy steel discs, allowing them to withstand heavy loads and harsh operating conditions.
- These couplings consist of no moving parts, eliminating the need for ongoing maintenance and reducing downtime.
- They offer zero backlashes which means that there is minimal or no play between the connected shafts, ensuring precise motion control and accurate positioning where precision is crucial.
- These Form-Flex disc couplings have high torsional stiffness, ensuring efficient power transmission & precise torque transfer and maintaining the integrity of the coupling under load.
Frequently Asked Questions
Can these disc couplings be used for a long period?
Yes, they are designed to withstand continuous operation and perform reliably over an extended period. They reduce the need for frequent replacements and also contributes to cost savings.
How do TB Woods FSH Form-flex couplings accommodate misalignment?
- Disc couplings utilise two flexible discs and a spacer to achieve a double hinge effect, enabling compensation for parallel offset misalignment between shafts.
- In the case of parallel misalignment, both flex discs experience the same angular deflection.
- On the other hand, angular misalignment of either connected shaft results in additional angular deflections that are combined with the angular offset caused by parallel misalignment.
- The overall misalignment angle at the flex disc is the sum of the angular offset due to parallel misalignment and the angular offset resulting from angular misalignment.
- It is crucial to ensure that the total misalignment angle never surpasses the rated misalignment capacity specified for the chosen coupling type.
Are these TB Woods FSH Form-Flex couplings suitable for horizontal and vertical shaft arrangements?
Yes, TB Woods FSH Form-Flex couplings exhibit versatility and can be effectively employed in horizontal and vertical shaft configurations. They possess the capability to accommodate angular, parallel and axial misalignments.
Can TB Woods FSH Form-Flex couplings dampen vibrations in the system?
Yes, TB Woods FSH Form-Flex couplings absorb and mitigate vibrations, leading to a reduction in stress exerted on the connected equipment and an improvement in the overall performance of the system.
