About Starflex Couplings

Starflex Couplings

staflexcouplingStarflex has a simple construction of two hubs with one element inside. There are 2 kinds of elements that are different in hardness, selectable according to misalignment and torque response. The material of element is Polyurethane Elastomer, that realized 2 times of torque comparing with our present jaw type coupling. No backlash is possible due to the pre-pressured design of element and hub. The hub is made of aluminum alloy, which has two types of connection, clump type or key type. Starflex passed our Green design criteria and adopts to RoHS instructive.
ALS-R TYPE

Starflex has a simple construction of two hubs with one element inside. ALS-R Type material of element is Polyurethane Elastomer (hardness 97 JIS A), that realized 2 times of torque comparing with our present jaw type coupling. No backlash is possible due to the pre-pressured design of element and hub.

ALS-Y TYPE

Starflex has a simple construction of two hubs with one element inside. ALS-Y Type material of element is Polyurethane Elastomer (hardness 90 JIS A). No backlash is possible due to the pre-pressured design of element and hub.

Normal torque	1.2Nm to 310Nm
bore range	3mm to 60mm
Operational temperature	-30^oC to +80^o

ALS-B Type Starflex has a simple construction of two hubs with one element inside. The material of element is Polyurethane Elastomer (hardness 97 JIS A). ALS-B Type with uncompressed loose fit shape can increase the permissible misalignment by modifying the torqe transmission part to crowning shape.

Normal torque	12.5Nm to 525Nm
bore range	8mm to 60mm
Operational temperature	-30^oC to +80^oC

Exceptional Misalignment Compensation

Starflex Couplings are engineered to accommodate axial, angular, and radial misalignments that commonly occur in drive systems. This versatility helps protect connected equipment from undue stress and prolongs service life, ensuring stable and reliable performance even under fluctuating loads or slight installation inaccuracies.

Designed for Vibration and Shock Absorption

With an elastomeric star insert, Starflex Couplings effectively dampen vibrations and absorb shocks during operation. This feature is crucial for sensitive machinery, providing quieter running and safeguarding components from premature wear in demanding industrial environments.

Maintenance-Free Operation

Unlike many couplings that require regular lubrication, Starflex Couplings operate without the need for ongoing greasing or oiling. The robust star insert and quality surface treatments minimize wear, helping to reduce downtime and maintenance costs in your systems.

FAQs of Starflex Couplings:

Q: How do Starflex Couplings compensate for misalignment in machinery?

A: Starflex Couplings are designed to handle axial, angular, and radial misalignments through their star-shaped elastomeric insert. This flexibility helps to prevent damage caused by shaft misalignment and ensures smoother operation of connected equipment.

Q: What are the main benefits of using Starflex Couplings for power transmission?

A: Starflex Couplings deliver vibration and shock absorption, require no lubrication, and are suitable for high-speed and high-torque applications. Their precision-machined structure and elastomeric insert improve machinery longevity and reduce maintenance requirements.

Q: When should I select a different insert hardness for Starflex Couplings?

A: Standard Starflex inserts are Shore 92A hardness, ideal for most industrial uses. If your application demands specific damping or torque characteristics, alternative hardness levels can be requested to match unique operational requirements.

Q: Where can Starflex Couplings be used effectively?

A: These couplings excel in a variety of settings such as pumps, compressors, fans, and other industrial machines requiring reliable power transmission and vibration control. They are also adaptable for different environmental and load conditions.

Q: What is the installation process for Starflex Couplings?

A: Installation involves aligning the hubs on each shaft, securing with clamping or set screws, and placing the star-shaped insert between them. The bore and diameter are customizable for precise fitting, ensuring secure and efficient connection.

Q: How does the maintenance-free design benefit users?

A: With no requirement for lubrication and robust surface treatments like phosphating or painting, Starflex Couplings significantly cut down routine maintenance, minimizing downtime and reducing overall operating costs for users.
