Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING FSR12-5-5-A coupling used for?

The RULAND MANUFACTURING FSR12-5-5-A is a general purpose set screw beam shaft coupling used to connect two shafts in motion control applications. It accommodates up to 3° angular misalignment, making it suitable for precision positioning systems, encoders, and light-duty power transmission where misalignment correction is needed.

What are the specifications of the RULAND MANUFACTURING FSR12-5-5-A coupling?

The RULAND MANUFACTURING FSR12-5-5-A coupling has a 5/16 in bore diameter with same bore dimensions, a round inch-dimensioned design, and no keyway. It is rated for 3° angular misalignment. The manufacturer part number is FSR12-5-5-A, and it is a general purpose set screw beam shaft coupling.

Where to buy the RULAND MANUFACTURING FSR12-5-5-A coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING FSR12-5-5-A coupling to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this motion control coupling.

How to select the right RULAND MANUFACTURING beam coupling for my application?

To select the right RULAND MANUFACTURING beam coupling, match the bore diameter to your shaft size (e.g., 5/16 in for the FSR12-5-5-A), confirm the angular misalignment rating (3°), and decide if a keyway is needed. For inch-dimensioned shafts, this round coupling is a direct fit. Consult a technical specialist for torque and speed requirements.
