Product Description

The RULAND MANUFACTURING Long Set Screw Slit Coupling (MPN RLS8-4-4-A) is a 1/4 in bore diameter 1 and 1/4 in bore diameter 2 coupling with a 25/32 in overall length, in inch dimensions. This slit coupling is designed for motion control applications requiring zero backlash and high torsional stiffness.

Supplied to the Philippines — compatible with 60 Hz installations. DHL Express delivery to Manila, Quezon City, Cebu, customs and duties handled door-to-door.

Frequently Asked Questions

What is a RULAND MANUFACTURING Slit Coupling used for?

A RULAND MANUFACTURING Slit Coupling, such as the RLS8-4-4-A, is used to connect two shafts in motion-control systems. It compensates for minor misalignment while transmitting torque. Common applications include encoders, stepper motors, and linear actuators in industrial automation and precision machinery.

What are the specifications of the RULAND MANUFACTURING RLS8-4-4-A Slit Coupling?

The RULAND MANUFACTURING RLS8-4-4-A is a long set screw slit coupling with a 1/4 in bore diameter on both ends and a 25/32 in overall length. It is an inch-series component designed for precise shaft connections in motion-control applications. The part number is RLS8-4-4-A.

Where to buy RULAND MANUFACTURING couplings in worldwide?

You can source RULAND MANUFACTURING couplings, including the RLS8-4-4-A, through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to worldwide locations. Contact 3G Electric for availability and lead time.

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

To select the correct RULAND MANUFACTURING slit coupling, match the bore diameters to your shaft sizes and ensure the overall length fits your space constraints. Consider torque requirements and misalignment tolerance. For the RLS8-4-4-A, both bores are 1/4 in. Consult RULAND's technical data for load ratings.

Used in

Common applications for RULAND MANUFACTURING

Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.

CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.

Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.

Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.

Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.

Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
