Product Description

Frequently Asked Questions

What is a Ruland Manufacturing slit coupling used for?

A Ruland Manufacturing slit coupling connects two shafts in motion-control systems, compensating for minor misalignment while transmitting torque. It is commonly used in encoders, stepper motors, and precision positioning equipment where zero backlash and high torsional stiffness are required.

What are the specifications of the Ruland RLS16-6-4-A slit coupling?

The Ruland RLS16-6-4-A is a long set screw slit coupling with a 3/8 in bore diameter 1 and a 1/4 in bore diameter 2. Its overall length is 1 11/32 in. This model is designed for applications needing a compact, zero-backlash connection between two different shaft sizes.

Where to buy Ruland Manufacturing couplings in worldwide?

3G Electric supplies and delivers Ruland Manufacturing couplings worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order reaches any international destination. Contact us for availability and lead time on the RLS16-6-4-A or other Ruland components.

How to select the right Ruland slit coupling for my application?

To select the correct Ruland slit coupling, match the bore diameters to your shaft sizes and confirm the overall length fits your space. Consider torque requirements and misalignment tolerance. For the RLS16-6-4-A, ensure one shaft is 3/8 in and the other is 1/4 in. Consult Ruland's technical data for load ratings.

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.
