Ruland 5 45 45 Flexible Coupling PCMR25-10-10-SS

Ruland PCMR25-10-10-SS Flexible Beam Coupling

The Ruland PCMR25-10-10-SS is a precision-engineered flexible beam coupling designed to connect two shafts while accommodating misalignments and transmitting torque efficiently. Crafted from a single piece of 303 stainless steel, this coupling offers exceptional strength and durability, making it suitable for a wide range of industrial applications.

Key Features

• Material: Constructed from 303 stainless steel, providing high corrosion resistance and longevity.
• Bore Size: Equipped with dual 10mm bores, ensuring a secure fit for shafts of corresponding dimensions.
• Dimensions: Features an outside diameter of 25.4mm and a length of 31.8mm, offering a compact design without compromising performance.
• Torque Capacity: Capable of handling a static torque of 4.63 Nm, suitable for various power transmission requirements.
• Zero-Backlash Design: Ensures precise motion control by eliminating play between connected shafts.
• Balanced Construction: Minimizes vibration during high-speed operations, supporting speeds up to 6,000 RPM.
• Compliance: Meets RoHS3 and REACH standards, reflecting a commitment to environmental and safety regulations.

Applications

This flexible beam coupling is ideal for applications requiring precise motion control and the ability to accommodate misalignments, such as:

• Servo and stepper motor drives
• Encoders
• Lead screws
• Pumps
• Conveyors

Installation Guidelines

1. Align the coupling bores with the shafts to be connected, ensuring misalignment parameters are within the coupling’s limits.
2. Tighten the M4 screws on one hub to the recommended seating torque of 4.6 Nm using a 3.0 mm hex torque wrench.
3. Rotate the coupling by hand to allow it to reach its free length before tightening the screws on the second hub.
4. Ensure the coupling remains axially relaxed and the misalignment angle is centered along its length during installation.
5. Shafts may extend into the relieved portion of the bore, provided they do not exceed the maximum shaft penetration length of 14.7 mm.

The Ruland PCMR25-10-10-SS flexible beam coupling combines precision, durability, and ease of installation, making it a reliable choice for various mechanical systems requiring accurate torque transmission and misalignment accommodation.
