Couplings

A couplings provides a dependable and versatile solution for connecting shafts in a wide array of general-purpose applications. These couplings are engineered for durability and ease of use, ensuring a secure, efficient means of transmitting torque. Designed to accommodate slight misalignments, they help reduce wear and maintain smooth operation in connected equipment. Ideal for use in motors, pumps, and light machinery. They offer a practical and cost-effective solution. With their robust construction and reliable performance, these couplings are an excellent choice for maintaining equipment performance. 

Couplings Features:

Very High Airflow

PCL 100‑Series couplings have a large nominal bore (10.3 mm) and are designed to deliver high airflow (≈ 117 CFM / 3,313 l/min). This ensures pneumatic tools operate efficiently with minimal pressure drop, even under demanding conditions.

High Working Pressure

These couplings are rated for a maximum working pressure of 14 bar (200 psi), making them suitable for most industrial and workshop compressed air applications. Their robust construction ensures reliable operation under sustained pressure.

Robust and Safe Construction

Built with a hardened steel shoulder and high-quality materials, these couplings prevent accidental disconnection and withstand rigorous job-site use. They also feature a swivel design to reduce hose kinking, extending the life of hoses and connections.

Wide Operating Temperature

PCL couplings are designed to operate reliably across a broad temperature range (–40 °C to +100 °C), allowing safe use in both extreme cold and heat.

FAQs

Are custom couplings more expensive than standard couplings?

No, the engineering process required to create your custom flexure is completely free and is part of our committed service to you. Pricing is a function of the complexity of the design and the material specified.

Do speciality or non-standard couplings take longer to manufacture?

No, just because they are referred to as “non-standard” does not mean that we may not already have these products in our inventory.

What is meant by “single start” and “multiple starts”?

A single start spring is a single continuous coil element that starts at one end and terminates at the other end. This configuration is common to most springs. A “double start” spring has two intertwined continuous coil elements phased 180 degrees apart. In effect, this puts two independent helixes in the same cylindrical plane. Multiple start flexures, such as triple start, etc., are similar extensions of the concept.

What are some of the benefits of multiple start flexures?

Multiple start flexures are beneficial because they not only provide redundant elastic elements should a failure occur, but a failed element (coil) will be physically trapped by the remaining ones.
