Diaphragm Coupling in Turbo Machinery Market Report 2026

The diaphragm coupling in turbo machinery market size has grown strongly in recent years. It will grow from $4.97 billion in 2025 to $5.24 billion in 2026 at a compound annual growth rate (CAGR) of 5.5%. The growth in the historic period can be attributed to expansion of power generation infrastructure, growth in oil and gas processing facilities, increasing use of turbo compressors, availability of high-strength diaphragm materials, rising focus on equipment reliability.

The diaphragm coupling in turbo machinery market size is expected to see strong growth in the next few years. It will grow to $6.68 billion in 2030 at a compound annual growth rate (CAGR) of 6.3%. The growth in the forecast period can be attributed to increasing investments in energy infrastructure modernization, rising adoption of high-efficiency turbo machinery, expansion of chemical processing capacity, growing demand for low-maintenance couplings, increasing focus on predictive maintenance. Major trends in the forecast period include increasing use in high-speed turbo machinery, rising demand for high-torque transmission solutions, growing adoption in power generation systems, expansion of custom engineered couplings, enhanced focus on vibration control.

The increasing focus on renewable energy integration is expected to contribute to the growth of diaphragm couplings in the turbo machinery market. Renewable energy integration involves the incorporation of sources such as wind, solar, geothermal, and hydroelectric power into the existing electric grid. Diaphragm couplings emerge as a favorable choice for renewable energy applications, including solar and wind power, owing to their features such as low backlash, low vibration transmission, high torque capacity, and sustainability benefits. According to the Energy Information Administration, it is anticipated that 16% of total energy generation in 2023 will come from renewable sources such as wind and solar, up from 14% in 2022. The increasing focus on renewable energy integration is thus driving the growth of diaphragm couplings in the turbo machinery market.

Product innovation is a significant trend gaining traction in the diaphragm coupling segment of the turbomachinery market. Leading companies in this sector are creating innovative products to maintain their competitive edge. For example, in April 2024, SKF, a Sweden-based company, launched a series of diaphragm couplings designed to offer cost-effective, lubrication-free operation for high-torque applications with medium torsional stiffness. These couplings are available in various configurations, including single and double disc designs, and can be installed in both horizontal and vertical orientations, supporting load capacities of up to 178 kNm. Made with all-steel mechanical components, SKF diaphragm couplings ensure reliable performance and are particularly suited for high-speed applications due to their two-plane dynamic balance.

In April 2023, Regal Rexnord Corporation, a US-based manufacturer specializing in power transmission components and electric motors, acquired Altra Industrial Motion Corp. for an undisclosed amount. This acquisition is positioned to broaden, diversify, and enhance Regal Rexnord Corporation's product portfolio. The collaboration between the two companies aims to improve the existing automation product portfolio and provide high-value offerings to customers. Altra Industrial Motion Corp., the acquired entity, is a US-based manufacturer specializing in diaphragm couplings, brakes, clutches, and other power transmission products.
