Seven essential OEM spare parts for refrigeration compressors

Refrigeration systems are an essential part of many industrial processes, and they rely heavily on the performance of the compressor. While refrigeration compressors are designed to be durable and long-lasting, regular wear and tear over time can cause their components to break down, leading to a loss in efficiency and eventually system failure.

When that happens, it’s essential to have the right OEM spare parts on hand to get your system back up and running.


Some of the most critical refrigeration compressor components are the shaft seals, cylinder liners, pistons, connecting rods, filters, crankshafts, and O-rings. These parts can wear out due to a variety of factors, such as overuse, temperature fluctuations, or environmental factors like dirt, dust, and moisture.


Shaft seals are an essential component of compressors, as they prevent refrigerant leakage from the compressor shaft. Over time, shaft seals can become worn or damaged, leading to leaks and reduced system efficiency. It’s important to regularly check and replace your shaft seals to avoid potential system failure.


Cylinder liners and pistons work together to compress the refrigerant, so it’s important to ensure they’re in good working condition. Cylinder liners can become worn or damaged due to dirt and debris in the system, while pistons can suffer from overheating and wear. Regularly checking and replacing these components can help keep your system running smoothly.


Connecting rods are critical components that connect the piston to the crankshaft, and they can become worn or damaged over time. Regular maintenance and replacement of connecting rods can help prevent potential system failure.


Filters are used to remove contaminants from the refrigerant but they can become clogged or dirty over time. It’s important to regularly replace your filters to prevent damage to other compressor components, like the cylinder liners and pistons.


Crankshafts are the backbone of the refrigeration compressor. They can become worn or damaged due to temperature fluctuations and other factors. Regular inspection and replacement of crankshafts can help ensure your system operates at peak performance.


Finally, O-rings are used to create a seal between two components in the refrigeration compressor, such as the cylinder liner and the head. They can become brittle over time and lose their elasticity, which can lead to refrigerant leaks. Regular inspection and replacement of O-rings can help prevent leaks and ensure your system runs efficiently.

“Having OEM spare parts on hand for your refrigeration compressor is essential for maintaining the integrity of your system,” says Tristan Buchinhoren, managing director and founder of Spare Exparts. “Regularly inspecting and replacing critical components like shaft seals, cylinder liners, pistons, connecting rods, filters, crankshafts and O-rings can help prevent potential system failure and keep your system running smoothly for years to come.”
