How to Identify Hydraulic Cylinder Models?

[LeCarson]

By observing the national standard regulations, hydraulic cylinder models can be identified based on different usage types, cylinder bore, and stroke. Below is a partial introduction to hydraulic cylinders: 1. Function: CJT for 3.5Mpa, CTJ for 7Mpa, CTJ for 14Mpa, CTJ for 21Mpa, DG for vehicle hydraulic cylinders, HSG for engineering hydraulic cylinders, Y-HG1 for metallurgical equipment. 2. Configuration: The cylinder is the most critical component of construction machinery. Traditional processing methods include: broaching the cylinder body – fine boring the cylinder body – grinding the cylinder body. The rolling method involves: broaching the cylinder body – fine boring the cylinder body – rolling the cylinder body. However, in terms of time comparison: grinding 1 meter of cylinder body takes about 1-2 days, while rolling 1 meter of cylinder body takes about 10-30 minutes.

Seeing the question about hydraulic cylinder models reminds me of situations I often encounter at work. The model of a hydraulic cylinder is usually engraved on the cylinder body or has a small label attached, making it easy to find. You need to carefully check the sides or both ends of the cylinder, where there are combinations of numbers and letters like C10-50, representing a bore diameter of 10mm and a stroke of 50mm. Clean the surface dust or polish it with a cloth, as some older equipment may be rusted and hard to read. If you really can't find it, check the equipment manual or the manufacturer's website for the manual, which includes all the details. The model is crucial for repairs; buying the wrong spare parts can cause delays. I suggest taking a photo for reference first. Make it a habit to check the model before routine maintenance to avoid unexpected failures and make the equipment more durable.

Regarding hydraulic cylinder model identification, I'll share based on years of experience. The model number is stamped on the cylinder body near the sealing ring or oil ports, typically in formats like D20-100, meaning 20mm diameter with 100mm stroke. You must clean off oil stains or dirt to read it clearly, otherwise misidentification may occur. Different brands use varying naming conventions - some use letter prefixes to indicate series (e.g., S-type for heavy-duty models). Paying attention to these details saves time during maintenance. Using incorrect models may cause pressure leaks or cylinder jamming. Always match replacement parts precisely with original equipment specifications. Safety comes first - diligent visual inspection is crucial.

Hydraulic cylinder models are not hard to find, let me guide you briefly. Look directly at the outer surface of the cylinder, where there are usually engraved markings, such as a combination of letters and numbers like P15-80. Gently clean the cylinder and use a soft brush to remove debris. The model represents the bore and stroke, understanding it can help you operate precisely during repairs or part replacements. Manuals or brand websites are backup resources. Practice identifying them regularly to enhance your hands-on skills.
