Wipers, or scraper seals, are designed to keep contaminants out of the cylinder while the piston rod extends and retracts. The size of the wiper should match the rod diameter to provide effective cleaning action without causing damage The size of the wiper should match the rod diameter to provide effective cleaning action without causing damage

hydraulic cylinder seal kits by size. Guide rings, also known as wear rings, aid in aligning the piston rod and reducing friction; their size should be compatible with both the rod and the cylinder bore.


The sealing lip is designed to conform to the shaft, creating a tight barrier that minimizes fluid escape
. Depending on the application, rotary shaft seals can be designed for various shaft diameters and operating conditions, including temperature extremes and high pressures.Oil seals come in various designs depending on the specific requirements of the machinery. The 20x30x7 oil seal, for example, is a standard radial shaft seal that is installed along the shaft to prevent oil from leaking out or contaminants from entering the machinery. This type of seal is commonly used in engines, gearboxes, and other rotating equipment where the sealing of fluids is essential.
On the other hand, the number 2028 paints a different picture. In this case, it could be interpreted as a reference to a specific bearing series or size. For instance, in the standard ISO system, '63' signifies the series, and '28' would denote the bore diameter For instance, in the standard ISO system, '63' signifies the series, and '28' would denote the bore diameter

63 28 bearing. The 6328 bearing would have a bore diameter of 28mm, with the '63' series typically indicating deep groove ball bearings, which are widely used due to their versatility and ability to handle both radial and axial loads.
