- The inclusion of 7% steel, often in the form of a metallic insert or spring, further fortifies the oil seal's performance
20 30 7 oil seal. Steel provides the necessary rigidity to withstand mechanical stress and maintain the seal's position within the machinery. It aids in preventing the seal from extrusion, particularly in scenarios where there is significant pressure acting against it.
These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
Table 1: The order of priority for selecting oil seals
Are you looking to keep your machinery free from any unwanted leakages but aren’t sure which rotary shaft seal is right for your needs? This guide will provide you with everything you need to know in order to select the right one for your application.



Indeed, when installing this oil seal, the oil sump must be installed using silicone seal. Removal of the old seal and oil sump is necessary, otherwise the oil seal cannot be fitted properly either. If these steps are not followed, leakage is inevitable.

Description
Heavy Duty Wheel Seals and Agricultural Equipment Seals can be divided into AP type, CRS type and ST type. Mainly be used in heavy pollution of agricultural machinery, construction machinery, mining equipment and trucks, buses and other environments. Compared to TC type, with special internal lubrication design, making it closed to the rotary shaft seal and bearing assembly which prevent external dirt effectively; a specially designed multi-lip inside the seal, makes it to achieve the function. Multiple external sealing lip design effectively prevents outside dirt and grease leakage immersion; the internal high-quality grease (butter) prevents muddy and water immersion.

Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
