1. Dimensions The numbers can indicate the dimensions of the seal. For instance, the first number may denote the inner diameter, the second, the outer diameter, and the third could refer to the width or height of the seal. These dimensions are critical for ensuring that the seal fits perfectly within the intended assembly, thereby maximizing effectiveness.

2. Contaminant Protection Grease seals act as a first line of defense against contaminants. Dust, water, and debris can enter the bearing assembly and potentially lead to corrosion, pitting, and other forms of wear. By keeping these contaminants out, grease seals help maintain the integrity of the bearings.

In manufacturing equipment, where heavy machinery is common, the 25% 2035 7 oil seal helps to contain fluids and prevent contaminants from entering systems. This is particularly important in hydraulic applications, where the integrity of the hydraulic fluid must be maintained for effective operation. Similarly, in construction machinery, the seal plays a vital role in ensuring that heavy equipment operates smoothly, reducing maintenance costs due to leaks and failures.
