Hebei Hankai 35 47 7 oil seal

Some applications require specialized or customized hydraulic seal kits. These kits may be designed for unique machinery or extreme operating conditions. Customization often means higher costs due to the specific engineering, research, and development involved. If your application has unique requirements, it's essential to factor in this cost when budgeting for hydraulic seals.

2. Seal Design Oil seals come in various designs, such as lip seals, O-rings, and composite seals. The complexity of the design can impact production costs and, subsequently, the price. For example, a multi-lip seal may offer better sealing capabilities than a simple O-ring, but it will also require more intricate manufacturing processes, leading to higher prices.

Conclusion

The nomenclature 30x42x7 describes the oil seal's three critical dimensions the inner diameter (ID), outer diameter (OD), and width (W). Specifically, this oil seal features an inner diameter of 30 mm, an outer diameter of 42 mm, and a width of 7 mm. These measurements indicate that it is designed to fit into a specific space within a machine, preventing the leakage of fluids, particularly oil, from critical components like shafts and housings.

2. Inspect Parts Examine the internal components for any signs of excessive wear or damage. Identifying all parts needing replacement will ensure a thorough rebuild.
