1.Firstly, it is a single-piece, vulcanized construction that fuses a metal framework with a rubber one, so that the latter has a stiff support to prevent it from sagging.
2. The metal reinforced rubber strip is adjustable in hardness and can be made of a range of rubber types such as NBR, EPDM, and FKM.
3. It can be resistant to mineral oil, water, steam, weak acids, alkalis, and several other chemical media depending on the material, temperature range would be from -40°C to 180°C.
Standard solid rubber seals or split-type composite washers are quite likely to experience a steep drop in sealing preload after several hundred hours of equipment operation because of rubber creep relaxation and absence of a strong structural support. This in turn causes the leaking of the media, e.g. oil coming out through the gap between the seal frame and the mounting hole, and that results in environmental pollution and unexpected machine downtime.
Professional Steel Skeleton Rubber Seal Solutions.
Integrally vulcanized steel skeleton rubber seals combine a metal skeleton with rubber in one single manufacturing process. Having a metal support frame inside, they not only possess very high structural rigidity and resistance to deformation but also maintain precise positioning and excellent coaxiality.
With metal which is stable and rubber which has excellent sealing properties, these seals may be used as universal standard components to carry out permanent installation, prevention of dust and leakage as well as precise sealing in other mechanical equipment.

Our Main Types of Skeleton Oil Seals Include:
·Skeleton oil seals: Oil and water-resistant seals for rotating shafts.
·Skeleton flange gaskets: Static face seals for equipment.
·Embedded skeleton flat washers: Seals for vibration damping, compression resistance, and positioning.
·Bearing dust-proof skeleton rings.
·Motor end-cap seals.
Product Advantages:
1. Dimensional stability and precise, secure installation.
Our metal reinforced rubber seals incorporate a rigid metal skeleton inside (which can be cold-rolled steel, galvanized steel, or stainless steel, and the thickness of the metal can be adjusted from 0.5 to 2.0 mm). This structure greatly reduces the possibility of deformation due to pressure or incorrect installation. The skeleton also acts as a guide for the exact placement of the seal, ensuring a tight fit, making the assembly easier, and stopping the seal from falling off or getting loose.
2. Reliable sealing and multi-layered protection.
The rubber body and metal skeleton are inseparably combined by vulcanization, giving a perfect bonding that does not even come close to any crack or delamination. After the installation, the rubber lip lies closely to the surface, thereby preventing the entry of dust, moisture, oils, and other contaminants. A good installation results in a waterproof, oil-proof, and dust-proof sealing which makes it perfect for the cleanest environments like hydraulics, vehicles, and electric motors.
3. Compression and wear resistance with excellent load-bearing and impact performance.
Using a combination of the steel skeleton's structural support and the rubber's flexibility, our rotary shaft seals are able to perform under difficult operating conditions, for example, vibration and heavy loads. The rubber part has a tensile strength of 10–20 MPa and elongation of 200%–450%; together with a Shore A hardness of 65–95, this guarantees the sealing lip will not be damaged even after being compressed repeatedly at high pressure, thereby greatly reducing the possibility of wear and cracks.
4. Enhanced long-term operational stability.
The rubber formulations that we make use of have been calibrated for excellent aging and impact resistance among many other properties. Despite a compression set control of about 15-30%, these rubbers stay highly resilient during long-term usage. The material type/metals determine resistances to the presence of mineral oils, water, steam, weak acids and alkalis, certain chemical media, and various industrial fluids. The operating temperature range of the resulting rubber is -40°C to 180°C.
Product Applications:
Taking advantage of these rotary shaft seals features with the media-resistance attributes of different materials, they can be applied in the commercial vehicle chassis, industrial motors and fans, construction machinery, and precision instruments. Some of the main uses are automotive chassis components, motors and fans, gear reducers, water and oil pumps, construction machinery, household appliances, valves and piping, instrumentation, agricultural machinery, and sealing, positioning, and dust protection for hydraulic equipment housings.

FAQ:
1. How is the reliability of the bond in a skeleton oil seal ensured throughout its service life?
We utilize a specialized vulcanization process for integrated molding, resulting in high bond strength that passes rigorous peel tests.
2. How is the skeleton protected against corrosion in environments involving highly corrosive substances or special media?
We can choose stainless steel skeletons suitable for the type of operating medium or separately conduct anti-corrosion surface treatment of cold-rolled or galvanized steel sheets, so that the second protection layer will totally exclude the risk of skeleton corrosion.
