Oil seals, also known as rotary shaft seals, play a crucial role in maintaining the integrity of mechanical systems. They effectively seal grease, fluids, and dirt, ensuring smooth operation by stabilizing the space between stationary and moving components in machinery. The oil seal is a vital element in any mechanical assembly, typically comprising three essential components:
A sealing material (rubber component), robust metal casings, and durable springs. Together, they form a versatile sealing assembly that meets diverse needs.
We offer a wide array of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others.
At Ningbo Zhongmu Rubber Products Co., Ltd, we provide a broad spectrum of superior rubber materials for the creation of oil seals, tailored for various operating conditions. These exceptional rubber materials are designed to withstand diverse chemicals and cope with extreme temperatures, whether blistering hot or freezing cold.
[Oil seal material introduction]
| Ding Rubber (NBR) | Temperature resistance of 100ºC, good oil resistance, wear resistance, anti-aging, good sealing effect. |
| silica gel (VMQ) | Temperature resistance of 200ºC, general oil resistance, high temperature resistance, good waterproof, non-toxic. |
| Fluorogel (FKM) | Temperature resistance of 280ºC, good oil resistance, wear resistance, high pressure resistance, corrosion resistance. |
| ethylene-propylene-diene misch-polymere (EPDM) | Temperature resistance of 150ºC, general oil resistance, corrosion resistance. |
| (PTFE) | Temperature resistance of 280ºC, good oil resistance, wear resistance, high pressure and corrosion resistance. |
| polyurethane (PU) | Temperature resistance of 90ºC, good oil resistance, wear resistance. |
| Single lip structure | Single channel sealing lip for low pressure reciprocating motion (e. g. automotive crankshaft oil seal) |
| Double lip structure | Two upper and lower sealing lips, a main seal (contact shaft), a secondary seal (dust), often used in high pressure environment |
| Composite lip structure | Main lip + dust lip + buffer spring (like type NOK TCV), can withstand both radial and axial forces |
| labyrinth packing | Multi-channel ring groove design to block oil by throttling effect (suitable for high-speed rotating axis) |
| Seal the oil swing ring | Metal ring rotating centrifugal oil swing with shaft (commonly used in gearbox gearbox) |
| Component name | Material selection | function declaration |
| seal(ing)lip | NBR/FKM/PTFE | Main seal surface, the contact shaft forms a dynamic seal |
| spring | Stainless steel / carbon steel | Provide lip pretension to compensate for wear |
| skeleton | PA6/PC | Fixed the sealing lip shape and transfer the mounting stress |
| Dust-proof lips | polyurethane elastomer | Blocking the entry of solid impurities (optional) |
| Self-lubricating coating | plumbago/PTFE | Reduce the friction coefficient and extend the life life |
When installing, consider the rotational speed, temperature, pressure, and medium characteristics of the shaft for optimal performance. Ensure the vertical shaft is properly aligned to prevent tilting and apply grease to the lip for reduced dry grinding.
