High Temperature Resistant Oil Seals FKM SC Type Oil Seal Single Lip Seals For Hydraulic

Working Characteristics

SC-type single-lip oil seal, which falls under the category of rotating oil seals, features a single-lip design. This simple yet efficient structure delivers particularly outstanding sealing performance in dust-free environments. Compared to double-lip oil seals, the absence of an additional dust-proof lip makes the SC-type oil seal more compact in structure, lighter in weight, and more cost-effective. It is an ideal choice for applications where dust protection requirements are low and emphasis is placed on sealing performance and cost-effectiveness.

The internal metal skeleton provides a stable support structure, ensuring that the oil seal does not deform due to external forces during installation and long-term use, maintaining its optimal sealing shape. A self-tightening spiral spring wrapped around the inner side of the lip automatically adjusts the clamping force on the shaft based on its rotational conditions. When the shaft rotates at high speeds, causing vibrations, or when temperature changes cause slight deformation of the shaft, the spring promptly compensates for the gap, maintaining constant sealing pressure between the lip and the shaft, significantly enhancing the reliability and durability of the seal.

The diversity of materials expands the application scope of the SC-type single-lip oil seal. Nitrile rubber, with its excellent oil resistance and wear resistance, is widely used in general industrial applications. In crankshaft seals for automotive engines and shaft seals for transmissions, SC-type oil seals made of nitrile rubber effectively resist engine oil corrosion and maintain stable sealing performance at operating temperatures below 100°C, ensuring the normal operation of the automotive powertrain system.

Fluorocarbon rubber is renowned for its exceptional high-temperature resistance and chemical corrosion resistance. In high-temperature and highly corrosive environments such as aircraft engines and chemical reactors, fluorocarbon SC-type oil seals can withstand temperatures up to 200°C and resist corrosion from strong acids and alkalis, ensuring the safe and stable operation of equipment. Silicone rubber material, due to its non-toxic, odorless, and excellent high and low temperature resistance properties, is widely used in the food and pharmaceutical industries. In the stirring shafts of food processing equipment and the transmission components of pharmaceutical filling equipment, the silicone rubber SC-type oil seal ensures sealing performance without contaminating the product, meeting the industry's strict hygiene standards.
