Base Seals are an important component used to seal machines and equipment. They are usually used to prevent liquid or gas leaks and protect machines and equipment from dust, pollutants, and other external elements. Base Seals mainly include rubber seals, oil seals, mechanical seals, O-rings, U-rings, V-rings, X-rings, and other types.
Rubber seals are a type of seal widely used in various machines and equipment. They are usually made of rubber materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Rubber seals are mainly used to seal liquids or gases in machinery and equipment, such as automotive engines, water pumps, pipelines, fans, refrigeration equipment, etc.
Oil seal is a type of seal specifically used to seal lubricating oil. They are usually made of rubber and metal materials and have characteristics such as wear resistance, corrosion resistance, and high temperature resistance. Oil seals are mainly used in equipment such as automotive engines, industrial machinery, water pumps, and hydraulic systems to prevent lubricant leakage.
Mechanical seals are advanced seals used to seal machines and equipment. They are usually made of metal and ceramic materials and have characteristics such as wear resistance, corrosion resistance, high temperature resistance, and low temperature resistance. Mechanical seals are mainly used in high-speed rotating equipment, such as centrifugal pumps, compressors, fans, centrifugal separators, etc.
O-ring is a common sealing element, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. O-ring is mainly used in fields such as automobiles, machinery, and electronic equipment.
A U-shaped ring is a sealing element with a U-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. U-rings are mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.
A V-ring is a sealing element with a V-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. V-rings are mainly used in fields such as automobiles, industrial machinery, and hydraulic systems.
7. X-shaped ring
An X-ring is a sealing element with an X-shaped cross-section, usually made of rubber material. They have good sealing performance and elasticity, and can be used to seal various liquids and gases. The X-ring is mainly used in hydraulic systems, pneumatic systems, automotive braking systems, and other fields.

Thrust bearings are commonly used in mechanical systems to support axial loads. They come in various types, including four-point contact ball bearings, single or double row angular contact ball bearings, two-way thrust tapered roller bearings, and cylindrical roller bearings. Some advanced designs also include brake roller radial bearings.
When using four-point contact ball bearings or single/double row angular contact ball bearings as thrust bearings, it is important to note that they are not designed for radial loads. Therefore, the inner bore of the bearing housing must be carefully matched with the corresponding parts of the bearing. The diameter should be slightly larger than the bearing's inner diameter—typically about 0.5 mm more, or less than 0.5 mm if the roller diameter is smaller.
For four-point contact ball bearings, it’s crucial not to interchange the same type of rings during installation, as this could alter the factory-set axial clearance. Similarly, when dealing with two-way thrust tapered or cylindrical roller bearings, the spacer rings must not be swapped, as this can also affect the axial clearance and performance.
When installing the inner ring of a thrust bearing, it’s necessary to press the end device firmly into place. The axial direction must be locked to prevent any relative movement on the roll neck, which could lead to wear or burning of the mating surface.
In the case of brake roller bearings, axial positioning is achieved through two bearing housings, and the axial clearance is adjusted accordingly. During installation, the inner and outer rings of the bearing must be tightly seated against the main bearing’s corresponding rings. When fixing the frame to the two bearing housings, care must be taken to eliminate any axial movement of the housing as it is inserted into the frame.
