About Metric Shaft Seals

Metric shaft seals are sized according to the metric system and are typically used in applications where metric sized shafts and housings are used. It usually consists of a sealing element, a rubber housing and a spring. The sealing element is usually made of elastic materials such as rubber or silicone and provides a flexible seal between the shaft and housing. The inner metal provides structural support to the seal, while the spring helps maintain contact between the seal element and the shaft.

特徴

1. The sealing effect is stable and reliable. Since the contact pressure between the sealing ring and the shaft is large enough, it is difficult for lubricating oil or liquid to penetrate from the sealing interface into the external environment. At the same time, the shaft seal can also effectively prevent external impurities from entering the interior of the mechanical equipment and avoid affecting the normal operation of the equipment.

2. Long service life and low maintenance cost. Sealing rings are usually made of wear-resistant rubber or plastic materials, which can resist friction and corrosion and have a long service life. Moreover, the installation and maintenance of shaft seals are relatively simple, requiring only regular cleaning and lubrication, and do not require frequent replacement or repair.

3. The surface quality of the shaft is required to be high. If there are obvious wear or pits on the shaft surface, the sealing effect will be reduced.

4. The use effect in high-speed rotation or high-temperature environment may be affected, and some special measures need to be taken to improve the sealing performance.

アプリケーション・シナリオ

The application scenarios of metric shaft seals include but are not limited to the following situations:

1. Motor: The motor is one of the common mechanical systems. Metric shaft seals can be used to seal the rotating shaft of the motor to prevent internal oil leakage and external contaminants from entering.

2. Pump: A pump is a device used to transmit liquid or gas. Metric shaft seals can be used to seal the rotating shaft of the pump to prevent internal oil leakage and external contaminants from entering.

3. Bearings: Bearings are components used in mechanical systems to support and lubricate rotating shafts. Metric rubber shaft seals can be used to seal the rotating shafts of bearings to prevent internal oil leakage and external contaminants from entering.

4. Gearbox: The gearbox is a component in the mechanical system used to change the speed and direction. The shaft seal can be used to seal the rotating shaft of the gearbox to prevent internal oil leakage and external pollutants from entering.

5. Reducer: The reducer is a common transmission equipment that can reduce the speed of the motor and increase the torque. The shaft seal can be used to seal the rotating shaft of the reducer to prevent internal lubricating oil from leaking and external contaminants from entering. .

6. Pulley: The pulley is a device used to transmit power and motion. The rubber shaft seal can be used to seal the rotating shaft of the pulley to prevent internal oil leakage and external contaminants from entering.

7. Screw conveyor: The screw conveyor is a device used to transport materials. The rubber shaft seal can be used to seal the rotating shaft of the screw conveyor to prevent internal lubricating oil from leaking and external pollutants from entering.

8. Agitator: The agitator is a device used to mix liquids. Metric rubber shaft seals can be used to seal the rotating shaft of the agitator to prevent internal lubricating oil from leaking and external contaminants from entering.

製造工程

1. Raw material preparation: Select rubber or other elastic materials that meet the requirements as raw materials for sealing elements.

2. Mold making: Make the corresponding mold according to the required metric shaft seals size and specifications.

3. Vulcanization molding: Put the raw materials into the mold and vulcanize them under certain temperature, pressure and time conditions to turn the raw materials into sealing elements with the required shape and size.

4. Assembly: Assemble the finished sealing element, rubber shell and spring as required to ensure that the various parts fit closely to form a complete metric shaft seal.

5. Inspection: Conduct quality inspection on the shaft seal to ensure that its size, appearance, performance, etc. meet the specified requirements.

6. Packaging: Pack the inspected metric shaft seals to prevent damage or contamination during transportation and storage.

During the production process, we strictly pay attention to controlling the quality of raw materials, vulcanization molding process parameters and assembly accuracy to ensure that the manufactured metric shaft seals have good sealing performance and service life. At the same time, the production process is regularly inspected and improved to improve production efficiency and product quality.
