Type Code number Main features Usage Dielectric pressure resistance Maximum line speed
Simple single lipped B It is commonly used for high and low speed rotating shafts and reciproing movement to seal mineral, oil and water. Ordinary oil seal, in the of less dust and impurities, the use of medium pressure, the reciproing speed of <0.1m/s. <0.05MPa 15m/s
Regular lip FB In addition to the characteristics of the above S type oil seal, dust can be prevented. Ordinary oil seal, with dustproof lips, dustproof, resistant to medium pressure <0.05MPa 15m/s
No spring type BV Spring free single lip type inner frame type rubber oil seal. Generally applicable to low-speed conditions, the sealing medium for the lubriion of ester. <0.05MPa 6m/s
Outer skeleton, single lip W With the spring single lip exposed skeleton rubber oil seal, waist thin, follow good, good rigidity. Ordinary oil seal, used in of less dust and impurities <0.05MPa 15m/s

Because of the backflow effect, the radial force is smaller than that of the ordinary oil seal, thereby reducing wear and heat build-up and improving service life <0.05MPa 20m/s
Pressure type NY The lip is short, stubby waist, with pressure, work pressure is less than 3MPa. The shaft end oil seal for high pressure pump, general PV value is less than or equal to 8 ≤3MPa 15m/s
