Common types of oil seals
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 reciprocating movement to seal mineral, oil and water. Ordinary oil seal, in the case of less dust and impurities, the use of medium pressure, the reciprocating 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 lubrication 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 case of less dust and impurities <0.05MPa 15m/s
Outer skeleton, double lips FW With the lips of the lips exposed, skeleton rubberoil seal, waist thin, followed by good, high stiffness, good coaxial. Ordinary oil seal, with dustproof lips, dustproof, resistant to medium pressure <0.05 <0.05MPa 15m/s
Fabricated single lipped Z From the inside and outside the outer skeleton oil seal skeleton assembly into piping and installation of high precision, fast heat dissipation, heavy load characteristics. Suitable for heavy load under high temperature and high speed condition <0.05MPa 15m/s
Fabricated double lipped FZ The assembled external skeleton oil seal with side lip has the characteristics of dust resistance, high installation accuracy, fast heat dissipation and heavy load characteristics. Apply to high temperature, high speed, heavy load under dust condition ≤0.05MPa 15m/s
Unidirectional reflux type Dextral SR,Levo DL A diagonal bar with angle in lip air measurement system using fluid mechanics principle, produces pump function, with reflux effect. 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
