Simple single lippedBIt 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.<0.05MPa15m/s
Regular lipFBIn 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<0.05MPa15m/s
No spring typeBVSpring free single lip type inner frame type rubber oil seal.Generally applicable to low-speed conditions, the sealing medium for the lubrication of ester.<0.05MPa6m/s
Outer skeleton, single lipWWith 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<0.05MPa15m/s
Outer skeleton, double lipsFWWith 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<0.05MPa15m/s
Fabricated single lippedZFrom 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<0.05MPa15m/s
Fabricated double lippedFZThe 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≤0.05MPa15m/s
Unidirectional reflux typeDextral SR,Levo DLA 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<0.05MPa20m/s
Pressure typeNYThe 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≤3MPa15m/s
1.Unusually high wear resistance.
2.High resistance qgainest extrusion.
3.Perfect sealing performance.
5.Good temperature tolerance.
6.lips prevent dust pollution.
(1)Packed by plastic bags,put into Plywood cases that don't need fumigation. Other packing is customized according to client's requirements.
(2)PTFE surface treated should be kept in dark place, can not be damaged.
