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 skeletonoil 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 sealwith 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 ordinaryoil 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 |
