Oil Seal Type And Purpose (1)

Regular Single Lip B (SC)
Generally used for sealing mineral oil and water in high and low speed rotating shafts and reciprocating motion.
Ordinary oil seals are used when there is relatively little dust and impurities, with a resistance to medium pressure of<0.05MPa, a maximum linear speed of 15m/s, and a reciprocating speed of<0.1m/s [3].
Regular Double Lip FB (TC)
In addition to the usage features of the S-shaped oil seal mentioned above, it can also prevent dust.
Ordinary oil seal with dust-proof lip can prevent dust and withstand medium pressure<0.05MPa, with a linear speed of ≤ 15m/s.
Spring free BV
Single lip internal skeleton rubber oil seal without spring.
Generally suitable for low-speed working conditions, the sealing medium is lubricating ester. Linear speed ≤ 6m/s.
Outer skeleton single lip W
Single lip exposed skeleton rubber oil seal with spring, slim waist, good tracking performance, and good rigidity.
Ordinary oil seals are used in environments with less dust and impurities, and are resistant to medium pressure<0.05MPa. When the rotational axis speed is ≤ 15m/s.
