Product description

 Oil seals - often called grease, fluid or dirt seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. They also stop harmful contaminants from entering machinery, particularly in severe environments. Vital components of practically every type of machine and vehicle in operation, oil seals protect all types of precision-constructed, close-fitting ball, sleeve and roller bearings.

 In precision bearings, oil seals help prevent lubricants from escaping the bearings or a specific area. In machine components, oil seals help prevent abrasives, corrosive moisture and other harmful contaminants from entering machinery. They also help stop intermixture of two different mediums, such as lubricating oil and water.

 To ensure optimal performance, it is necessary to select the appropriate oil seal type and material  for the actual operating conditions. If the fkm oil seal you need (type, material, or dimensions) is not  listed, please contact us regarding customized products

      

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
