Type and use of oil seals
- Jul 18, 2018 -

Ordinary single lip type B (SC)

Generally used for high, low-speed rotary shaft and reciprocating movement sealing mineral oil and water and other media.

Ordinary oil seals, in the case of dust and impurities less than the situation, resistance to medium pressure <0.05mpa occasions, the highest line speed 15m/s, reciprocating motion speed <0.1m/s .

Common lip-shaped fb (TC)

In addition to the use of the S-type oil seal, but also dust-proof.

General oil seals, with dust-proof lip can be dust-resistant, medium pressure <0.05mpa occasions, line speed ≤15m/s.

Non-Spring BV

Single-lip-type inner-shell rubber oil seal without spring. Generally applicable to low speed operating conditions, sealing medium for lubricating ester.

Line Speed ≤6m/s.

Outer skeleton single Lip shape w

With spring of the single lip exposed skeleton rubber oil seal, waist fine, follow the good, rigid good. Ordinary oil seals, in the dust and impurities in the case of less use, resistance to medium pressure <0.05mpa occasions.

The ≤15m/s of the rotational axis velocity.

External Skeleton Double Lip type FW

With the lip of the two lips exposed skeleton rubber oil seal, waist fine, follow the good, high stiffness, coaxial degree is good. General oil seals, with dust-proof lip can be dust-resistant, medium pressure <0.05mpa occasions.

Speed ≤15m/s.

Assembled single lip-shaped FZ

The outer skeleton oil seal, which is assembled by the internal and external skeleton, has the characteristics of high installation precision, fast heat dissipation and heavy load.

It is suitable for heavy load under high temperature and high speed condition, medium pressure ≤0.05mpa, top line Speed ≤15m/s.

Unidirectional reflux Sr, L-DL

In the lip of the air measurement with angled ribs, using the principle of fluid mechanics, a one-way pump suction effect, with reflux effect.

With the rotation direction of the shaft, due to the backflow effect, radial force than ordinary oil seal small, reduce wear and heat, improve service life, suitable for medium pressure <0.05mpa occasions, speed ≤20m/s.

Pressure-resistant NY

Lip short, waist stubby, has the pressure-resisting function, the work pressure ≤3mpa. Suitable for media pressure ≤3mpa occasions, suitable for high-pressure pump shaft end oil seal, under normal circumstances PV value ≤8.

Rotational axis speed ≤15m/s.
