♠Description-PTFE Lip Seals

Metal cased PTFE Lip Seals are a seal that features a lip on the ID that fastens dynamically on a shaft and metal casing on its OD to press-fit into a bore. Besides, radial shaft seal with one or more PTFE sealing lips. In addition, the material is a resilient sealing lip. Most important, it is designed to withstand the harsh environments that conventional radial shaft seals cannot withstand, high temperatures, high pressures, and dry running.

♣Advantage

● Low friction, long seal life with proper configuration

● Strong chemical resistance

● Surface speeds of up to 10,000 spfm

● Wide temperature range, -65 to 450 degrees F (-53 to 232 degrees C)

● High pressure in excess of 500 psi (35 bar)

● Extended seal life in dry or abrasive media

● Unlimited shelf life

● Large diameter capability

● PTFE seal applications include Motors, Gearboxes, Pumps, and Bearings.

Type	Rotary Condition	Main Performance and Annlication
A	Speed:≤30m/sPressure:≤10bar	Type A is a standard product, adding clockwise thread (type AL)dor anticlockwise thread (type AR) to improve sealing performance.
ARAL	Speed:≤30m/sPressure:≤10bar
C	Speed:≤30m/sPressure:≤10bar	Same as Type A, but has additional lip for dustproof,can beapplied in dust environment.
B	Speed:≤18m/sPressure:≤35bar	Double lips rotary seals, applied in high pressure 35bar,PV:100bar m/s, adding clockwise thread (type BL) or anticlockwise thread (type BR) to improve sealing performance.
BRBL	Speed:≤18m/sPressure:≤35bar
D	Speed:≤18m/sPressure:≤35bar	Same as Type B, but has additional lip for dustproof,can be applied in heavy dust environment
L	Speed:≤30m/sPressure:≤1.5bar	Low friction type,very suitable for application of bearing
LB	Speed:≤30m/sPressure:≤1.5bar	Same as type L,but has additional lip for dustproof,can be applied in heavy dust environment.
LC	Speed:≤8m/sPressure:≤3.5bar	Flexibility reinforced,suitable for poor roundness and largely
LD	Speed:≤8m/s Pressure:≤3.5bar	Same as type LC, but has additional lip for dustproof,can be applied in dust environment.
LA	Speed:≤25m/sPressure:≤1.5bar	With symmetrical sealing lips, which can isolate two different fluids,Such as the application in centrifuge.
