Radial shaft seals with one or more sealing
lip(s) of PTFE are designed to withstand e.g.
aggressive environments, high temperatures,
high pressures and non-lubricated services
that traditional radial seals do not withstand.
Radial shaft seals series RD are designed
with a PTFE lip fastened in a metal case.
Housing dimensions according to DIN 3760 or
special designs.
Radial shaft seals series RD can be
assembled in existing housing grooves where
traditional radial seals are used, provided that
they are produced in accordance with DIN
3760.
Series RD can be delivered with a metal
case of steel, aluminium and the stainless steel
materials M1 SS 304, SS 316 and SS 316 TI.
The PTFE material is to be chosen among
several materials in order to adjust to each
application’s specific demands.
Radial shaft seals can also be produced purely
of PTFE without a metal case. These are used
e.g. in the food industry to enable dismounting
of the equipment for cleaning. Radial lip seals
of PTFE are also suitable for applications in
aggressive environments or with temperatures
below –20°C.
Type RDD without metal case has the same
housing dimensions and the same technical
specifications as type RD with a metal case.
