Description
The Rotary FlexiSeal® should be used when speeds are
relatively low (<1000 sfpm) and pressures are high (up to
10,000 psi). FlexiLip™ and FlexiCase™ profiles should be
used when pressures are low and speeds high. Rotary
FlexiSeals feature either a flanged design or an O-ring on the
OD to keep the seal fixed in the bore as the shaft rotates. The
O-ring can either be centered along the OD or be located in
the heel of the seal. Virtually any O-ring material can be
supplied with a custom rotary FlexiSeal®, but a fluorocarbon
material is standard.
Choosing the Right Design
While choosing the right rotary FlexiSeal® for your application, you need to consider:
- Pressure
- Shaft Velocity
- Lubrication
- Shaft Misalignment
- Shaft Runout
- Shaft Hardness
- Shaft Surface Finish
- Different Spring Choices
- Lip Shapes
- Shaft Lead
