V-ring Seals and Deflectors

The bodyguards of sealing technology

V-Ring Seals and Deflectors from Freudenberg Sealing Technologies

V-Ring Seals and Deflectors must withstand a great deal. Even during installation, they are stretched over the shaft and pushed against their subsequent seat. Their counter faces are often badly processed. Shaft misalignment is yet another concern. Nonetheless, they do something amazing during their operation. They brace themselves against external influences, protecting the actual seal elements of the sealing system – along with the bearings lying behind them.The V-Ring Seals and Deflectors are normally lubricated only during their mounting. That is not a good foundation for a long service life. So Freudenberg Sealing Technologies had to come up with something special to meet heavy industry's often high expectations in this area.

Constant line contact of the sealing even in the case of significant shaft misalignment

FST Enviromatic

The design of the seal lip is crucial for the high functionality of a V-Ring Seal or Deflector. While the very flexible seal lip of a standard V-Ring Seal lies flat against the counter face – which is generally sufficient for secondary applications – the FEM-optimized seal lip of the Merkel Enviromatic exhibits a completely new behavior. With a defined force, it retains its line contact even in the case of major deflections of the counter face. In this way, the tribological properties in the seal gap continue to be controllable. The result is superior sealing effectiveness.

But that is only half the story. To achieve a long service life as well, this new Freudenberg Sealing Technologies development is rounded out with a special material mixture and reservoirs for lubricant intake.

High-performance Enviromatic deflectors are available in A and AX versions and can be used in the installation space available for standard V-Ring Seals.
