High-Pressure, High Eccentricity Seal Solution Demonstrates 50% Improvement
On pressure and side-load performance of a fluid application
Recently, a customer was having difficulty with a seal failure on a fluid power application. The high-pressure, high-eccentricity seal operates in conditions up to 200,000 pv at 3000 psi and could not exceed maximum shaft deflection of 0.005″.
Unitized seals for input and output pinions in gear boxes, axle wheel ends, and trunnion seals
Vanseal works with these types of seal applications frequently and used a Unitized Seal that uses several components to address each of the various sealing challenges.

High-Deflection Seal Design
The high-deflection seal design solves seal leakage from high shaft-deflection and alignment problems.
Seal leakage arises from many different factors including the misalignment of the shaft to the bore centerline, excessive dynamic runout of the shaft, shaft deflection caused by heavy loads, bearing issues, and improper seal installation. Many OEMs of off-road vehicle equipment, lawn-and-garden equipment, and recreational vehicles struggle with the performance of radial lip seals while under the influence of high lip-deflection from these issues.
Evidence of shaft deflection or misalignment in the sealing system appears as heavy, one-sided wear or as an irregular wear-pattern around the circumference of the seal lip. The wear or offset-loads against the seal lip results in severely reduced seal life, higher torque loads, and excessive heat.
