surface finish
- May 20, 2021
The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.
Whether you're working with o-rings, gaskets, or oil seals, each has a unique surface finish recommendation. Optimizing and staying within the recommended limits will help your equipment maintain longer uptime and better sealing performance.
Improving and controlling the ideal surface roughness will usually increase manufacturing costs, which often presents itself as a trade-off between the cost to manufacture the hardware and application performance.
Properly defining, measuring, and controlling surface finish is critical to the functional reliability and service life of a seal.

The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.
In order to control the manufacturing process or predict a component’s behaviour during use, it is necessary to quantify surface characteristics by using surface texture parameters.
Part 5 of our video series on Surface Finish will discuss Amplitude Parameters.
Amplitude Parameters are measures of the vertical characteristics of the surface deviations.
In this section, we will dive into:
- Rp
- Rv
- Rzi
- Rz1max
- Rz
- Rt
- Rq
- Ra
- The advantages and disadvantages of Ra

For nearly every application, the finish on a surface plays a critical role, bringing an enormous impact on performance and longevity.
Each manufacturing process used to acquire a specific surface finish produces a characteristic direction (lay) to the surface which affects wear patterns, performance, and longevity
Gallagher knows it's imperative to bring attention to the importance of surface finish and its relativity to the performance of your seals.
