honed cylinder creates a secure seal, smooth operation, and extended seal life for any hydraulic cylinder. The primary objective when refinishing the cylinders is to make the walls as straight as possible, improve bore geometry, and create the right amount of crosshatch surface finish for good oil retention and ring support. In effect hydraulic cylinders are very similar to the engine in your car, however few people consider the bores of hydraulic cylinders with the same level of importance.
Advantages of honing:
- Improved lubrication
- Uniform wear
- Longer seal life
- Correct minor surface irregularities
- Correct geometrical issues
Honing can also be considered an inspection tool due to its ability to highlight surface imperfections after a light hone using a rigid tool. These surface defects may indicate a more severe condition which can be appropriately managed.
