Hydraulic Wiper Seals – Protect Your Cylinders from Dirt
Wear rings, or guide rings, stabilize pistons and rods, preventing metal-to-metal contact in cylinders. Made from lubricated nylon or bronze-filled PTFE, they absorb side loads in misaligned oilfield actuators. Linear bearings reduce friction coefficients below 0.1. API 6D valves benefit from these in high-flow scenarios. Proper sizing avoids scoring; tolerances are ±0.05 mm. They enhance seal life by distributing forces evenly. In hydraulic power units for rigs, wear rings cut maintenance costs by minimizing downtime from galling or ovality in bores
