HY-PRO HP16RNL525WB hydraulic oil filter element high-pressure precision impact resistant filter element

Analysis of the core advantages of material technology

The HP16RNL525WB filter element features three core performance characteristics: high pressure, precision, and shock resistance, and is suitable for harsh working conditions such as frequent pressure fluctuations and instantaneous high pressure impacts in servo systems. 5 μm high-precision gradient fiberglass filter material, layer by layer interception of fine wear particles and tiny oil sludge impurities, precise control of oil cleanliness, meeting the strict oil standards of high-end servo hydraulic systems, effectively avoiding common faults such as precision valve sticking, action accuracy deviation, and equipment shaking.

Different from ordinary low-pressure filters, this product adopts a thickened double-layer metal support mesh, which greatly improves the overall structural strength and can stably withstand 25MPa rated high pressure and instantaneous pressure impact. The filter layer will not collapse, deform, or puncture. The filter material has undergone dual resin curing treatment, with tightly bonded fibers and strong resistance to oil erosion. There is no fiber shedding throughout the process, preventing secondary pollution of the oil and ensuring the long-term precise operation of the servo system.

WB exclusive wear-resistant and anti-aging sealing configuration, compared with ordinary seals, has stronger fatigue resistance, aging resistance, and repeated compression resistance. It is suitable for high-frequency start stop and frequent pressure changes in servo systems, and is less prone to sealing failure and internal leakage pressure problems during long-term use. The end cap is formed by stamping and welding high-strength carbon steel, with dual reinforcement of bonding and welding. The structure has extremely strong sealing and operates stably without leakage under high pressure conditions. Each finished product undergoes high-voltage withstand voltage testing, integrity bubble testing, and accuracy verification, with strict quality standards compared to imported original products.
