High-Performance Hydraulic Filter Replacements for Rexroth Series

Product Overview:

This filter element series is engineered as a premium replacement for Bosch Rexroth original parts, covering essential part numbers such as R928049576 and R928049185. Serving as the “protective shield” of precision hydraulic systems, they play a vital role in 2026 across high-efficiency power units, plastic processing machinery, and automated production lines. Utilizing advanced microglass media, they ensure fluid integrity remains within ISO 4406 standards, safeguarding expensive pumps and servo valves.

Core Part Numbers Covered:

• R928049576

• R928049185

• R928018887

• R928054757

Key Technical Advantages:

• High-Efficiency Media (Betamicron Technology): Features multi-layer gradient-structured inorganic glass fiber providing absolute micron-level filtration. A beta ratio of $\beta_x(c) \ge 1000$ ensures extreme retention of even the smallest suspended particles.

• Superior Collapse Stability: Optimized for high-pressure conditions with reinforced galvanized inner cores. The structural integrity remains secure during cold starts, high-viscosity fluid cycles, or instantaneous pressure pulses, eliminating the risk of element collapse.

• Low Pressure Drop & Massive Dirt Holding: Scientifically optimized pleat geometry maximizes the effective filtration area. This reduces the initial operating differential pressure and provides superior Dirt Holding Capacity (DHC), significantly extending service intervals.

• $100\%$ Physical Interchangeability: Manufactured to strict industrial dimensional tolerances, guaranteeing a perfect fit with original Rexroth housings. Equipped with high-grade NBR seals for a zero-leakage connection.

• Thermal & Medium Compatibility: Compatible with anti-wear hydraulic oils, synthetic lubricants, and mineral oils. Maintains peak performance across a temperature range of $-30^\circ\text{C}$ to $+110^\circ\text{C}$.

Detailed Specifications:

• Filtration Rating: $3\mu\text{m}, 6\mu\text{m}, 10\mu\text{m}$ (depending on part number configuration).

• Filter Media: High-performance composite Microglass.

• Support Structure: High-strength galvanized or stainless steel perforated cores.

• Seal Material: Nitrile (NBR) [Viton/FKM optional].

• Pressure Rating: Compatible with Rexroth standard high and medium pressure series.
