2600R & R928 Series High-Performance Hydraulic Oil Filter Elements

Product Overview:

This range of filter elements spans internationally recognized Hydac styles, Rexroth part numbers, and Leemin standards, providing premier particle control for large-scale hydraulic systems. Essential in 2026 for heavy engineering machinery, power plant lubrication, and steel rolling mills, these elements utilize Betamicron (inorganic glass fiber) and premium mesh technologies to maintain extreme fluid cleanliness under high differential pressure and flow surges.

Featured models: 2600R005BN4HC, R928041208, R928041203, WU-100x100F-J, and RFA-250x20L-Y.

Key Technical Advantages:

• Superior Dirt-Holding Capacity (BN4HC): Utilizing multi-layer gradient glass fiber media. The 2600R size is specifically engineered for high-volume return lines, intercepting $5\mu\text{m}$ wear particles while maintaining a minimal pressure drop.

• Rexroth OEM Standardization: R928041208 and R928041203 are manufactured to the 2026 Rexroth production standards, ensuring $100\%$ physical interchangeability and matching $\beta$-ratings.

• Full Application Coverage:

  • WU-100x100F-J (Suction Type): Protects pumps from coarse contaminants; features a self-sealing valve for maintenance without draining the tank.

  • RFA-250x20L-Y (Return Type): Specifically for return lines, equipped with a bypass valve and clogging indicator ports for system safety.

• High-Collapse Strength: Features reinforced galvanized steel cores and precision pleating to prevent media collapse or rupture during cold starts with high-viscosity oil.

• Reliable Sealing: Standard high-grade NBR seals, with Viton (FKM) options available for high-temperature or specialized synthetic fluids.
