High-Performance Hydraulic Oil Filter – Models SH65006 & SH56252

Two complementary return-line / low-pressure guards: SH65006 is a large-bore, long-element return filter for high-flow circuits where dirt-holding volume matters more than pressure rating, while SH56252 sits in the mid-flow SH56 family as a versatile return/pressure-guard element for compact to mid-size mobile hydraulics. Both use glass-fiber composite media qualified to ISO 16889 multi-pass, with configurable bypass and seal options.

Key Features

• SH65006: Ø83 mm × 304 mm tall canister, out-in flow, 16 bar collapse — built for tank-mounted return lines

  
  

• SH56252: Compact SH56-series geometry, 21 MPa working option available, suits pump-suction guard or return duty

  
  

• Glass-fiber media, β₁₀ ≥ 200 as standard (β₁₀₀₀ available on request)

  
  

• Bypass valve 2.0 bar (SH65006) / 2.5 bar (SH56252, typical); NBR seals std., FKM/Viton for ester fluids

  
  

Technical Specifications

*SH56252 configurable: 21 MPa for pressure-guard version, 16 MPa for return version.

Application Split

SH65006 – Tank-top or inline return on large agricultural tractors, combine harvesters, sprayers, and stationary power units where return flow peaks are high but line pressure is low. The 304 mm length and 83 mm OD give extended service intervals in dusty environments. Interchanges with common Internormen 01E…VG16SP-type elements (e.g. 300247) and several OEM return cans.

SH56252 – Mid-size loader, telescopic handler, and industrial press return loops; also usable as a suction-guard (100–180 µm version) ahead of the pump if configured accordingly. The SH56 footprint keeps housing size down where bay space is tight.

Installation Notes

• SH65006: Mount vertically tank-top or inline with flow arrow out→in. Confirm housing flange seal condition on each service. Replace when ΔP reaches 2.0–2.5 bar or per小时 log.

  
  

• SH56252: Verify bypass direction and spring setting before install; 2.5 bar std. bypass protects against cold-start starving. For pressure-guard config (21 MPa), torque flange bolts to spec—do not overtighten the smaller end cap.

  
  

Fluid Compatibility

Qualified with mineral oil (ISO HM/HV), HEES/HETG esters (use FKM), and HFC water-glycol. For phosphate ester (HFDR), confirm seal & media compatibility before deployment.

Quality & Testing

• ISO 16889 – multi-pass efficiency & dirt capacity

  
  

• ISO 2941 – collapse/burst

  
  

• ISO 3968 – ΔP vs. flow

  
  

• ISO 2943 – media/fluid compatibility

  
  

• Batch pressure-test before shipment

  
  

Ordering

Quote "SH65006" or "SH56252" with micron rating, seal material (NBR/FKM), and bypass setting if non-standard. Cross-reference to common OEM return elements (Internormen, Deere AH… series, etc.) available on request—provide your machine OEM number for confirmation.

All values nominal; verify against actual system flow peaks, fluid type, and duty cycle before final selection.
