Bosch Rexroth R928006678 Hydraulic Filter Element
Overview
The Bosch Rexroth R928006678 is a hydraulic filter element from the Rexroth Industrial Hydraulics filtration programme, used to trap contamination in hydraulic fluid before it can damage pumps, valves, and cylinders downstream. Rexroth filter elements in this series are built across a range of housing sizes (0040 through 1000) and pressure differential ratings (30 bar, 160 bar, or 330 bar), with filtration ratings starting from 1 µm absolute, allowing a single element family to cover everything from return-line filtration to high-pressure in-line duty depending on the exact order code specified.
Seven Star LLC supplies the Bosch Rexroth R928006678 filter element as a genuine channel to hydraulic equipment operators across Oman and the GCC, supporting industrial plants, marine hydraulics, and mobile equipment fleets that run Rexroth filtration hardware. Because Rexroth filter elements are ordered against a precise housing, micron rating, and differential pressure combination, our engineering team can help cross-reference an existing filter housing’s nameplate or an old element’s part number to confirm the correct R928006678 replacement before ordering.
Measurement and Operating Principle
The R928006678 element works as a depth or surface filtration medium mounted inside a Rexroth filter housing in the hydraulic circuit, most commonly in a return line, pressure line, or off-line filtration loop. As hydraulic fluid passes through the element’s filter media – glass fibre non-woven media, filter paper, wire mesh, or non-woven fabric depending on the specific variant – particulate contamination above the rated micron size is captured within the media structure while clean fluid passes through to the downstream circuit.
Rexroth’s non-woven glass fibre media, the most common construction in this filter element range, provides defined retention capacity in accordance with ISO 16889 multi-pass testing, meaning the element’s contamination removal performance at a given micron rating is independently verified rather than a nominal estimate. This lets hydraulic system designers specify a target fluid cleanliness class (commonly expressed to ISO 4406, such as 18/16/13 or tighter) and select the R928006678 or an equivalent element in the family with confidence that it will deliver that cleanliness level in service.
Engineering Design
Rexroth filter elements in the R928006678 family are constructed with zinc-free components, which prevents the formation of zinc-soap deposits when the hydraulic system uses water-containing fluids or certain synthetic and biodegradable oils – a common requirement on construction and agricultural machinery that specify rapidly biodegradable hydraulic fluids. Zinc-free construction also reduces the risk of premature element blocking and extends practical service life between change-outs compared to elements using zinc-based end-cap bonding.
Depending on the exact configuration, the R928006678 is rated for pressure differential collapse ratings up to 30, 160, or 330 bar, giving it mechanical integrity across return-line, medium-pressure, and high-pressure in-line filtration duty. Multi-layer media construction increases dirt-holding capacity relative to single-layer designs, which extends the interval between element changes and reduces unplanned filter-related downtime on hydraulic power units and mobile machinery alike.

Industrial Applications for the Bosch Rexroth R928006678
The Bosch Rexroth R928006678 filter element is used across mobile hydraulics, industrial hydraulic power units, marine deck machinery, and process plant hydraulic systems wherever Rexroth filter housings are already installed. It is a routine maintenance and overhaul item, replaced on a scheduled basis or whenever a differential pressure indicator signals the element has reached its dirt-holding capacity.
Seven Star LLC, as a trusted supplier of Bosch Rexroth products serving Oman and the wider GCC, supplies genuine R928006678 filter elements to hydraulic maintenance teams in Muscat, Sohar, Duqm, and Salalah supporting refinery hydraulic power units, port cranes, and heavy mobile equipment fleets. Our team can help confirm the correct micron rating and pressure class against your existing housing before shipment to avoid a mismatched replacement.

Why Choose Seven Star LLC for Bosch Rexroth Hydraulic Filter Elements
A hydraulic filter element’s micron rating and material compatibility have to match your system’s actual contamination sensitivity and fluid type, since an under-specified filter lets damaging particulate through to precision hydraulic components while an over-specified one adds unnecessary pressure drop and replacement cost. Seven Star LLC confirms the correct R928006678 filter specification against your hydraulic system requirements before order confirmation, drawing on our regional Bosch Rexroth partnership across Oman and the wider GCC. We also support industrial and mobile hydraulic equipment operators across Muscat, Sohar, and Salalah with planning routine filter replacement schedules and spare stock, keeping hydraulic systems protected without unplanned maintenance interruptions.

Four items are listed. The A10VSO is an axial piston variable displacement pump of swashplate design for open circuits. The DB10G2-5X/50 is a pilot-operated pressure relief valve, and the MHDBD10K2-1X/315V is a direct-operated relief valve in cartridge form. R928006678 is a hydraulic filter element. Older parts may be marked Mannesmann Rexroth; the type codes are read the same way.Ordering Rexroth parts: what we need
The safest reference is the ten-digit material number beginning with R9, printed on the nameplate beside the type code. Send both, with a nameplate photo. For an A10VSO pump, the full code matters: size, controller type, series, direction of rotation, seals, shaft and port plate. For relief valves, give size, pressure stage and seal material. For filter elements, the material number or the complete element code is enough.
