SACHS RCS 184 S7.8 Racing Clutch Disc 881864002259
Sinter pad clutch disc with 7.8 mm lining thickness for SACHS RCS 184 racing clutches
The SACHS RCS 184 S7.8 sinter pad clutch disc 881864002259 is a high-quality driven plate for modular SACHS RCS 184 multi-plate racing clutches. It combines the 184 mm diameter with 7.8 mm lining thickness and is designed for thermal durability, direct power transmission and reproducible function in motorsport.
The 184 mm format is technically positioned between the very compact RCS 140 and the large-format RCS 200. This gives this clutch disc more friction surface and temperature reserve than smaller 140 mm versions, while remaining more compact and responsive than a 200 mm system.
The S7.8 version focuses on durability and material reserve. It is suitable for vehicles where repeated starts, high clutch temperatures and longer load phases need to be combined with the most compact clutch system possible.
The part number 881864002259 identifies the specifically selected version with the matching hub profile for the respective gearbox input shaft. The clutch disc is intended for use within approved SACHS RCS 184 clutch configurations.

Technology
Sinter pads 7.8 mm
The SACHS RCS 184 S7.8 sinter pad clutch disc 881864002259 is designed for high friction work, high temperatures and repeated load changes in motorsport. The sintered metal friction pads are brazed to the carrier plate and enable a durable friction pairing with direct engagement behaviour.
The 7.8 mm lining thickness provides a large material reserve within the RCS 184 system. This makes this clutch disc especially suitable for applications where service life, temperature stability and reproducible function are more important than the lowest possible rotating weight.
The 184 mm diameter creates a practical middle ground between compact design and thermal capacity. This makes the clutch disc suitable for vehicles where a responsive racing clutch is to be combined with a durable reserve.
Hub profile
The hub profile of the SACHS RCS 184 S7.8 clutch disc 881864002259 is matched to the respective gearbox input shaft. This creates an accurate connection between clutch disc and gearbox, which is essential for clean power transmission and high operating reliability in motorsport.
When replacing a worn clutch disc, the existing hub length version of the SACHS RCS 184 clutch must be retained exactly. For new builds, conversions or individual assembly of an RCS 184 clutch pack, only the factory-approved hub length combinations for the respective clutch configuration may be used.
Before installation, the hub profile should be checked against the existing gearbox input shaft as well as the clutch cover, intermediate plates, pressure plate and approved RCS 184 configuration.
SACHS RCS 184 system
As part of the modular SACHS RCS 184 clutch system, the clutch disc is combined with approved pressure plates, intermediate plates and clutch covers. The decisive factors are the number of discs, lining thickness, installation height and the correct setup of the entire clutch pack.
The part number 881864002259 identifies the specific version of this SACHS RCS 184 S7.8 sinter pad clutch disc. For safe function, clutch disc, friction partners, clutch cover, pressure plate, intermediate plates and installation dimensions must be considered as a complete system.
