SACHS RCS 140 S5.2 Racing Clutch Disc 881864002303
Sinter pad clutch disc with 5.2 mm lining thickness for SACHS RCS 140 racing clutches
The SACHS RCS 140 S5.2 sinter pad clutch disc 881864002303 is a high-quality driven plate for modular SACHS RCS 140 multi-plate racing clutches. It combines the very compact 140 mm diameter with 5.2 mm lining thickness and is designed for direct power transmission, fast response and demanding motorsport conditions.
This version is suitable for applications where the low rotating mass of the RCS 140 system must be retained while more material reserve than thinner sintered versions is required. The S5.2 variant provides a balanced setup between agility, thermal reserve and durable service life.
Compared with the 7.8 mm version, this clutch disc remains more responsive and supports rapid engine speed build-up. Compared with very thin discs, it offers more friction material volume for repeated starts, dynamic load changes and intensive operating profiles.
The part number 881864002303 identifies the specifically selected version with the correct hub profile for the respective gearbox input shaft. This clutch disc is intended for use within approved SACHS RCS 140 clutch configurations.

Technology
Sintered metal friction pads 5.2 mm
The SACHS RCS 140 S5.2 sinter pad clutch disc 881864002303 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 provide a durable friction pairing with direct engagement behaviour.
The 5.2 mm lining thickness offers a practical balance within the compact RCS 140 system: more material reserve than thinner sintered versions, but lower rotating mass than a 7.8 mm clutch disc. This keeps the clutch system highly responsive while remaining durable for intensive operating profiles.
Sinter pad clutch discs respond more directly than organic clutch discs and are designed for typical motorsport operating conditions with high engine speeds, high torque and dynamic load changes.
Hub profile
The hub profile of the SACHS RCS 140 S5.2 clutch disc 881864002303 is matched to the respective gearbox input shaft. This creates a precise-fit connection between clutch disc and gearbox, which is essential for clean power transmission and high operational reliability in motorsport.
When replacing a worn clutch disc, the existing hub length version of the SACHS RCS 140 clutch must be retained exactly. For new builds, conversions or individual assembly of an RCS 140 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 clutch configuration.
SACHS RCS 140 system
As part of the modular SACHS RCS 140 clutch system, the clutch disc is combined with approved pressure plates, intermediate plates and clutch covers. The number of discs, lining thickness, installation height and correct matching of the complete clutch pack are decisive.
The part number 881864002303 identifies the specific version of this SACHS RCS 140 S5.2 sinter pad clutch disc. For safe function, the clutch disc, friction partners, clutch cover, pressure plate, intermediate plates and installation space must be considered as a complete system.
