SACHS 883182000035 motorsport hydraulic release bearing
Hydraulic SACHS motorsport release bearing (CSC) for push-type racing clutches with 44 mm release diameter.
The SACHS 883182000035 motorsport hydraulic release bearing from ZF-Motorsport is a hydraulic concentric slave cylinder (CSC) developed specifically for racing, designed for SACHS racing clutches with push-type clutch actuation. The CSC is positioned concentrically around the gearbox input shaft and actuates the clutch directly via the integrated release bearing.
Version 883182000035 combines a 44 mm release diameter with 15 mm travel, defined connection geometry and a one-piece housing. The housing is designed for high strength, sealing integrity and repeatable function under motorsport conditions.
In addition to SACHS RCS racing clutches, this motorsport hydraulic release bearing can also be used in racing applications with racing clutches from other manufacturers such as Tilton or AP Racing, provided the technical setup is suitable. The release diameter, travel, installation height, mounting pattern, centring and hydraulic actuation system must match the respective clutch and bellhousing.
Thanks to the release diameter matched to racing clutches, the special surface coating, the friction-optimised sealing system and the increased hydraulic volume, this motorsport release bearing supports precise clutch actuation, reduced pedal effort and repeatable pedal feel in racing operation.

Technology
CSC 883182000035
Function: The SACHS RCS motorsport release bearing 883182000035 is positioned concentrically around the gearbox input shaft and actuates the clutch directly via the release bearing. This allows release travel, bearing position and actuation force to be precisely matched to the respective racing clutch.
Design: This version has a release diameter of 44 mm and a travel of 15 mm. The axial working positions are defined as X = 46.5 mm in the retracted position and Y = 61.5 mm in the extended position.
Cross-manufacturer application: Use is not limited exclusively to SACHS racing clutches. With racing clutches from Tilton, AP Racing or other manufacturers, compatibility must be checked via release diameter, diaphragm spring contact, required travel, installation height, centring, mounting pattern and hydraulic ratio.
Housing: The housing is designed as a one-piece component. This design supports high strength, sealing integrity and repeatable function under high release forces, vibration and thermal load in motorsport.
Bearing: The release bearing is designed for the high engine speeds of racing engines. It enables stable clutch actuation during rapid load changes, short shift operations and high mechanical loads.
Friction & sealing: A special coating and a friction-optimised sealing system support consistent actuation of the CSC. This improves modulation, pedal feel and repeatability in racing operation.
Hydraulics: Racing clutches generally operate with higher release forces than production clutches. The SACHS CSC 883182000035 developed for racing has an increased hydraulic volume and a hydraulic cross-sectional area of 820.7 mm² to reduce pedal effort for the driver. Master cylinder, pedal travel, line routing and hydraulic volume must nevertheless be precisely matched to the vehicle, gearbox and clutch.

Geometry & dimensions
Connection geometry 883182000035
The SACHS RCS CSC 883182000035 has a specific connection geometry that clearly defines mounting, centring, release diameter and axial working range. Dimensions A, B, C, D, E, F, K, X and Y refer to the SACHS CSC geometry drawing for this version.
A: 74 mm bolt circle for mounting holes
B: 33.5° angular position of mounting holes
C: 10° angular position of mounting holes
D: 97° angular position of mounting holes
E: 44 mm release diameter
F: 6.6 mm mounting hole diameter
K: 58.99 mm centring diameter
X: 46.5 mm CSC in retracted position
Y: 61.5 mm CSC in extended position

Mounting and centring geometry
Connection geometry: Version 883182000035 uses a mounting pattern with A = 74 mm, B = 33.5°, C = 10°, D = 97°, F = 6.6 mm and K = 58.99 mm. Mounting, centring and installation position of the hydraulic release bearing are therefore clearly defined. Release diameter E is 44 mm; the axial working positions are X = 46.5 mm and Y = 61.5 mm.

Installation notes
Installation & setup
Installation height: Before installation, the retracted and extended position of the CSC must be checked with clutch, flywheel and gearbox. For article number 883182000035, the axial reference dimensions are X = 46.5 mm and Y = 61.5 mm.
Release diameter: The 44 mm release diameter must match the respective SACHS RCS racing clutch or a technically suitable racing clutch from another manufacturer. Selection must not be based on installation space alone, but must be matched to the clutch version and release system.
Mounting pattern: This version uses A = 74 mm, F = 6.6 mm and K = 58.99 mm. Mounting holes, centring and line routing must be compared with the bellhousing before installation.
Compatibility check: With Tilton, AP Racing or other racing clutches, release diameter, diaphragm spring contact, required travel, minimum clearance, installation height, stop limitation, hydraulic ratio and return behaviour must be checked before use.
Pedal effort & master cylinder: The increased hydraulic volume of the CSC can reduce pedal effort with high release forces. Actual pedal effort, however, depends on master cylinder diameter, pedal ratio, line volume, clutch version and bleeding condition.
Hydraulics: Pedal travel, master cylinder, line routing and hydraulic volume must be matched to the vehicle and clutch. Complete bleeding is required for consistent function, defined pedal effort and repeatable pedal feel.
Service: Check bearing, sealing system, connection surfaces and guide regularly. In the event of leaks, wear, stiff operation or implausible pedal travel, the motorsport release bearing must be assessed together with the clutch and hydraulic system.
