SACHS Motorsport Hydraulic Release Bearing 883182000033
Hydraulic SACHS motorsport release bearing (CSC) for pushed-type racing clutches with 38 mm release diameter.
The SACHS motorsport hydraulic release bearing 883182000033 from ZF Motorsport is a hydraulic concentric slave cylinder (CSC) developed specifically for racing use with SACHS racing clutches using a pushed clutch actuation system. The CSC is positioned concentrically around the transmission input shaft and actuates the clutch directly via the integrated release bearing.
Version 883182000033 combines a 38 mm release diameter with 15 mm travel, defined connection geometry and a one-piece housing. The housing is designed for high strength, sealing reliability and reproducible function under motorsport conditions.
In addition to SACHS RCS racing clutches, this hydraulic release bearing can also be used, subject to suitable technical specification, in racing applications with motorsport clutches from other manufacturers such as Tilton or AP Racing. The release diameter, travel, installation height, mounting pattern, centring and hydraulic actuation system must match the respective clutch and bellhousing.
With its release diameter matched to racing clutches, special surface coating, friction-optimised sealing system and increased hydraulic volume, this motorsport release bearing supports precise clutch actuation, reduced pedal force and a reproducible pedal feel in racing operation.

Technology
CSC 883182000033
Function: The SACHS RCS motorsport release bearing 883182000033 is positioned concentrically around the transmission 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.
Specification: This version features a release diameter of 38 mm and a travel of 15 mm. The axial working positions are defined as X = 46.5 mm in the retracted state and Y = 61.5 mm in the extended state.
Cross-manufacturer use: Its 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 construction supports high strength, sealing reliability and reproducible 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 smooth actuation of the CSC. This improves controllability, pedal feel and repeatability in racing operation.
Hydraulics: Racing clutches generally operate with higher release forces than standard clutches. The SACHS CSC 883182000033 developed for racing has an increased hydraulic volume and a hydraulic cross-sectional area of 820.7 mm² to reduce pedal force for the driver. Nevertheless, master cylinder, pedal travel, hose routing and hydraulic volume must be precisely matched to the vehicle, transmission and clutch.
Geometry & dimensions
Connection geometry 883182000033
The SACHS RCS CSC 883182000033 features a specific connection geometry that clearly defines mounting, centring, release diameter and axial operating 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: 38 mm release diameter
F: 6.6 mm mounting hole diameter
K: 58.99 mm centring diameter
X: 46.5 mm CSC in retracted state
Y: 61.5 mm CSC in extended state
Mounting and centring geometry
Connection geometry: Version 883182000033 uses a mounting pattern with A = 74 mm, B = 33.5°, C = 10°, D = 97°, F = 6.6 mm and K = 58.99 mm. This clearly defines mounting, centring and installation position of the hydraulic release bearing. Release diameter E is 38 mm; the axial working positions are X = 46.5 mm and Y = 61.5 mm.

Installation notes
Installation & specification
Installation height: Before installation, the retracted and extended positions of the CSC must be checked with clutch, flywheel and transmission. For part number 883182000033, the axial reference dimensions are X = 46.5 mm and Y = 61.5 mm.
Release diameter: The 38 mm release diameter must match the respective SACHS RCS racing clutch or a technically suitable motorsport clutch from another manufacturer. Selection must not be based on installation space alone, but must be matched to 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 hose routing must be compared with the bellhousing before installation.
Compatibility check: With Tilton, AP Racing or other motorsport 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 force & master cylinder: The increased hydraulic volume of the CSC can reduce pedal force at high release forces. Actual pedal force depends on master cylinder diameter, pedal ratio, line volume, clutch version and bleeding condition.
Hydraulics: Pedal travel, master cylinder, hose routing and hydraulic volume must be matched to vehicle and clutch. Complete bleeding is essential for consistent function, defined pedal force and reproducible pedal feel.
Service inspection: Bearing, sealing system, connection surfaces and guide must be checked regularly. In the event of leaks, wear, stiff actuation or implausible pedal travel, the motorsport release bearing must be assessed together with the clutch and hydraulic system.
