Concentric Slave Cylinder vs Release Bearing

Orient is your trust hydraulic throwout bearing supplier in China which has made two efforts to ensure strict quality control. A complete dynamic recording mechanism for supplier quality has been established based on raw material evaluation. After confirming that the quality of raw materials provided by suppliers meets the requirements, raw materials can be accepted for storage, ensuring product quality stability from the source. Simultaneously, all produced bearings are subjected to a 100 percent comprehensive inspection before shipment, and only the inspection data can be sent to customers if they meet the requirements of the drawings. As a result, quality will not be an issue for you from the moment you call Orient with your order.

Concentric Slave Cylinder vs Release Bearing

There are a variety of concentric slave cylinder models. Some contain a spring that returns the cylinder to the transmission’s front plate, but others do not. In any instance, the dimensional distances between the cylinder and the clutch finger must be maintained for clutch finger travel to function properly.

A concentric slave cylinder is one of the most prevalent types of cylinders utilized in gearboxes. It consists of a stepped bore and a piston with two portions, the first of which is sized for contact with the first segment of the bore and the second of which has an outside profile that corresponds to the first. Bore and piston define a hydraulic chamber into which a release bearing is fitted to permit rotation of the slave cylinder.

The two basic components of a vehicle’s clutch system are the release bearing and concentric slave cylinder. The release bearing can typically be repaired, but the concentric slave cylinder cannot. Therefore, when it is time to repair the clutch, both components must be replaced. Replacing one without the other could result in costly repairs.

The release bearing and the concentric slave cylinder restrict the piston from revolving in the release bearing in different ways.

The release bearing is also intended to reduce wear on the guide and seals of the slave cylinder. Because the slave cylinder is in constant contact with the outer ring, the axial run-out of the diaphragm spring causes the release bearing to oscillate, resulting in increased wear at the contact points between the release bearing and slave cylinder. This swaying motion is conveyed to the slave cylinder during clutch engagement and disengagement.

Compared to the release bearing, the concentric slave cylinder is more straightforward and resilient. A replaceable angular contact release bearing maintains contact with the diaphragm spring. Easy to diagnose and service, the concentric slave cylinder has fewer moving components than the release bearing.

Clutch release bearings have established a name within the automobile sector. Today, practically every vehicle on the road use this technology. It has a variety of uses, including off-road and all-weather.

The concentric slave cylinder was introduced for use on light trucks as a clutch release device. This system is distinguished by its simplicity, dependability, and maintenance friendliness. It is very simple to troubleshoot and requires no additional components. A angular contact release bearing maintains contact between the pressure plate diaphragm spring and the concentric slave cylinder. A bearing failure could lead to the failure of the remainder of the CSC.

External slave cylinders are mounted externally to the transmission bell housing. They are equipped with a piston, an internal spring, and a pushrod. A mushroom-shaped bushing is located at the end of the pushrod to prevent excessive surface wear. A plastic bushing determines the length of the pushrod overall. The length of the pushrod is crucial to the performance of the hydraulic system.

A concentric slave cylinder consists of a housing with a bore and an annular piston movably positioned within the bore. The piston of the slave cylinder also has a releasing bearing. The release bearing prevents the piston from spinning within the bore, whereas the concentric cylinder permits axial piston movement.

An external slave cylinder, on the other hand, is located outside the transmission bell housing and consists of a piston, an internal spring, and a pushrod. Additionally, the slave cylinder has a rubber boot to seal the moving parts. The release bearing maintains contact with the preloaded diaphragm spring, while the pushrod’s mushroom-shaped bushing reduces surface wear. In addition, the length of the pushrod is essential to its successful operation.

A slave cylinder that is concentric can be employed with either push or pull clutches. These slave cylinders are compatible with any actuation mechanism. In contrast, push type clutches utilize release bearings positioned on a piston. When the slave cylinder comes into contact with the release lever, release bearings are designed to activate or disengage a related clutch.

A slave cylinder that is concentric permits a more precise and convenient clutch release. It eliminates the requirement for a clutch fork and reduces clutch pedal pressure. Additionally, it is self-adjusting and can assist prolong the clutch’s life. Additionally, it eliminates excessive bearing travel, extending its lifespan.
