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 Definition

The phrase concentric slave cylinder is used to describe a cylinder with a concentric profile on its input shaft. This sort of cylinder is utilized in motor vehicles for managing friction clutch engagement. It can be made from steel or polymer materials. The following are some common forms of concentric slave cylinders.

Concentric slave cylinder

A concentric slave cylinder is a mechanical device that has a stepped hole and an annular piston movably positioned within it. The piston has a release bearing located on its outer periphery. Because the piston has a suitably formed outer periphery, it is unable to spin within the bore, but is able to slide axially.

A concentric slave cylinder is positioned on a quill tube inside the bell housing and is able to eliminate the clutch fork and linkage that require pedal effort to operate. This style of architecture also protects the clutch components from road debris and weather conditions. It is also used to replace a clutch fork, which demands pedal exertion when the vehicle is stationary.

The master cylinder converts non-hydraulic pressure into hydraulic pressure and is responsible for managing the slave cylinders. The master cylinder actuates the slave cylinders by moving a piston. The piston then passes through hydraulic fluid to the slave cylinder. The fluid inside the slave cylinder is compressed by the hydraulic pressure provided by the moving piston. A master cylinder is generally positioned at one end of the transmission shaft while the slave cylinder is mounted at the other.

The concentric slave cylinder is a type of hydraulic cylinder .

A concentric slave cylinder is frequently utilized in hydraulic clutch systems. Using a circular slave cylinder for clutch systems might be a challenge, as it is more difficult to prime. Therefore, it is recommended to prime the slave cylinder with fluid before installation. Alternatively, a concentric cylinder can be employed without a clutch.

A typical concentric slave cylinder contains a casing that surrounds the gearbox input shaft and mounts to a vehicle. The piston carries a clutch release bearing and is axially movable. The piston and housing define a hydraulic chamber, which is filled with hydraulic fluid. The hydraulic seals prevent the hydraulic fluid from leaking.

The non-circular profile of a concentric slave cylinder is meant to prevent the piston from turning. This is done by using complimentary non-circular shapes on the slave cylinder. The housing and piston have a high seal fill ratio. This guarantees that the piston and slave cylinder remain in their desired locations.

Another feature of the concentric slave cylinder is its two-piece design.

The concentric slave cylinder contains a stamped steel inner cylindrical member and an injection-molded polymer outer cylindrical member that are linked by overlapping base flanges. The slave cylinder is also referred to as a hydraulic slave cylinder, and the master cylinder regulates the function. Concentric slave cylinders are utilized in auto gearboxes and are positioned inside the bell housing. They have various advantages, including precision release bearing travel, superior alignment geometry, and a closer fit to the transmission. Moreover, the huge coil spring within the slave cylinder maintains consistent contact between the bearing face and diaphragm spring fingers.

Advantages

The concentric slave cylinder has several advantages over a traditional cylindrical cylinder. For example, the conical form of the main section compensates for the non-circularity of the cylinder housing. The concentric shape can also be used for clutches. It is also easier to maintain and service compared to conventional cylinders.

Another advantage of a concentric slave cylinder is that it is more efficient. It can be used to control multiple cylinders simultaneously and can be applied to multiple locations. This allows the driver to monitor cylinder performance and adjust the slave to a precise set point. In addition, it can also be operated manually.

Another advantage of a concentric slave cylinder is that it eliminates clutch forks and linkage. It also reduces pedal effort. Additionally, a concentric slave cylinder can eliminate the need for shims. It also reduces the possibility of a leak if the pressure chamber is loaded.

Concentric slave cylinders are easy to troubleshoot. This means fewer other parts and a longer life for your clutch. It also features a replaceable angular contact release bearing that ensures constant contact between the bearing face and pressure plate diaphragm spring fingers.
