Tata GBS 75 Fix Ring Steel Synchronizer Rings are coordinating component speeds and inhibiting gear engagement until synchronisation is accomplished. These rings are mechanical components that equalise the gear rotation so that the sliding sleeve can interact with it. The synchronizer ring material's friction characteristic is responsible for this. Tata GBS 75 Fix Ring Steel Synchronizer Rings are tested under various parameters to ensure their high quality and effectiveness. These rings are made from a variety of materials, depending on the use.
