Product type
Torque converters are fluid coupling devices used in automatic transmissions to transfer power from the engine to the transmission. They consist of three main components: the impeller, turbine, and stator, which work together to convert engine torque into usable power for the vehicle's drivetrain. Typically made from durable metals and engineered plastics, torque converters allow for smooth acceleration and deceleration by adjusting the amount of torque transmitted based on engine speed and load conditions.
| Material | Aluminum or steel housing with internal components made of various alloys |
| Torque capacity | Typically ranges from 100 to 500 lb-ft |
| Diameter | Common sizes range from 9.5 to 12 inches |
| Transmission compatibility | Designed for specific automatic transmission models |
| Stall speed | Varies from 1,500 to 3,000 RPM depending on application |
When selecting a torque converter, buyers should consider the specific application and vehicle type to ensure compatibility with the transmission system. Key specifications to specify include torque capacity, stall speed, and any necessary certifications for performance standards. Additionally, buyers should determine the required quantity and whether any custom modifications are needed for their specific setup.
