Main characteristics of FTM keyway bearing rings:
The keyway bearing ring is usually round, with the keyway cut into its circumference.
The keyway can accommodate keys that fit into the appropriate slot on the shaft or housing, ensuring a safe fit.
Type of keyway bearing rings:
Plain keyway bearing rings: Standard design, single keyway, suitable for most applications.
Multi-keyway design: Some rings may have multiple keyways to increase versatility and enhance torque transmission.
Function of keyway bearing ring:
Its main function is to lock the bearing on the shaft or other rotating parts to prevent axial movement.
They help to transfer torque from the shaft to bearings or other additional parts, providing stability to the mechanical system.
Application program:
Machinery: Used in various machinery, bearings are installed on the shaft and need to be fixed.
Automotive: Commonly used in automotive applications, such as drive shafts, where safe connections are critical to performance.
Industrial equipment: for conveyors, rollers and other equipment that requires precise alignment and positioning.
Installation:
Keyway bearing rings are installed by sliding them onto the shaft so that the keyway is aligned with the key and then fixed for assembly.
Proper alignment is the key to ensure smooth bearing operation and avoid excessive wear.
Advantages:
Safe fit: Keyway design ensures safe connection and prevents slippage or misalignment during operation.
Easy assembly: Simplify the assembly and disassembly process, making maintenance and repair more straightforward.
High torque transmission: Efficient torque transmission is achieved, making it suitable for applications that require a large amount of power transmission.
