Product Description
shaft coupling

The plum shaft coupler generally consists of two hub components and an elastic element shaped like a plum blossom. This elastic element can move freely between the hubs, effectively reducing vibrations and impacts.



- The installation of the plum flexible shaft coupling is simple, and it typically doesn’t require moving the connected shafts when replacing the elastomer, making maintenance and replacement easier.
- The Motor coupler can effectively absorb vibrations and shocks, protecting machinery.
- Compensating Misalignment
- Long service life.
- Effective shock resistance
- Motor shaft couplers usually don't require lubrication, are easy to maintain, and can be used in various environments, including high-temperature and humid conditions.
- The elastic material of the shaft coupling can effectively absorb and isolate vibrations, reducing shocks and vibrations in the transmission system.
- Corrosion Resistance
- Easy maintenance
- Vibration absorption and buffering
- Anodized Surface Treatment
Wide Range of Usage
Plum Flexible Shaft Coupler are mainly used for CNC machines,servo motors, spindle, step motor etc.
High precision
The shaft couplings are characterized by high precision and are available in various sizes to meet the diverse needs of our customers.
Strength and Durability
The stepper motor coupler, made from aviation aluminum and treated with anodized surface treatment, is both strong and durable. It can handle heavy-duty applications and is less likely to fail under stress.

- No damage to the shaft
- Reliability Under Stress
- Flexible and convenient elastomeric material.
