Product features details
Features of endless products (for rotary motion)
- It can be used for long spans and has a large degree of freedom in design. Since the belt length can be set freely within the range shown in the above table, it is possible to rotate the belt over a long span.
- Can be used for long-span light transmission (synchronous transmission). Even if the distance between the motor and the driven motor is large, synchronous transmission is possible as long as it is within the belt length range in the above table.
- Synchronous transport without slip is possible. Synchronous transport is possible due to the accurate engagement of the belt and pulley.
