JWB Ball Screw Jack – Load Capacity Range & Selection Guide
JWB Ball Screw Jack – Load Capacity Range & Selection Guide
The JWB series ball screw jack is a high-efficiency linear actuator designed for high-speed, high-frequency
industrial applications. Unlike trapezoidal screw jacks, JWB uses rolling friction through precision ball
screws, delivering higher efficiency, faster operation, and longer service life.
Load Capacity Range
JWB series covers a standard load range from 0.5 tons to 100 tons
| Model | Max Load (kN) | Max Load (tons) |
|---|---|---|
| JWB005 | 4.90 | 0.5 |
| JWB010 | 9.80 | 1 |
| JWB025 | 24.5 | 2.5 |
| JWB050 | 49.0 | 5 |
| JWB100 | 98.0 | 10 |
| JWB150 | 147 | 15 |
| JWB200 | 196 | 20 |
| JWB300 | 294 | 30 |
| JWB500 | 490 | 50 |
| JWB750 | 735 | 75 |
| JWB1000 | 980 | 100 |
Critical Selection Note
JWB ball screw jacks DO NOT have self-locking capability. Unlike trapezoidal screw jacks, they cannot hold a load when power is off. An external brake is always required for load retention.
Key Advantages
High efficiency – rolling friction requires minimal drive power
High speed – significantly faster than trapezoidal screw jacks
Long service life – quality ball screws extend working life
Ideal for – automation, high-frequency cycles, precision positioning
