U Series Power Cylinder

Introducing the new smaller, lighter U Series Power Cylinder with more than 6 tons rated thrust

Launched June 1, 2017

A new power cylinder that succeeds in providing a smaller, lighter unit with better cost performance while maintaining the same performance of the previous model (T series).

1. Features of U Series Power Cylinders

Lightweight and compact

Thanks to newly developed special ball screws and bearings, we succeeded in reducing the total length by a max. of 11% and the mass 40% compared with the previous model (T series). The smaller size and lighter weight makes it easy to replace hydraulic cylinders.

Complete line-up available

We added a model with a 22 ton rated thrust that we did not have previously. In addition, we will release 32 ton and 50 ton models in 2018. We can now replace hydraulic cylinders in the large thrust range.

Better cost performance
In addition to achieving cost reductions compared to previous models thanks to smaller and lighter parts, the power cylinder is electrical so it has much better power savings than hydraulic types, greatly reducing power consumption.

2. 2. Two types of safety mechanisms for U Series Power Cylinders

Two types are available, depending on the safety mechanism

B type (with wet slip clutch)

A wet slip clutch is built in at the end of the reducer screw shaft. The use of a special lining provides protection during overloads.

C type (with thrust detection unit )

A thrust detection spring unit is built in to the bracket. It is effective during push/pull stopping or when electrical signals are required during overloads.

When replacing the T series

U Series N type models compatible with the T Series mounting dimensions are available. Since the N type more than triples the expected travel distance of the ball screw over previous models, it contributes to reduced cylinder replacement frequency.

Reference Number System: LPUB6000LN5VT1LPCUJF-TK

■ N: N type (For replacement of the T series) ■ Please add "TK" to the end of the model number.
