LPWB Introducing the new the perfect replacement

Tsubaki’s Worm Series features our time-tested high

Comparison between LPWB and our regular Power Cylinder

It’s the ideal replacement

An in-house manufactured high precision worm gear is used in the reducer. The integrated ball screw and gear supporting structure eliminate the need for a bracket and greatly reduces total unit length. Uses clevises on both ends, which is the most widely used hydraulic cylinder mounting method.

Right Angle Worm

The special copper allows the LPWB Series to handle the same heavy loads as jacks. The maximum load capacity is 50 tons in the high thrust zone (with higher loads being considered).

High load capacity

Quiet

The simple structure vastly reduces the number of parts and keeps costs down.

Replacing the helical gear with a worm gear reduces noise.

Low cost

C (clevis fittings) can be combined with Y, K2, K4, P, and R (position detecting units).Wide variety of options

Series Power Cylinder

The brake motor can be accurately controlled with an inverter to allow the speed to be changed as needed. Accurate positioning is also possible because changes in the ambient environment (temperature) or in the oil temperature do not cause mispositioning.

Accurate speed and position control

Ready for operation simply by connecting to a three-phase power supply. No need for large-scale hydraulic piping work or equipment.

Simple installation with no hydraulic piping

Power Cylinders require no hydraulic piping and do not leak oil from the joints. Maintenance is extremely simple, with no need to flush pipes or dispose of waste oil. They are quiet, with no unpleasant oil odors, to help maintain a healthy work environment.

Clean

Power Cylinders are recognized as having low energy costs and for their LCA (Life Cycle Assessment). Their extremely simple system set-up gives them a remarkably high power conversion efficiency.

Low energy costs

Brake motors are used on all Worm Series to allow for reliable load holding at any position, even during a power failure.

Accurate load holding

Life Cycle Assessment is a tool for the systematic evaluation of the environmental aspects of a product or service system through all stages of its life cycle.

Life Cycle AssessmentWhat's LCA?
