JB Series standard screw jacks (ball screw)
A high performance ball screw has been adopted that offers high-efficiency, low noise operation.

Features
This series uses a high-performance ball screw.
The nut and worm wheel have been integrated for a more compact design.
The Worm Speed Reducer is lubricated with an oil bath. This gives it ample durability even during high-speed operation.
An ideal bearing structure offers high performance.
A wide variety of standard jacks is available from 5 kN to 1250 kN.
Structure
[JB005 & JB010]

●Screw shaft end
Select from a rich variety of fitting configurations.

●High precision, large screw shaft
This series uses a ball screw.

●Ideal bearing structure
This series uses a tapered roller bearing that is durable against both thrust and radial loads.

●Integrated ball nut and worm wheel
Because the structure allows for the load to be stably and uniformly distributed on the ball nut, safety is improved and the product life is extended.

●High precision worm wheel
This series uses a special aluminum bronze material which has been machined with high precision and offers ample strength.

●Screw shaft guide
A screw guide is provided on the ball nut to minimize drift of the screw.

●High efficiency reduction
This design offers the benefits of many years of experience with Worm Speed Reducer.

●Grease lubrication
Grease lubrication offers easy maintenance.

●Light weight housing
The housing is manufactured from diecast aluminum and is both lightweight and compact.

●Large input shaft
This series offers ample strength for the use of multiple connected jacks.
