Specifications / Overview

Waste discharge feature lets you use it in any orientation, up, down, left or right.

Do you have the following issues?

Issue 1: You want to use ball rollers in various orientations

Issue 2: Rotation is slowed when waste gets inside the ball roller

Try our solutions

Solution 1:: They can be used in any orientation, including face-up or face-down, so you can position it freely.

Solution 2:: The waste discharge feature increases the product's service life and reduces maintenance time compared to conventional products

Waste Discharge Hole Structure

An innovative solution for discharging waste has been achieved

With head dust ejection slit

Ball rollers (milled ball rollers) with waste discharge holes do not bear load on the small ball receiving surface directly below the large ball.
This structure allows for a large number of waste discharge holes at the lowest point of the body or a waste discharge slit at the highest point of the body.
Holes have been machined in the smaller ball contact area—something that was considered difficult with conventional structures—thus allowing debris and water that have gotten inside the structure to be discharged to keep rotation continuing smoothly.
