THK SSR Series Low Profile Linear Ray and Vehicles

The radal type, assessed in the horizontal guidance arrangements, is the SSR family with a headset ball.

A view of the SSR series

THK SSR series is a coated ball linear guide group used in the assessment of compact horizontal axes with low cut height and radal load order. The body type as much as the nominal size of the car is also determining in the selection. Source catalogue XW gives the short XV and flange XTB groups in separate measure tables. In this first study, the basic model codes written in these tables are preserved. The Y and M signs seen in the old print are listed without removal; the current order comparison is also confirmed in the technical assessment.

The catalogue is: The tables XW/XWM, XV/XVM and XTB in the SSR source catalog are protected exactly the old print codes containing Y. The source documents may contain old printes; the current variation is confirmed prior to order.

When is low assembly height important?

In a mechanism with a limited height for the upper moving table, the total height of the rail and car is an important part of the settlement. But the outer size of the axis is not determined only by the car height. The upper plate, interfaces, connective wire and the lower output of the moving device are also taken into account. Show these measures in the layout to be added to the underlying machine or a narrow storage. A low-profile choice does not eliminate the need to control the load directions and moments.

Difference between XW, XV and XTB

The standard and short body is not enough to compare only over the total length. Connection hole, access to the cave, the settlement on the rail and the source load values are studied together. The need for access from the bottom of the flagship connection layout in the XTB group should also be addressed in the design. The volume that the compression key will enter where the axis is located should be left. Do not expect the same sizes for each body in the list; a combination not in the catalogue has not been produced automatically. Ask for full code information for the required different variants.

Don't describe the direction of the load.

The load in a feed table is often downward, not that other forces will not form during the movement. The swing, the position, the side of the work part and the position outside the axis of the apparatus can produce additional effects. If the vertical lift or reverse assembly is considered, specify this condition in the offer request. Measure the railway distance, the gap between the car centers and the flat distance of the load. Do not mix the radal character of the SSR series with another series that works with the same nominal load order in four directions.

Original technical drawings and measurement tables

Do not check the car and the rail together.

When the car is replaced, damage on the rail installation surface or traces of climbing on the rail should also be investigated. Do not consider the new piece as a solution to all problems of the old system. A axis climbing can also be caused not only by the car's condition, but also by the rail installation surface or rail parallelity. Share the photos of the piece you are looking from the top and side, the distance between the readable code and connection hole. Adding the dimensions of the rail section also helps prevent the wrong selection of a different guide that appears similar.

Source drawings and offer information

In the following technical sections, a page may display the body and connection measures, and the next page may display the other columns of the same table. The drawing link opens these two pages together. Read the measure letters along with the page head; be careful to protect the units and dipnotes. In addition to the model code for the offer, specify the vehicle unit, rail length, working direction and the use environment. The catalogue is a old print and the current production, variants and supply scope for each code in the list is also clarified.

Frequently Asked Questions

Can the SSR model be used on a vertical axis?

Compliance is assessed along with the load directions and moments. specify the vertical application clearly; do not choose only according to the nominal size.

Why is the sign in the codes protected?

Source printing gives these codes in this way. the sign is deleted and the current reward is verified instead of producing a new order code.
