THK SRS Series Miniature Linear Ray and Car

Compact M and large WM body-covered ball SRS family for small mechanisms.

A view of the SRS series

THK SRS series is a miniature-covered ball product family used to guide linear movement in small settlements. Compact M and wider WM types are displayed in the source catalogue on separate pages. This page covers the basic models of the dimensions of 9, 12, 15, 20 and 25 in the M group; the WM group of 9, 12 and 15. The miniature word does not mean that the application is safe or easy by itself. Connectivity elements, surface preparation and assembly access should also be carefully addressed in this scale.

The catalogue is: The SRS-M and SRS-WM basic models in the source catalog are not included; the SRS-G and other variants not included in the source catalog. The source documents may contain old printes; the current variants are verified prior to order.

Compact M and wide WM body

When choosing between M and WM, the rail width, the vehicle connection layout and the area assigned to the mechanism are studied together. The broad type is not just an extended image of the compact type of the same nominal number. The technical table contains separate body and rail measurements. The side length of the part moving in a single rail layout can be determining; the settlement distance in the two rail design, in contrast, also gains importance. Share the size of the moving plate and the distance of the load to the connection surface to determine which layout is suitable.

Small boxes and connectivity

The position of the end of the wire should be ⁇ checked on a thin plate carrying the miniature car. The wire should not be used that exceed the depths of the hole indicated in the source drawing. Think in the design phase that the upper device should be dissolved to provide access to the distraction process. The connectivity that looks easy from the outside may become difficult in terms of maintenance when a narrow volume enters the machine. The thickness of the plate, the surface to which the head of the wire will sit and the distance to the edge of the piece should be shown in the same installation section.

Installation of small mechanisms

Calculate the total moving mass when designing the measurement order, a small positioning table or a piece feed machine. Just assess the holders, sensors, cables and connector parts connected to it instead of giving the weight of the work piece. The power the cable applies to the axis may not be ignored in a small mechanism. Mark the variable cable swelling and mechanical stops throughout the strok in the drawing. Check also how the clarity between the car centers affects the movement cover when multiple cars are used.

Original technical drawings and measurement tables

When the table is spread to two pages, the drawing link opens both pages together. You can expand by clicking on the image or view the same section in PDF.

Cleaning and access to the oil

The source of pollution on the small rail is not possible to remove from the product name without seeing the working environment. If thin powder, liquid touch or processing is increased, the appropriate protection arrangement should also be considered. Access to the lubrication point should be provided after the mechanism is closed. If it is necessary to remove the entire apparatus for maintenance in a compressed design, it may be useful to re-evaluate the installation. The lubrication arrangement specified by the manufacturer for the relevant type is based on the grass or lubricator must be performed in a different grass or lubricator transition.

Compare the code with the source

SRS9M and SRS9WM are not the same technical line. Keep the M and WM signs while searching for model on the list. Do not confuse close-name families with different structures such as SRS-G with the records of this page. The catalogue here belongs to selected SRS-M and SRS-WM models; it is not claimed to cover all current miniature products. You can examine by extending the source size pages and open the relevant page in PDF. If you have a longer order code in the current section, add the whole and the general appearance of the rail to the offer request.

Frequently Asked Questions

Are SRS9M and SRS9WM in the same range?

The size similarity in the model name is not enough. Compact and wide types should be checked on their own rail cuts and technical drawings.

Are the G-Signs in this list?

The first coverage is the types of SRS-M and SRS-WM coated balls in the source catalogue. Other miniature families are also considered.
