Fast-fit cover keeps linear guideways
smooth
Schneeberger has made a significant addition to its line of Monorail BM linear guideway accessories.
Schneeberger has made a significant addition to its line of Monorail BM linear guideway accessories Already available for Monorail MR, the BAC Coverstrip for Ball Monorail is designed as an alternative to the traditional plastic caps that cover the counter-bored mounting holes in a profile rail of a precision linear guideway assembly

Precision linear guides now available from stock
The Schneeberger Minirail series is a family of robust, two-row miniature guideways made from stainless steel, ideal for compact environments.
Slides gain anti-creep roller cages
Type NK and NKL precision linear motion slides are now available with a novel centring mechanism that eliminates cage creep.
BAC Coverstrips give machine designers a virtual one-step alternative to a typically time-consuming, multistep process, and boast a number of advantages.
The cover strip is simply placed on the top of the rail and snapped into a full-length rail groove along where the holes are drilled.
This saves up to 50% of the time normally needed for installing a hole cap in each hole, which can take hours to install on very long rails.

Top quality options for cross-roller bearings
Schneeberger has added two new quality options to its cross-roller precision linear bearings.
Dry linear bearings run on and on
A new line of dry running antifriction precision linear bearings are guaranteed free of organic lubricants, sulphur-containing solid lubricants and are also free of soft metal coating lubricants.
As the width of the cover strip is narrower than the width of the guide rail, an exposed surface on top of the rail that is precision ground can be used as a reference during assembly.
Coolant, dirt and various types of debris will not get inside the bores of the holes.
Wipers are protected during installation because the rough edges of the rail bores are recessed below the groove and do not come in contact with the wipers.
The BAC cover strip is made from stainless steel and offers a rugged cover that will not bend or break from being stepped on or from tools that may be dropped on it during assembly.
In addition, its smooth top surface lengthens the life of the wipers on the ends of the linear carriages that travel along the rail.
The BAC cover strip is 0.5mm thick and thus substantially more robust than competitive designs.
Compared to traditional rail hole caps, the BAC coverstrip reduces installation time, is reusable, and provides increased protection in applications with a high degree of contamination.
Additionally, Schneeberger offers a special tool, the BWC, to facilitate installation of the BAC.
The Monorail BM offers outstanding running characteristics such as: low pulsation, low friction values and high travelling speeds.
Consisting of a few optimally designed components, the Monorail BM achieves high rigidity due to the trapezoid-shaped rail cross section and also has excellent resistance to moment loads.
Due to the selected ball arrangement, this guideway has a high load bearing capacity equal in any direction.
Available in sizes 15, 20, 25, 30, 35 and 45, the Monorail BM comes in three preload categories, four accuracy grades and has single rail lengths of up to 6000mm.
Maximum speeds of 5m/s and accelerations of 100m/s2 can be achieved.
Typical operating temperatures are -40 to +80C.
Short-term temperatures up to 120C are possible.
Customers can now order all sizes and travel lengths from the full line of Monorail BM with second day delivery.
