MONORAIL MR Profiled linear roller guideways

The very precise MONORAIL profiled guide ways are used worldwide in many machine tool applications. A widespread product program is covering the requirements from small manipulators till heavy chipping processes.


MONORAIL MR

High rigidity, great dynamic and static load carrying capacity, outstanding running smoothness and the total enclosure of the carriage are the main features of the MONORAIL guideway. These properties result in higher machining rates while enhancing geometrical accuracy and surface quality of the machined workpieces. Our highly rigid MONORAIL provides improved vibration behavior, smaller vibration amplitudes and thus extends tool life.
SCHNEEBERGER has systematically applied its many years of experience in the design, production and use of roller-type anti-friction guideways in the development of the MONORAIL. Consequently the MONORAIL MR is a cost-effective anti-friction guideway which meets the challenge presented by modern machine design.

MONORAIL BM Profiled linear ball guides

The very precise MONORAIL profiled guide ways are used worldwide in many machine tool applications. A widespread product program is covering the requirements from small manipulators till heavy chipping processes.


MONORAIL BM

SCHNEEBERGER's MONORAIL BM linear ball guides features excellent dynamic properties and many commercial benefits. Designed with a small number of cleverly arranged components, it provides for excellent running properties due to the small number of transitions in the ball tracks, which lead to very quiet running, low pulsation and low friction as well as high travel speeds. The use of a trapezoidal rail section results in an extremely rigid guideway coupled with a substantial reduction in servicing time as additional wipers can be changed without dismantling the carriage. Complete sealing of the carriage guarantees maximum reliability coupled with a long service life.
This robust and economical guideway rounds off SCHNEEBERGER's range of products for industrial applications with high demands on speed, reliability and consistant running properties. Accessories

Stainless steel version

Ball MONORAIL BM WR / BM SR Stainless Steel Version »
Linear ball guides made of stainless steel SCHNEEBERGER MONORAIL BM WR/SR stainless steel guideways are designed for applications where common anticorrosion coatings are not sufficient. This is the case if linear guides are used in an environment conducive to corrosion and in processes which cannot tolerate particle generation from anticorrosion coatings.

Back To Top

MONORAIL BM WR / BM SR

The MONORAIL BM WR/SR systems are linear guides made from corrosion-resistant steel, and are based on the MONORAIL BM ball profiled linear guideway. They were developed specially for specifications which would exceed the requirements of ordinary coatings for linear guideways. This is the case when the performance of the product is impaired by corrosion during processes.
In applications such as machines for foodstuffs, medical technology and cleanrooms, or vacuum applications, MONORAIL BM WR/SR products ensure that the operation of linear axes is clean, accurate, long-term and free of problems.
Furthermore, the MONORAIL WR/SR has the same tried and tested properties of the MONORAIL BM, such as the most effective operating characteristics, high travel speeds and a long operating life.


Advantages

MONORAIL BZ Profiled guideway with integrated racks

The very precise MONORAIL profiled guide ways are used worldwide in many machine tool applications. A widespread product program is covering the requirements from small manipulators till heavy chipping processes.


MONORAIL BZ

SCHNEEBERGER's MONORAIL BZ systems are high-precision linear guide systems with integral rack drive, based on the company's proven MONORAIL BM profile guideways with balls. The benefits resulting from the integration of a profile guideway and an extremely precise rack drive mainly come into their own in the handling and automation industries, in laser and water-jet cutting tools as well as in woodworking machines.
Outlay on the production of machine beds, the installation and alignment of the guideway and gearing are substantially reduced. Single piece rail systems are available up to a length of 6 metres.
The design of the MONORAIL BZ provides for superb operating characteristics, high load-bearing capacity and rigidity together with a long service life thanks to the use of the tried-and-tested MONORAIL BM profile guideway and to the high transmittable forces, smooth running and optimum positioning accuracy offered by ground, hardened and precise helical gearing of superlative quality.


Advantages

- Single-piece system length up to 6000 mm
- Two different sizes BZ 25 and BZ 35
- Toothed rack in a high quality (hardened and ground)
- Cost savings up to 25 % possible through the reduction of expenses on manufacturing and assembly
- Best running characteristics, high load carrying capacity and lifetime based on the MONORAIL BM guideways
- An uncompromising alignment to the customers requirements by means of the utilization of the ball guideway BM and by means of different toothing qualities
