Monorail gains linear bearing carriage options

Schneeberger has added three new carriage types to its line of ball monorial precision linear guides.

Schneeberger has added three new carriage types to its line of ball monorial precision linear guides.

The BME, BMF and BMG carriages offer new dimensions and attaching options to complete the full line of Monorail BM carriages.

Carriage BME is available in three sizes - 25, 30 and 35 - with dimensions ranging from 40 to 55mm in height, 57 to 76mm in width, and 90 to 118mm in length.

BME also offers attaching holes located on the side of the carriage.

Carriages BMF and BMG, are available in sizes 15, 25, 30 and 35 and offer more compact dimensions - up to 14% reduced overall height compared with industry standards.

The reduced heights of the carriages allow lower profile stages with less mass.

Both carriages have heights ranging from 24 to 48mm and widths from 34 to 70mm.

BMF offers lengths of 60 to 118mm and BMG is available in 60 to 144mm.

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.

The robust construction of the Monorail BM is evident by the fact that the balls are securely held in the tracks of the carriage at all times.

Therefore an assembly rail for installing or removing the carriage is not required.

Simultaneously, the maintenance effort required is significantly reduced because parts subject to wear can now be replaced without having to dismantle the guideway.

The complete sealing of the carriages guarantees high reliability in conjunction with a long service life.

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 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.
