Schneeberger is announcing the addition of the extremely compact BMK ball monorail carriage to its family of carriages for the BM monorail.

The reduced height, length and width of the carriage offers a space-saving solution that allows for lower profile stages with less mass.

The new BMK carriage is available in two sizes: BMK 15 and BMK 20.

Dimensions range from 24 to 28mm in height, 34 to 44mm in width, and 37 to 47.7mm in length.

Static Loading Capacities range from 8500N for size BMK 15 and 13100N for BMK 20.

Dynamic Loading Capacities range from 5200N for BMK 15 and 8400N for BMK 20.

The BM monorail offers outstanding running characteristics such as: low pulsation, low friction values and high travelling speeds.

Consisting of a few optimally designed components, the BM monorail 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 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 BM monorail comes in three preload categories, four accuracy grades and has single rail lengths of up to 6,000mm.

Maximum speeds of 5m/s and accelerations of 100m/s2 can be achieved.

Typical operating temperatures are -40C to +80C.

Short-term temperatures up to 120C are possible.
