Compact Carriage

June 3, 2004
The BMK Ball Monorail Carriage features reduced height, length, and width that allows for a low-profile stage with less mass.


There are two sizes-BMK 15 and BMK 20. Dimensions range from 24 to 28 mm in height, 34 to 44 mm in width, and 37 to 47.7-mm long. Static loading capacities range from 8,500 N for size BMK 15 and 13,100 N for BMK 20. Dynamic loading capacities range from 5,200 N for BMK 15 and 8,400 N for BMK 20. Running characteristics include: low pulsation, low friction and high speeds. Rigidity comes from use of a trapezoid-shaped rail cross section which also stands up well to moment loads. Selected ball arrangement gives the guideway high load bearing capacity equal in any direction. Balls are securely held in the tracks of the carriage at all times so there is no need for an assembly rail during carriage installation or removal. 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 carriage comes in three preload categories, four accuracy grades, and has single rail lengths of up to 6,000 mm. Maximum speeds can hit 5 m/sec and accelerations 100 m/sec2.
