SME-L Linear Bearing Pillow Block Features
The SME-L long open linear bearing housing is an open, double-Asian metric version. Two LM-OP open linear bearings are mounted in the housing and arranged in a straight line. The advantages of linear bushings include less tilt or friction, which results in less wear and better machining results over time.
If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect solution to install this aluminum bearing housing with LM-OP open linear bearings. Aluminum housing size range: length (L) ranges 75-175mm; width (W) ranges 40-90mm; height (F) ranges 27.6-72mm; minimum item SME12L (linear bearing inner diameter 12mm) combination size is 75*40* 27.6mm, the maximum item SME40L combination size is 72*90*72mm, and the product size error is between±0.02mm. The aluminum housing has four CNC drilled holes, threaded holes and countersunk holes of the same specification from M5 to M10, which can be easily and safely mounted to almost anything.
The typical CNC system includes the matching SBR shaft support rails
. The linear bearing opening angle (θ) ranges from 50° to 80°, and the diameter ranges from 12 to 40 mm. The open bearing housing opening is oriented toward the shaft support rail base. Each end fits in, and the bearing housing with linear bearing runs along the shaft. Most CNC machines have two such components mounted side-by-side, using a housing as a stand to support the mobile platform. Positioning and accuracy enhancement is facilitated by being used as a side aspect of the datum. The extruded aluminum housing is subjected to sufficient extrusion and heat treatment to create a compact, lightweight and precision product.
