SMA-S Linear Bearing Pillow Block

SMA-S Linear Bearing Pillow Block
ISUTAMI SMA-S short linear bearing pillow block, also known as SMA-S short linear bearing unit, SMA-S short linear slide unit or SMA-S short linear case housing (unit), is suitable for the Asian market. S is an abbreviation for short. This model consists of a short aluminum housing with 2 fixing holes and a matching LM standard linear bearing. Each end of the unit has a circlip. There are also two rubber seals (UU) at both ends of the linear bearing to prevent debris or ball bearing contamination. The casing which is made of aluminum, is small and lightweight, has strong corrosion resistance.

SMA-S Linear Bearing Pillow Block Features

The SMA-S short linear bearing housing is a closed, single-length Asian metric version that is fitted with the LM standard linear bearing. Advantages of the bearing bushing include less tilt or friction, less wear over time, and better machining feature. The SMA-S closed bearing design allows for cost reduction by using end support shafts.

If you are manufacturing CNC milling machines, milling machines or lathes that require precise linear motion, it is a perfect choice to install this short aluminum housing with LM standard linear bearings. Aluminum case size range: length (L) ranges 15.5-69mm (matching LM standard linear bearing length (L) range 17-100mm); width (W) ranges 34-122mm; height (F) ranges 22-102mm. The minimum combined size: item SMA8S is 15.5*34*22mm, and the combined size of the largest item SMA50S is 69*122*102mm. These data are basically the same as those of the KBA-S linear bearing pillow blocks. The aluminum housing has two CNC drilled holes, threaded holes and countersunk holes of the same size with M4-M10, which can be easily and safely mounted to almost any system.

A typical CNC system consists of a linear shaft of matching diameter, with a diameter range of 8-50 mm, mounted on both ends of the shaft by two end shaft supports, and the housing of the short linear bearing runs straight along the shaft. Most CNC machines have two such components mounted side-by-side, using housing as a stand to support the mobile platform. The housing can be mounted from above or below, making it easy to install into the intended system. 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, and create a compact, lightweight and precision product as well.
