SWA-L Linear Bearing Pillow Block

SWA-L Linear Bearing Pillow Block
ISUTAMI SWA-L long linear bearing pillow block, also known as SWA-L extended linear bearing unit, SWA-L extended linear slide unit or SWA-L extended linear case housing (unit), L is the abbreviation of LONG. It is a product suitable for the British unit market. It consists of a closed aluminum housing with 4 fixing holes and a matching SW standard linear bearing or SSW super linear bearing. The unit has two circlips with a semicircular arch in the middle of the top. There are also two rubber seals (UU) at both ends of the linear bearing to prevent debris or ball bearing contamination. In addition, the aluminum casing is small and light, and has high corrosion resistance.

SWA-L Linear Bearing Pillow Block Features

SWA-L long type linear housing is a closed, double length inch version. It is fitted in the housing with two straight-line SW standard linear bearings or SSW super linear bearings. The closed bearing design of the housing allows for cost reduction by using the end support shaft. The advantage of the linear bushing is not expensive to manufacture and is used in an infinite stroke. When the loading ball contacts the shaft at a certain point, the bearing capacity of the bearing application is very small. High-precision horizontal movement can be obtained by rotating the ball with very little frictional resistance.

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 SW standard linear bearings or SSW super linear bearings. Aluminum housing size range: length (L) ranges 88.9-254mm; width (W) ranges 50.8-152.4mm; height (F) ranges 28.58-92.08mm; minimum item SWA8L combination size is 88.9*50.8*28.58mm, maximum item SWA32L size is 254*152.4*92.08mm, and the length and width are the same as SWB-L long linear bearing pillow block. The aluminum housing has four CNC drilled holes, tapped holes and countersunk holes, with the same size (S) range of 3.94-10.31mm, which can be easily and safely mounted.

A typical CNC system consists of a linear shaft of matching diameter, with a shaft diameter ranging from 12.7 to 50.8 mm, mounted on both ends of the shaft by two end supports, and a linear bearing housing with linear bearings running 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. 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 case has undergone sufficient post-extrusion heat treatment to create a compact, lightweight and precision item.
