SWB-L Linear Bearing Pillow Block

SWB-L Linear Bearing Pillow Block
ISUTAMI SWB-L long linear bearing pillow block, also known as SWB-L extended linear bearing unit, SWB-L extended linear slide unit or SWB-L extended linear case housing (unit), L is the abbreviation of long. It is a product suitable for the imperial unit markets,and it consists of a closed cylindrical aluminum casing with four fixing holes as well as 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 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 the aluminum surface can be oxidized for greater corrosion resistance.

SWB-L Linear Bearing Pillow Block Features

The SWB-L long linear housing is a closed, double length inch version that is fitted in the housing with two linearly aligned 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 a linear bushing is inexpensive to manufacture and used in an infinite stroke. When the loading ball contacts the round 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 88.9-228.6mm; width (W) ranges 50.8-120.65mm; height (F) ranges 31.8-82.56mm; minimum item SWB8L combination size is 88.9*50.8*mm, a maximum item of SWA24L size is 254*152.4*92.08mm, and the length and width are the same as those of SWA-L long linear bearing pillow block. The aluminum housing has four CNC drilled holes, tapped holes and countersunk holes of the same specification with a diameter (S) ranging from 3.94 to 7.16 mm.

A common CNC system consists of a linear shaft with a diameter of 12.7-38.1 mm. Two supports are mounted on both ends of the shaft, and a linear bearing housing with linear bearings 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. 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.
