SWB-L-OP Linear Bearing Pillow Block

SWB-L-OP Linear Bearing Pillow Block
ISUTAMI SWB-L-OP long open linear bearing pillow block, also known as SWB-L-OP extended open linear bearing unit, SWB-L-OP extended open linear slide unit or SWB-L-OP extended open linear case housing(unit), OP is an abbreviation for open, and L is an abbreviation for long. This is a product suitable for the imperial unit market. It consists of an open long cylindrical aluminum casing with 4 fixing holes and a matching SW-OP open linear bearing or SSW-OP super open linear bearing, the unit is with two circlips. 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 pillow block surface can be oxidized for greater corrosion resistance.

SWB-L-OP Linear Bearing Pillow Block Features

The SWB-L-OP long open linear bearing housing is a single length inch version. Two SW-OP open linear bearings or two SSW-OP super open linear bearings are installed in the casing. The advantage of a linear bushing is that it is cheaper to manufacture and is used in an infinite linear travel. When the loading ball contacts the shaft at a certain point, the bearing capacity of the bearing application is very small, and the ball is rotated with very small frictional resistance, and high-precision horizontal movement can be obtained.

If you are producing 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-OP open linear bearings or SSW-OP super open linear bearings. Aluminum housing size range: length (L) ranges 88.9-288.6mm; width (W) ranges 53-120.65mm; height (F) ranges 28.7-74.6mm; minimum item SWB8L-OP (supporting SW8OP open linear bearing or SSW8OP super open linear bearing, its combined size is 88.9*53*28.7mm, and the combined size of the largest specification SWB24L-OP (supporting SW24OP open linear bearing or SSW24OP super open linear bearing) is 288.6*120.65*74.6mm. The aluminum housing has four CNC drilled holes, tapped holes and countersunk holes of the same size with a diameter (S) ranging from 3.96 to 7.16 mm.

The typical CNC system includes the matching STBR shaft support rail. The linear bearing opening angle (θ) of the SWB-L-OP extended open type linear bearing housing is constant at 60° and the diameter range is 12.7-50.8mm. In the direction of the base of the shaft support rail, it fits in from one end of the shaft support rail, and the bearing pillow block with the 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.
