SWD Linear Bearing Pillow Block

ISUTAMI SWD adjustment open linear bearing pillow block, also known as SWD adjustable open linear bearing unit, SWD adjustable open linear slide unit or SWD adjustable open linear case housing (unit), is suitable for imperial system The product of the unit's market. It consists of an open aluminum housing with 4 fixing holes and a matching SW-OP open linear bearing or SSW-OP super open linear bearing. The unit has two circlips at both ends and one side The adjustable gap can be adjusted by elastic screws. There is a piece of iron on each side of the top for fixing the linear bearing. There are usually 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 strong corrosion resistance.

SWD Linear Bearing Pillow Block Features

The SWD adjustable open type housing is an open, single length metric version. The SW-OP open type linear bearing or the SSW-OP super open type linear bearing is mounted in the housing. Adjust the clearance to make the linear bearing installation easier. The advantages of linear bushings include less tilt or friction, which results in less wear and better machining results over time.

When manufacture 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 bearing or SSW-OP super open linear bearing. Aluminum housing size range: length (L) ranges 38.1-120.65mm; width (W) ranges 50.8-152.4mm; height (F) ranges 28.7-91.96mm; minimum item SWD8 (supporting SW8OP open linear bearing or SSW8OP super open linear bearing), its combined size is 38.1*50.8*28.7mm, and the combined size of the largest specification SWD32 (supporting SW32OP open linear bearing or SSW32OP super open linear bearing) is 120.65*152.4*91.96mm. 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 10.31 mm, which can be easily and safely mounted to almost any linear motion system.

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