Precision Shaft Support

The Unique-Bargains SK12 is an aluminum linear-rail shaft support designed for 12 mm diameter shafts. Each package contains two supports machined from corrosion-resistant aluminum for long service life in precision machinery.

Suited for Metric Linear Systems

This part fits builders assembling equipment that uses 12 mm round rails with a 32 mm mounting-hole pitch and 5.5 mm hole diameter. Projects based on different shaft diameters or mounting patterns cannot use these supports.

Critical Mounting Specification

The fixed 32 mm centre-to-centre hole spacing and 5.5 mm hole diameter determine whether the SK12 aligns with your existing rail base. Verify those dimensions before ordering.

Questions about this item

What does the 12 mm shaft diameter mean for my linear rail setup?

The SK12 support is machined for a 12 mm shaft, so it matches standard 12 mm linear rods and keeps the rail centred without play.

How do the 5.5 mm mount holes and 32 mm spacing limit my mounting options?

You need two M5 bolts on a 32 mm pitch; the pattern fixes the support to any flat surface with matching holes.

Will the 42 × 14 × 38 mm body clear my machine frame?

The block measures 42 mm long, 14 mm wide and 38 mm high, so check those envelopes against your frame before ordering.
