6–8 mm Hole Bush (Reducer Bush / Sleeve)

A 6–8 mm hole bush is a small cylindrical metal component designed to act as a reducer or spacer between two parts with different hole diameters. It typically allows a smaller shaft, bolt, or pin (≈6 mm) to fit securely inside a larger hole (≈8 mm).

It is commonly used in mechanical assemblies to improve alignment, reduce wear, and ensure proper fitment between mating parts. The bush may include cross holes for lubrication, locking pins, or fastening.

Technical Specifications:

• Type: Reducer bush / sleeve bush
• Inner Diameter (ID): ~6 mm
• Outer Diameter (OD): ~8 mm
• Length: Typically 10–25 mm

Features:

• Size reduction: Converts larger holes to smaller usable diameters
• Improved alignment: Ensures concentric positioning of shafts or fasteners
• Wear resistance: Protects main components from friction damage
• Easy installation: Press-fit or slip-fit design
• Versatility: Can be used with bolts, pins, or rotating shafts
• Lubrication support: Cross holes allow grease or oil flow
• Corrosion resistance: Depending on material/finish

Applications:

• Automotive assemblies (linkages, pivots, suspension parts)
• Machinery & equipment (shaft alignment, bearing spacing)
• Fabrication & structural work (hole size adaptation)
• Bicycles & small mechanical systems (axle or pivot adjustments)
• Fastener systems (reducing bolt hole sizes)
• Maintenance & repair (retrofitting mismatched components)
