Wheel Spacers

Matching Vehicle Hub and Bolt Specifications

Selecting the correct vehicle wheel spacer requires matching the Pitch Circle Diameter (PCD), center bore, and thickness to your specific fleet vehicles. Forged 6061-T6 aluminum spacers provide the high tensile strength needed for commercial applications. Ensure the spacer matches the exact bolt pattern, such as 5x120 mm for BMW E/F series or 5x112 mm for Mercedes-Benz, to prevent stud shear.

• Verify the Pitch Circle Diameter (PCD) and lug count, such as 5-lug 5x112 or 5x120.
• Select thicknesses from 12mm to 20mm to clear suspension components or brake calipers.
• Confirm center bore compatibility, such as 72.56mm or 66.6mm, for a direct hub fit.

Selecting Hub Centric Rings for Wheel Vibration Control

Hub centric rings bridge the gap between a vehicle's hub pilot and the wheel's center bore. Without these adapters, wheel load rests entirely on the lug studs, risking vibration and stud failure. Choose high-grade plastic rings for standard service or aluminum alloy rings for high-heat industrial fleet environments.

• Measure the wheel center bore for the outer diameter of the ring, such as 73.1mm or 82mm.
• Measure the vehicle hub pilot for the inner diameter of the ring, such as 57.1mm, 60.1mm, or 66.6mm.
• Use aluminum alloy adapters for heavy-duty applications where brake heat is high.

Specifying Hex Wheel Spacers for PCB Assemblies

For electronics manufacturing and MRO tasks, wheel spacers also refers to male-female hex standoffs used to mount motherboards and sub-assemblies. These components prevent electrical shorts by keeping PCBs separated from metal chassis. Choose the correct thread size and material to ensure mechanical stability.

• Thread sizes range from M2 to M6 for standard electronics enclosures.
• Select brass or copper materials for electrical conductivity and corrosion resistance.
• Use male-female hex configurations for stacking multiple boards in a single chassis.
