Aurora MB‑12 Rod End

The Aurora MB-12 is a high-quality precision rod end bearing from Aurora Bearing Co., part of their MB series of male-thread rod ends. It features a 0.750 in (¾″) bore, left-hand ¾-16 UNF male thread, steel housing with cadmium-type corrosion protection, and a precision alloy steel ball and race assembly.

Key Specifications

• Bore diameter: 0.750 in (¾″)

• Thread size: ¾-16 UNF male, left-hand (LH)

• Series: MB Series – Precision male rod end

• Construction: Low carbon steel housing (protective coated for corrosion resistance) and an alloy steel, heat-treated, chrome plated ball.

• Static radial load capacity: approximately 11,518 lbf (for MB-12) per published MB series data.

• Head diameter: 1.75 in; Head width: 0.687 in; Overall height: 3.75 in (per one listing)

• Misalignment angle: ~14° for the MB series rod end.

Features & Benefits

• Precision series design: Built to tighter tolerances than general-purpose rod ends, giving better motion control for scientific, instrumentation, or test equipment linkages.

• Left-hand thread: Useful when right-hand thread would loosen due to rotation or vibration; adds flexibility in machine design.

• Cadmium-plated steel + protective corrosion-coating: Enhances durability in industrial or laboratory environments.

• Large bore relative to thread size: ¾″ bore with ¾-16 thread provides robust load-carrying capacity while maintaining compact form.

• Suitable for motion linkages, articulating test rigs, fixture pivots, or industrial robot/automation joints.

Applications
Ideal for engineers, researchers, and institutions working in:

• Test systems and instrumentation linkages requiring precise motion articulation

• Laboratory equipment pivots, gimbals, or jig connections

• Industrial machinery where left-hand threaded link connections are needed

• Fixtures in optical, photonics, or vacuum setups where robust bearing articulation is required

• Retrofitting or servicing equipment where this rod end replaces a worn or under-spec linkage bearing
