Bushing; ?12??16?L20; Q235A

Meet a precision-built bushing crafted from Q235A carbon structural steel, designed to handle demanding industrial tasks with consistent, dependable performance. With a compact footprint of 12 mm bore, 16 mm outer diameter, and a 20 mm length, this bushing fits neatly into pivot points, housings, and shaft assemblies where smooth motion and reliable load transfer matter most.

Why this bushing stands out

• 
  Material strength with practical machinability: Q235A combines solid load-bearing capacity with easy machining, delivering a durable pulley point, hinge, or slider component that resists deformation under typical operating pressures.
• 
  Precisely machined for dependable fit: The bore and outer diameter are finished to tight tolerances to promote consistent shaft alignment and repeatable performance across assemblies.
• 
  Versatile depth and footprint: Its compact 20 mm length makes it ideal for compact machinery, compact automation modules, and tight-engineered installations where space is at a premium.
• 
  Low-friction operation with proper lubrication: When paired with a suitable lubricant or grease, it supports smooth rotation, reduced wear, and longer service intervals in conveyors, robotics grippers, and motorized sliders.
• 
  Cost-effective yet dependable: A steel bushing option that balances strength, durability, and affordability for a wide range of mechanical applications.

Ideal uses and scenarios

Perfect for machinery builders, maintenance engineers, and DIY automation enthusiasts, this bushing excels in:

• Pivot joints and shaft collars in presses, lathes, and milling fixtures
• Low-to-mid load support in agricultural equipment, conveyors, and material-handling systems
• Robotics and automation assemblies requiring precise rotational play with robust steel backing
• Replacement bushings in housings where a standard 12 mm bore and 16 mm OD fit existing fittings

Practical tips for installation and longevity

• Ensure clean, undamaged bore surfaces before installation; any debris can affect alignment and wear.
• Choose matching lubrication or seizing prevention for long-term smooth operation; avoid dry running in environments with dust or grit.
• Confirm the outer diameter clearance in the housing to achieve a secure press-fit or lightly slotted/slip-fit as your design requires.
• Store and handle with care to prevent surface nicks that could alter performance in critical assemblies.
