Atlas Axle Sleeve 2009496 High Quality Spare Parts for air Compressors

An Axle Sleeve, also commonly known as an Axle Bushing or Bearing Sleeve, is a cylindrical component designed to fit snugly between an axle or shaft and its surrounding housing, bore, or bearing. It acts as a protective interface, reducing friction, absorbing radial loads, and facilitating smooth rotational or linear movement. Axle sleeves are critical for alignment, wear resistance, and simplifying assembly and maintenance in mechanical systems.

The primary function of an axle sleeve is to protect and interface. Its specific purposes include:

• Wear Reduction: Provides a sacrificial surface that wears instead of the more expensive axle or housing, extending the lifespan of the entire assembly.
• Friction Management: Creates a low-friction surface for the axle to rotate or slide against, improving efficiency.
• Load Distribution: Helps distribute radial loads evenly across the housing, preventing stress concentration and deformation.
• Alignment & Positioning: Ensures the axle remains precisely centered and aligned within its housing.
• Corrosion Prevention: Acts as a barrier, protecting the axle from galvanic corrosion or seizing within the housing.
• Simplified Maintenance: Allows for easy replacement during overhaul without machining the larger components.

An axle sleeve operates as a stationary or semi-stationary liner:

1. Installation: The sleeve is pressed or slid into the housing bore. The axle or shaft is then inserted through the inner diameter of the sleeve.
2. Interface: The inner surface of the sleeve interfaces with the rotating or sliding axle.
3. Load Transfer: Radial forces from the axle are transferred through the sleeve to the housing.
4. Friction Control: The sleeve material, often self-lubricating or used with grease, minimizes friction and heat generation.
5. Wear Absorption: Over time, the sleeve experiences wear. It is designed to be replaced much more easily and cheaply than the axle or housing.

• Dimensions: Inner Diameter (ID) (fits the axle), Outer Diameter (OD) (fits the housing), Length (L).
• Material: Bronze (oil-impregnated or solid), Cast Iron, Sintered Steel, Bearing Steel, Plastics (PTFE, Nylon, UHMW), Stainless Steel.
• Tolerance: Precision machined to tight tolerances (e.g., H7/g6 fit) for proper clearance or interference.
• Hardness: Often heat-treated to a specific surface hardness (e.g., Rockwell C) to resist wear.
• Surface Finish: A smooth internal finish (e.g., 16-32 µin Ra) is critical for low friction.

Axle sleeves are ubiquitous in machinery across all sectors:

• Automotive: In suspension systems (e.g., control arm bushings), steering linkages, and transmission idler gears.
• Agriculture: In tractor pivot points, combine harvesters, and implement linkages.
• Construction & Mining: In excavator boom joints, conveyor rollers, and track systems.
• Industrial Manufacturing: As guides for linear motion shafts, in gearboxes, and on conveyor systems.
