Technical Specifications - AMES A-12-18-16

Specific permissible bearing pressure, sliding speed, operating temperature, mass, dimensional tolerances and lubricant characteristics should be confirmed against the documentation for the exact AMES material and product version.

These values should not be transferred from similar bushings without verification.

What Does AMES A-12-18-16 Mean?

The designation A-12-18-16 identifies the bushing construction and its three principal dimensions.

A - Cylindrical Bushing Series

The letter A identifies the cylindrical sleeve bushing series without an integral flange.

This design provides a compact sliding bearing surface for radial shaft support.

12 - Bore Diameter

The nominal internal diameter is 12 mm.

This is the surface intended to operate against the shaft.

18 - Outside Diameter

The nominal outside diameter is 18 mm.

This dimension is important when selecting the housing bore and the required mounting fit.

16 - Bushing Length

The nominal bushing length is 16 mm.

This dimension determines the axial length of the sliding bearing surface.

The complete designation therefore identifies a flangeless cylindrical bushing with nominal dimensions of 12x18x16 mm.

The designation does not contain additional suffixes defining a clearance class, precision class or special sealing configuration.

Construction of AMES A-12-18-16

Cylindrical Design Without a Flange

AMES A-12-18-16 has a straight cylindrical body without an integral flange.

Its main function is to provide radial support for a rotating or oscillating shaft.

Because it has no flange, axial shaft positioning must be provided by other suitable components in the mechanical assembly.

The bushing should not be treated as an independent axial locating or thrust bearing component.

Sintered Bronze Material

Sintered bronze is produced by compacting and sintering metal powder.

The manufacturing process creates a porous structure capable of retaining lubricating oil.

This structure allows the material to function both as a sliding bearing surface and as a lubricant reservoir.

The exact material properties depend on the bronze composition, porosity and manufacturing specification.

Internal Sliding Surface

The internal cylindrical surface operates directly against the shaft.

During operation, relative motion occurs through sliding contact rather than rolling contact.

The bushing does not contain balls, rollers or a cage.

Shaft surface finish, operating clearance, loading and lubrication conditions all influence friction and wear.

16 mm Bearing Length

The nominal length is 16 mm.

Bearing length affects the projected contact area and average bearing pressure under radial loading.

A longer bushing may provide a larger projected contact area, but it is not automatically interchangeable with a shorter version.

The available installation space and shaft alignment must also be considered.

How Does the Self-Lubricating Bushing Work?

The porous structure of sintered bronze can retain lubricating oil within the material.

During operation, oil can migrate toward the contact surface between the shaft and bushing.

Under suitable operating conditions, this lubricant helps reduce direct metal-to-metal contact and friction.

When the mechanism stops, some of the oil may return to the porous structure through capillary action.

This principle can reduce the need for periodic relubrication in appropriately designed applications.

However, self-lubricating operation does not mean unlimited operation without maintenance or lubrication.

The bearing must operate within the permissible limits of its material, lubricant and mechanical arrangement.

Radial Load Support and Projected Bearing Area

AMES A-12-18-16 is designed primarily for radial shaft support.

Radial forces are transmitted from the shaft through the internal sliding surface to the bushing and surrounding housing.

For a cylindrical plain bearing, the nominal projected bearing area is calculated using:

For AMES A-12-18-16:

The nominal projected bearing area is therefore 192 mm2.

This is a geometric value, not the permissible load capacity of the bushing.

The average projected bearing pressure can be estimated using:

Where:

• p - average projected bearing pressure

• F - applied radial load

• d - nominal bore diameter

• L - nominal bearing length

The permissible operating load must be determined using the manufacturer's material specifications, sliding speed limits, lubrication conditions and operating requirements.

AMES A-12-18-16 vs AMES A-12-18-15

Both designations identify cylindrical sleeve bushings with the same nominal bore and outside diameters.

Their main dimensional difference is length.

The 16 mm bushing has approximately 6.7% more nominal projected bearing area than the 15 mm version.

This does not automatically mean that its permissible load capacity is 6.7% higher.

Actual operating capacity also depends on the material characteristics, shaft alignment, lubrication and operating conditions.

The two variants are not automatically interchangeable because the 1 mm difference in length may affect the housing arrangement and shaft positioning.

Similar bushings from other manufacturers may share the same nominal dimensions.

However, identical dimensions do not guarantee equivalent material properties, dimensional tolerances, lubrication characteristics or operating limits.

AMES A-12-18-16 vs Flanged Bronze Bushings

The principal difference between a cylindrical sleeve bushing and a flanged bushing is the presence of an integral flange.

A flanged bushing may be appropriate when the mechanical design requires an additional axial contact surface.

AMES A-12-18-16 is a flangeless design and should not be described as a flanged bearing.

Selection and Interchangeability

Before purchasing AMES A-12-18-16, verify the following technical requirements.

1. Shaft Diameter

The nominal bore diameter is 12 mm.

The shaft tolerance must provide the required operating clearance.

2. Housing Bore

The nominal outside diameter is 18 mm.

The housing bore must be compatible with the recommended mounting interference.

3. Bushing Length

The nominal length is 16 mm.

Verify that the installation space and shaft support requirements are compatible with this dimension.

4. Mounting Fit

Press fitting can reduce the internal diameter of a porous bronze bushing.

The installed bore diameter must therefore be considered when selecting the shaft fit.

5. Operating Clearance

The required operating clearance depends on the shaft dimensions, bushing tolerances, mounting conditions and temperature.

6. Material Compatibility

A replacement bushing should have material characteristics appropriate for the application.

Different sintered bronze materials can have different load and wear characteristics.

7. Lubrication

Verify compatibility between the bushing material, impregnating oil and operating environment.

The lubricant type should not be assumed without manufacturer documentation.

8. Load and Sliding Speed

Evaluate the expected bearing pressure and sliding speed using the appropriate material limits.

9. Operating Temperature

Confirm that the temperature range is suitable for the specific bushing material and lubricant.

10. Type of Motion

Rotating and oscillating applications can impose different lubrication and wear requirements.

Important: Identical nominal dimensions of 12x18x16 mm do not automatically establish full interchangeability between products from different manufacturers.

Typical Applications of Sintered Bronze Sleeve Bearings

Cylindrical sintered bronze bushings are used as radial shaft support components in rotating and oscillating mechanisms.

Typical applications for this category of bearing include:

• Compact rotating shaft assemblies.

• Small drive mechanisms.

• Electromechanical equipment.

• Industrial mechanical assemblies.

• Shaft support and guidance mechanisms.

These are general applications of sintered bronze sleeve bearings.

They do not represent verified OEM applications for the specific AMES A-12-18-16 designation.

Suitability for a particular machine must be confirmed using the equipment design and operating requirements.

Installation and Maintenance

Surface Preparation

Clean the housing bore, shaft and bushing before installation.

All surfaces should be free from contamination and mechanical damage.

Press Fitting

Press the bushing evenly into the housing using an appropriate installation tool.

Avoid misalignment and excessive mounting force that could deform the bushing.

Checking the Installed Bore

The interference fit can change the internal diameter of the bushing.

Check the required shaft clearance after installation and before starting the mechanism.

Protecting the Porous Structure

Avoid unnecessary machining or surface treatment that could damage or close the pores of the sintered bronze.

Any additional finishing operation should be compatible with the manufacturer's recommendations.

Lubrication

Use lubricants suitable for the bushing material and its existing oil impregnation.

Do not assume that all sintered bronze bushings use the same lubricant.

Storage

Store the bushing in a clean, dry environment.

Protect it against contamination, corrosion and unnecessary loss of impregnating oil.
