Product overview

Bearing Bush for Rotary Kiln Support Rollers

As the kiln rotates, friction between the kiln tyre and support roller turns the roller while its journal is carried by the bearing bush. The bush therefore supports reaction force and component weight together with dynamic and impact loads.

AGICO manufactures rotary kiln bearing bushes, copper bushes, bushings and pads to customer requirements. Aluminum bronze is the traditional wear-resistant choice; zinc-alloy bearing bushes can be evaluated for medium- and low-speed heavy-load applications where heat transfer, weight and cost are important.

Materials and Construction

01

Aluminum Bronze

The original page highlights mechanical strength, wear and corrosion resistance, casting performance, compact structure and resistance to brazing.

02

Zinc Alloy

An alternative with low friction, high thermal conductivity and good machinability for suitable medium- and low-speed heavy-load duties.

03

Application-Based Choice

Material selection must consider journal load, speed, lubrication, temperature, environment, housing fit and the buyer's approved specification.

Function in the plant

How the Bearing Bush Works

The Bearing Bush transmits or supports operating load through rotating and stationary interfaces. Its performance cannot be judged by outside dimensions alone. Load path, mating parts, operating environment and the condition of the surrounding equipment all affect whether a replacement will fit correctly and run reliably. AGICO therefore reviews the component as part of the machine rather than treating it as an isolated catalogue item.

For a replacement project, the most useful starting point is the current drawing together with the equipment model and site observations. Wear photographs, failure location, maintenance history and measurements taken during shutdown help distinguish normal consumption from an interface, alignment or operating problem. This review allows the quotation to state the proposed supply boundary and the information that still requires confirmation.

Engineering selection

Bearing Bush Selection Criteria

Confirming the following groups of data reduces dimensional risk and avoids selecting the Bearing Bush from a name or model reference alone.

01

Applied radial, axial and transient loads

Provide the available values, drawing references and photographs for applied radial, axial and transient loads. AGICO will compare them with the proposed Bearing Bush configuration and identify any missing inputs before the manufacturing basis is released.

02

Operating speed, direction and duty cycle

Where site data differs from an old drawing, mark the measured value and the measurement position. The final requirement should be agreed against the approved drawing rather than assumed from a nominal equipment designation.

03

Mating diameters, fits, datums and bolt pattern

Provide the available values, drawing references and photographs for mating diameters, fits, datums and bolt pattern. AGICO will compare them with the proposed Bearing Bush configuration and identify any missing inputs before the manufacturing basis is released.

Controlled production

Manufacturing and Inspection Route

The production route for the Bearing Bush is established after drawing review. It typically coordinates casting or forging route, heat treatment and rough machining. Process hold points depend on material, geometry and the buyer's inspection requirements. Critical datums and machining references are identified early so that later operations protect the interfaces used during installation.

Inspection is planned around product risk rather than added only at final dispatch. Material traceability and heat-treatment records; Critical journals, bores, faces and runout; Specified NDT at highly stressed transitions; Balance, contact pattern or assembly checks when applicable. When a test or report is required, it should be listed in the enquiry so that sampling, acceptance criteria and document format can be agreed before manufacture. Final release checks also confirm marking, quantity, surface protection and the packing list.

Plan the shutdown

Inspection and Replacement Indicators

Maintenance teams should evaluate the Bearing Bush together with its mating parts and operating records. Typical reasons for closer inspection include:

Unusual vibration, noise or temperature near the component. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.

Cracks, scoring, fretting or uneven contact marks. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.

Loss of alignment, excessive runout or repeated seal failure. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.

Dimension drift that prevents a controlled fit during shutdown. Record the location, extent and operating condition, then compare the finding with the equipment maker's limits and the site's maintenance procedure before deciding whether repair or replacement is appropriate.

From drawing to site

Custom Supply, Packing and Worldwide Delivery

AGICO can prepare a drawing-based Bearing Bush for new supply or replacement service. The technical review covers the requested material, configuration, interfaces, inspection scope and documentation. If the original drawing is incomplete, provide measurements, nameplate information and clear photographs; the missing points will be listed for confirmation. No order-dependent dimension or performance value is treated as final until it appears in the approved technical documents.

Packing is planned for component weight, geometry, transport mode and destination. Finished surfaces can be protected against handling damage and corrosion, while loose accessories and documents are identified against the packing list. For international delivery, buyers should state the destination, preferred trade terms, lifting or site-access restrictions and required arrival schedule so that the quotation can separate manufacturing scope from freight and local handling.

Buyer questions

Frequently Asked Questions

Which material should I choose for a rotary kiln bearing bush?

Aluminum bronze and zinc alloy are both available references. Selection depends on load, speed, lubrication, temperature, mating surfaces and project specification.

What causes a bearing bush to run hot?

Possible causes include incorrect clearance, poor lubrication, misalignment, abnormal thrust contact, excessive load or damaged mating surfaces. Diagnose the system before replacement.

What does the original 45°C value mean?

The original page advises an on-site check when the tile or oil-pool temperature exceeds 45°C; it is a troubleshooting reference, not a universal alarm limit.

Can AGICO machine oil grooves and split-bush features?

Yes. Provide the approved drawing, groove layout, split arrangement, tolerances and mating-part data for manufacturing review.
