Iron-Copper Sintered Bushings
SAE 863 iron-copper bushings for industrial equipment, standard or custom.
SAE 863 Iron-Copper Bearing Material
SAE 863 is an iron-copper grade used for powder metallurgy bearings. Confirm the material composition and the finished bearing properties against the applicable material specification and product data.
Sintered metal is porous, a structure formed during powder metallurgy. Where the grade and the process allow oil impregnation, the pores hold lubricant and release it during operation.
Purchasing and engineering teams need more than the material name. The grade, the oil impregnation condition, the finished dimensions and the operating requirements all have to match the application.

Send GLARY your material requirements and we will share the technical documentation available for your evaluation.
Available Sintered Bushing Designs
The bushing design has to suit the housing, the shaft and the space available for installation. GLARY checks the structure against our manufacturing capabilities once we have your drawing.
| Design detail | Information to confirm |
|---|---|
| Cylindrical sleeve bushing | Inner diameter, outer diameter and length |
| Flanged bushing | Flange diameter, flange thickness and overall length, if available |
| Other powder metal components | Shape and drawing requirements, subject to manufacturing review |
| Standard dimensions | Check the available size range with GLARY |
| Drawing-based production | Submit a 2D drawing or 3D file for review |
If you are replacing an existing bushing, a drawing or a sample with measured dimensions reduces the chance of a specification error.
Operating Conditions and Lubrication
Whether an SAE 863 bushing suits your application depends on the actual load, sliding speed, temperature, lubrication and shaft condition. A material grade on its own does not set the allowable operating limits of the finished component.
Before selecting a bushing, confirm the following:
- Load: radial load, and any impact or fluctuating load during operation.
- Speed and movement: continuous rotation, intermittent rotation or oscillating movement.
- Lubrication: whether the bushing is oil-impregnated, needs additional lubrication, or runs under another specified arrangement.
- Temperature: normal operating temperature and any short-term peaks.
- Shaft condition: shaft material, hardness, surface finish and dimensional tolerance.
- Service requirements: expected service life, maintenance interval and replacement frequency.
Include these conditions with your drawing and material requirements. Take allowable load, speed and temperature values from verified product data and check them against the actual application.
Applications of SAE 863 Iron-Copper Bushings
SAE 863 iron-copper sintered bushings are an option for mechanical assemblies where the material properties, the bearing structure and the lubrication arrangement meet the operating requirements.
Agricultural machinery is one area to consider, though not every pivot, linkage or shaft position needs the same bushing material. The right choice depends on the actual load, movement, lubrication and contamination.
Agricultural Machinery
Combine harvesters
Combine harvesters contain pivoting joints and rotating mechanisms in areas such as header linkages, reel mechanisms and other moving assemblies. The bushing you need depends on the specific position, load, speed and lubrication arrangement.
For a broader view of bushing positions and selection, see our Combine Harvester Bushings page.
Tractors
Tractors use bushings in linkage joints, steering assemblies, axle pivots and hydraulic cylinder mounts. These positions can see repeated oscillation, shock loads, vibration and outdoor contamination.
Consider SAE 863 only where its verified material properties and lubrication characteristics match the joint. For other material options and application requirements, visit our Tractor Bushings page.
Other Industrial Applications
SAE 863 can also be evaluated for other mechanical assemblies where the material and the finished bearing meet the required operating conditions. Tell us the equipment type and the bushing position so we can assess the specification against the actual application.
Dimensions and Custom Manufacturing
With sintered bushings, dimensional compatibility matters as much as the material grade. A bushing with the correct material designation but the wrong fit or length may not perform as required.
GLARY can check standard-size requirements and drawing-based requests. Include the following dimensions and tolerances in your inquiry.
| Required information | Details |
|---|---|
| Inner diameter (ID) | Finished bore diameter and tolerance |
| Outer diameter (OD) | Housing fit and outside diameter tolerance |
| Length | Overall bushing length |
| Flange dimensions | Required only for flanged designs |
| Material | SAE 863 or the grade specified in your drawing |
| Lubrication condition | Oil impregnation or other specified requirement |
| Quantity | Prototype, trial order or production quantity |
| Drawing / sample | 2D drawing, 3D file or sample dimensions |
For repeat orders, add any existing part number, revision level and inspection requirements. They keep the material and the dimensions consistent between orders.
SAE 863 Sintered Bushings for OEM and Replacement Orders
GLARY reviews inquiries for standard-size bushings and components made to customer drawings, subject to specification and manufacturing review.
For OEM projects, send the drawing, the target quantity and the expected production schedule. For replacement parts, send the original part number where you have it, along with the measured dimensions and the operating conditions.
Before production, confirm the material grade, dimensions, tolerances and lubrication requirements against the agreed specification.
To request a quotation, send GLARY:
- Material grade and required product design
- Inner diameter, outer diameter and length

Frequently Asked Questions
What is the difference between SAE 863 and SAE 841 bushings?
SAE 863 is an iron-copper powder metallurgy bearing material, while SAE 841 is commonly associated with oil-impregnated sintered bronze bearings. Their material composition and performance characteristics differ, so they should not be treated as direct substitutes without checking the application requirements.
Can SAE 863 bushings replace an existing iron or bronze bushing?
A replacement should be evaluated against the original material, dimensions, shaft and housing fits, load, speed and lubrication requirements. Matching the dimensions alone does not confirm that a different material will perform correctly.
Are SAE 863 bushings suitable for oscillating movement?
Suitability depends on the oscillation angle, frequency, load, lubrication condition and required service life. Provide these details when evaluating SAE 863 for a pivot or linkage joint, particularly in agricultural machinery.
What should be checked when switching to SAE 863 bushings?
Confirm the material specification, finished dimensions, shaft and housing fits, lubrication requirements and operating limits. If the change is intended to reduce wear or maintenance, compare the existing bushing's failure mode and working conditions before selecting a replacement.
