CuZn25Al5Mn4Fe3 Graphite Thrust Plates for Agitator Shaft Collars

Request a drawing-based CuZn25Al5Mn4Fe3 graphite-plugged thrust plate for an external agitator shaft collar where the assembly is designed with sliding axial support. The part has a flat working face, specified oil grooves and mounting holes. It is separate from the radial guide bearing and the process shaft seal.

Define the axial load path and the actual rubbing annulus
Identify which collar face rotates and which plate is fixed. Show the contact annulus, fixing-hole locations and shaft clearance. Give steady and reversing axial forces from the agitator, start-up torque and operating speed. A mounting hole or groove that crosses the contact area changes the working surface; copy neither pattern from a photograph without checking the collar drawing.
CuZn25Al5Mn4Fe3 is the requested high-tensile brass material. Specify the graphite layout independently from the groove profile and lubricant supply. A graphite-plugged face and an oil groove serve different lubrication functions. Confirm whether added oil or grease is intended, prohibited or required for commissioning. Do not use plain-alloy reference properties as a complete rating for this plugged and grooved bearing geometry.
Application boundaries to confirm
This enquiry is for the external mechanical support, not a wetted process part. Submit actual temperatures and any splash or vapour exposure. No chemical compatibility, sanitary or hazardous-area approval is implied. If the agitator can reverse thrust, show the support for both directions; a single plate must not be assumed to carry axial force from either side.
Dimensions and drawing-based quotation checklist
| Review item | Information required |
|---|---|
| Plate and collar | Bore/OD/thickness, collar annulus, flatness, parallelism and working-face finish. |
| Fixing and grooves | Hole coordinates, screw recesses, anti-rotation, groove section and feed connections. |
| Axial duty | Force directions, shaft speed, starts, thermal conditions and separate radial support. |
| Material and RFQ | Exact alloy/standard, graphite specification, lubricant plan, quantity and drawing revision. |
Send a dimensioned new-part drawing with units and revision, the mating-part dimensions and requested inspection documents. A worn sample is useful supporting evidence but may not preserve the original fit.
Installation and selection checks
Clean and support the mounting face, verify screw-head clearance and check collar runout. Set axial end float according to the assembly drawing rather than clamping the thrust face tightly. Confirm the radial bearing and seal do not impose unintended axial preload. Establish any specified lubricant feed before the agitator’s commissioning sequence.
Frequently asked questions
Does this plate also centre the shaft?
Its intended duty here is axial sliding support. Radial guidance requires a separately defined bearing arrangement.
Do the grooves automatically make it oil lubricated?
No. The feed source, lubricant and replenishment method must be specified and connected.
Can the illustrated plate be installed inside the process vessel?
That is a separate exposure and material-compatibility requirement. This enquiry concerns the external collar support.
