Product Overview
Floating Labyrinth Seals 3AFP9901203 is listed in the oil seals and rotary shaft seals range. Oil seals retain lubricants and fluids around an oscillating, rotating or reciprocating shaft and keep out the contaminants that destroy the internal components behind them.
Key Benefits
- Oil seals retain lubricants and fluids around an oscillating, rotating or reciprocating shaft and keep out the contaminants that destroy the internal components behind them.
- Dimensions, material, cage and precision class are confirmed in writing before the order is placed.
- Stock and produced lines are quoted separately so a shutdown can be planned around real dates.
- Non standard sizes can be made to drawing, so a fixed machine envelope is not a dead end.
Who It Is For
Engine rebuilders, mining and quarry maintenance teams, heavy truck and excavator part distributors.
Problems It Solves
A sealing failure usually stops the machine, and the replacement often has to match a legacy dimension that no longer appears in current seal catalogues.

Application Scenarios
Where It Is Used
- Engines, gearboxes and axles
- Excavator and dozer final drives
- Mining crushers and conveyors
- Wheel hubs and truck axles
- Pumps, compressors and hydraulic cylinders
Materials
alloy, brass, steel or other. GCr15 is the standard high carbon chrome bearing steel, and GCr15SiMn adds silicon and manganese so that larger rings harden through the section. Case carburised grades are used where shock loading is high.

Manufacturing Process
How It Is Made
Forging And Turning
Rings are formed and soft turned to the ring geometry.
Heat Treatment
Through hardening or carburising to the working hardness range.
Grinding And Honing
Raceways and faces ground to the tolerance class ordered.
Assembly And Preservation
Rolling elements and cage assembled, then preserved and packed.
Quality Control
What Is Checked
- Bore, outside diameter and width against the tolerance class ordered
- Radial and axial runout on the finished assembly
- Hardness and surface finish after grinding
- Internal clearance and rotation check before preservation
Certifications. Production runs in strict accordance with the ISO9001:2008 standard. Certificate copies for a specific consignment are issued with the shipping documents on request.

Use Guide
Fitting And Service Notes
- Check the shaft and housing seats for size, roundness and damage before opening the packaging.
- Push mounting force through the ring that carries the interference fit, never through the rolling elements.
- Where heat mounting is used, keep the bearing below roughly 120 degrees Celsius and never apply a flame.
- Set clearance or preload as the machine drawing specifies, then fill with the specified lubricant.
- Turn the assembly by hand and listen before the machine is started.
