Product Overview
89372 M Cylindrical roller thrust bearings are suitable for arrangements that have to support heavy axial loads.
Furthermore, 89372 M Cylindrical roller thrust bearings are relatively insensitive to shock loads, are very stiff and require little axial space.
As standard they are available as single direction bearings and can only accommodate axial loads acting in one direction.
Bearing Number: 81101-81196 81200-81272 89306-89372 89408-89432 Application: 89372 M bearing is used to Automobile, tractor, machine tool, electric machine, water pump, agricultural machinery and textile machinery.
Key Benefits
- Thrust roller bearings carry a much higher axial load in the same envelope than a thrust ball bearing of the same size, and the tapered thrust design can add up to 40 percent more capacity than cylindrical and spherical bearings with the same envelope dimensions.
- 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
Rolling mill rebuilders, plastic extruder OEMs, drilling equipment shops, pulp and paper maintenance teams.
Problems It Solves
Standard catalogue thrust bearings are often out of stock in large bores, and the imperial TP and T series used on older mill and extruder equipment are hard to source from a single supplier.
Specifications
Recorded Specification
Every row below comes from the manufacturing record for this reference. Rows that were never filled in are omitted rather than guessed.
| Product Name | 89372 M Cylindrical roller thrust bearings |
|---|---|
| Brand | AFA |
| Material | GCr15, GCr15SiMn, chrome steel |
| Precision Class | P0 P6 P5 P4 P2 |
Application Scenarios
Where It Is Used
- Rolling mill stands and screw-down units
- Plastic extruders and rubber machinery
- Oil well swivels and rotary tables
- Pulp refiners and paper machinery
- Machine tool tables and vertical spindles
Materials
GCr15, GCr15SiMn, chrome steel. 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 ISO 9001 quality assurance system. Certificate copies for a specific consignment are issued with the shipping documents on request.
Customization Options
What Can Be Changed
| Precision class | P0 P6 P5 P4 P2 |
|---|---|
| Cage material | Brass, steel, bakelite or nylon by application |
| Internal clearance | Standard or a specified group |
| Marking | AFA brand, neutral, or customer marking |
| Packing | Wood boxes or paper boxes |

| Thrust roller | None | Very high | Low to medium |
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.
