Product Overview
SL Cylinder roller bearing is listed in the sl full complement cylindrical roller bearings range. Filling the whole annulus with rollers gives the highest radial rating available in the section, with the trade off of a lower limiting speed.
Key Benefits
- Filling the whole annulus with rollers gives the highest radial rating available in the section, with the trade off of a lower limiting speed.
- 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
Gearbox designers and rebuilders working to a fixed envelope where a caged bearing no longer carries the load.
Problems It Solves
Removing the cage raises capacity but narrows the supply base, and SL series parts are often quoted at OEM lead times.
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 | SL Cylinder roller bearing |
|---|---|
| Brand | AFA |
| Material | GCr15, GCr15SiMn, chrome steel |
| Precision Class | P0 P6 P5 P4 P2 |
Application Scenarios
Where It Is Used
- Planetary and industrial gearboxes
- Rolling mill and crusher drives
- Wind turbine gear stages
- Machine tool feed drives
- Heavy press equipment
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 |
| Non standard sizes | Made to drawing or to a sample |
Comparison
How This Type Compares
| Type | Radial load | Axial load | Speed |
|---|---|---|---|
| Deep groove ball | Medium | Low | High |
| Angular contact ball | Medium | High one way | High |
| Cylindrical roller | High | None or located | High |
| Tapered roller | High | High one way | Medium |
| Needle roller | High for section | None | Medium |
| 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.
