Special And Non Standard Bearings
5313 Spiral Roller Bearing
5313 Flexible Roller Bearing
CAD files are available on request through WhatsApp or email rather than as a public download.
Product Overview
5313 Spiral roller bearings automatically compensate for play in high temperature environments.
5313 Spiral roller bearings resist shock and continue to work under flexural deformation.
5313 Spiral roller bearings are ideal for use in steel mill continuous casting and rolling mills and high temperature transmission equipment.
Key Benefits
- The group has produced non standard and specially required bearings alongside its catalogue range since 1995, so a drawing or a sample can be quoted directly.
- 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
Conveyor and bulk handling engineers, turbine service companies, machine designers working to a drawing rather than a catalogue.
Problems It Solves
When the envelope is fixed by an existing machine, a catalogue part simply does not exist and the buyer has to find a factory willing to make one bearing rather than a pallet of them.

Application Scenarios
Where It Is Used
- Conveyor and bulk handling drives
- Turbine and hydrogen turbine assemblies
- Robotics and rotary indexing tables
- Medical and semiconductor equipment
- Retrofit and legacy machine repair
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 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.
