Product Overview
C3056 carb toroidal roller apply to machine tool spindle, dither motor, gas turbine, Centrifugal machine, minicar front wheel, reducer, pinion shaft, instrumentation and so on.
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.

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. Cage material for this reference is Brass/Bakelite/Nylon/Steel.

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.
