Product Overview
Аксиалните конусни ролкови лагери TRTB311 се състоят от две аксиални колела, набор от ролки и клетка.
Аксиалните конусно-ролкови лагери TRTB311 този дизайн може да създаде до 40 процента повече капацитет от цилиндрични и сферични лагери със същите размери на обвивката.
Приложение: Аксиалните конусно-ролкови лагери TRTB311 се прилагат за машинни инструменти, стойки за мелници, въртящи се маслени кладенци, пластмасови екструдери, рафинери за целулоза и т.н.
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.

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, хромирана стомана. 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.

| 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.
