INTRODUCTION
Tapered Roller Bearings Structure
Tapered roller bearings are designed to support combined radial and axial loads. Their load capacity depends on the contact angle—the larger the angle, the higher the axial load capacity.

TRB Components
The Cup
(Outer Ring)
- Material: Premium high-carbon chromium steel.
- Design: Separable structure for independent mounting.
- Benefit: High fatigue life and easy interchangeability.
The Cone
(Inner Ring)
- Structure: Separable from the outer ring assembly.
- Mounting: Engineered for a precise shaft fit.
- Function: Transfers combined radial and axial forces.
Tapered
Rollers
- Geometry: Optimized logarithmic roller profile.
- Performance: Ensures uniform load distribution.
- Function: Reduces edge stress and premature pitting.
The Cage
(Retainer)
- Steel Option: Suitable for heavy-duty loads.
- Polymer Option: Ideal for high-speed, low-noise use.
- Brass Option: Helps reduce friction and heat generation.

Premium Bearing Steel
Material Options: 100Cr6, 52100, GCr15, GCr15SiMn, Case-hardened Steel G20Cr2Ni4A, etc.
Manufactured with high-purity chrome steel. Our advanced heat treatment process achieves a hardness of 60-64 HRC, extending operational lifespan by up to 35% compared to standard market alternatives.

High Precision Grades
Precision Grade: P5, P4, P2, ABEC-1 to ABEC-7.
Strict quality control guarantees dimensional accuracy. Runout tolerance is controlled within 0.003mm, ensuring smooth rotation at high speeds up to 8,000 RPM with significantly reduced vibration and noise.

Optimized Heavy Load Capacity
Logarithmic profile on rollers and raceways.
Logarithmic internal profiling reduces edge stress accumulation. Dynamic load rating (Cor) is enhanced by 15%, perfectly supporting extreme radial and axial combined loads in heavy-duty applications.

Advanced Heat Treatment
Through-hardened & Case-hardened.
Optimized quenching and tempering processes ensure maximum surface hardness and core toughness. This significantly boosts wear resistance and extends the service life even under heavy shock loads.

Rigorous Quality Inspection
Dimensional Consistency Inspection
Equipped with advanced testing facilities like CMM and roundness testers, we closely monitor critical production stages. Our comprehensive quality control system ensures consistent precision and strict adherence to industry tolerances.
