Introduction
Tapered Roller Bearing Structure and Components
Tapered roller bearings are designed to support combined radial and axial loads. Their axial load capacity is influenced by the contact angle — a larger contact angle generally provides higher axial load carrying capability.

TRB Components
The Cup
(Outer Ring)
- Material: Premium high-carbon chromium bearing steel.
- Design: Separable outer ring for flexible assembly and mounting.
- Benefit: Supports interchangeability and long fatigue life.
The Cone
(Inner Ring)
- Structure: Inner ring assembly with rollers and cage.
- Mounting: Designed for accurate shaft fitting and alignment.
- Function: Transfers combined radial and axial forces.
Tapered
Rollers
- Geometry: Optimized tapered or logarithmic roller profile.
- Performance: Helps distribute load more evenly across the raceway.
- Function: Reduces edge stress and improves running stability.
The Cage
(Retainer)
- Steel Option: Suitable for general and heavy-duty operating conditions.
- Polymer Option: Available for selected low-noise or high-speed applications.
- Brass Option: Helps improve strength, stability, and heat resistance.

Why Choose Us?
TEDIN supplies standard and custom tapered roller bearings for heavy-duty equipment, precision machinery, and OEM projects. From material selection to heat treatment, precision grinding, and final inspection, we focus on reliable performance under combined radial and axial loads.

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.

Tailored Custom Solutions
Customized Structures and dimensions.
Beyond standard sizes, our experienced engineering team excels at developing non-standard bearings for specific industrial applications. We offer fast-turnaround OEM & ODM services to match your unique project needs.
