Single row Taper Roller Bearings

SYSTEM DESCRIPTION:

I. Product Positioning
Single Row Taper Roller Bearings are a core product series from Ningbo Sanya Bearing Co., Ltd., a professional manufacturer established in 1994. This product is specifically designed for heavy-duty industrial and automotive applications that require handling extremely high loads and strict mechanical rigidity.

II. Core Structure and Working Principle

Tapered Roller Design: The bearing consists of an inner ring, an outer ring, and tapered rollers. The contact geometry between the rolling elements and the raceways ensures pure rolling motion.
Composite Load Handling: Unlike bearings that primarily handle radial forces, single row taper roller bearings are engineered to simultaneously accommodate massive radial loads and heavy axial loads in one direction.
Separable Structure: These bearings typically feature a separable design, meaning the inner ring assembly (cone) and the outer ring (cup) can be installed independently, greatly simplifying mechanical assembly and maintenance processes.

III. Performance Advantages and Applications

High Rigidity and Long Service Life: Due to their linear contact characteristics, these bearings exhibit minimal deformation under heavy loads, significantly enhancing the operational precision of the shaft system.
Paired Installation Flexibility: Similar to angular contact ball bearings, single row taper roller bearings are often installed in pairs or in an opposed arrangement to accommodate axial forces from opposite directions and to adjust internal clearance.
Wide Range of Applications: They are widely utilized in automotive wheel hubs, transmissions, gear reducers, and various types of heavy construction machinery.

IV. Manufacturing Assurance and International Standards

Lean Production: Ningbo Sanya Bearing utilizes highly-automated equipment and comprehensive testing methods to ensure consistent product quality.
Rigorous Certification: The company is ISO9001 certified and introduced the ISO/TS16949 quality management system in 2017. This ensures that production processes meet high global automotive industry standards, providing customers with high-precision, long-life solutions.
Global Vision: With over 20 years of export experience, the company’s products are sold in more than 50 countries and regions. Guided by the goal to “get the world move with Chinese Bearings,” they offer cost-effective solutions to global clients.

TECHNICAL DRAWING:

Single row tapered roller bearings are designed to accommodate
combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°.
