Double row tapered roller bearings are widely used in automotive axles, gearboxes, rolling mills, construction machinery, and heavy industrial equipment. Thanks to their ability to simultaneously support high radial loads and bidirectional axial loads, they ensure stable operation under heavy load and impact conditions.
The double row structure provides enhanced rigidity and improved load distribution, reducing shaft deflection and extending service life. These bearings perform reliably in high-load, high-vibration, and demanding operating environments, helping equipment maintain accuracy, reduce downtime, and improve overall operational efficiency.
FAQ
Q1: What are double row tapered roller bearings mainly used for?
A: They are commonly used in automotive axles, gearboxes, construction machinery, rolling mills, and heavy-duty industrial equipment, where high radial loads and axial loads in both directions are required.Q2: What are the advantages of double row tapered roller bearings compared to single row types?
A: Double row designs offer higher load capacity, better rigidity, and improved shaft alignment, making them more suitable for heavy loads, impact loads, and high-precision applications.Q3: Can double row tapered roller bearings handle axial loads in both directions?
A: Yes. The double row structure allows the bearing to support axial loads from both directions simultaneously, improving operational stability.Q4: Are these bearings suitable for high-speed applications?
A: They are primarily designed for medium to high loads rather than extremely high speeds. With proper lubrication and installation, they can operate reliably in moderate-speed applications.Q5: Do you provide OEM or customized solutions?
A: Yes. We offer OEM/ODM services, including custom dimensions, tolerances, materials, cages, and packaging, to meet specific application requirements.
