Double Row tapered roller bearing

Double row tapered roller bearing, the bearing has one outer ring and two inner rings, and there is a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer. It can bear radial load and bidirectional axial load at the same time. Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry, e.g. tunnelling machines.

Category Overview

Tapered Roller Bearings are separable rolling element bearings designed to withstand combined radial and axial loads simultaneously. Featuring tapered inner and outer raceways and tapered rollers, these bearings offer high load capacity, high rigidity, and precise axial positioning, making them ideal for applications requiring heavy loads, impact resistance, and accurate shaft alignment.Our tapered roller bearing range covers single-row, double-row, and four-row configurations, with metric and inch sizes available, suitable for automotive, industrial machinery, mining, metallurgy, and other heavy-duty industries.

Our Series Breakdown

We provide a full range of tapered roller bearing series to meet diverse load, speed, and application requirements:

Series	Configuration	Key Features	Typical Applications
30200 Series	Single Row	Standard design, medium load capacity, cost-effective	Automotive wheel hubs, gearboxes, small reducers
30300 Series	Single Row	Medium-heavy load, high rigidity, wide application	Industrial gearboxes, agricultural machinery, construction equipment
32200 Series	Single Row	Thickened section, enhanced radial load capacity	Truck axles, heavy gearboxes, mining machinery
32300 Series	Single Row	Heavy-duty design, maximum radial/axial load capacity	Large reducers, crushers, construction machinery
31300 Series	Single Row	Large contact angle, high axial load capacity	Pump units, compressors, high-thrust applications
33000/33100/33200 Series	Single Row	Compact structure, automotive-optimized	Passenger car/hub bearings, differential gears
Double Row Tapered Roller Bearings	Double Row	High combined load capacity, self-aligning option	Heavy gearboxes, rolling mills, crane wheels
Four Row Tapered Roller Bearings	Four Row	Ultra-high load capacity, separable design	Cold/hot rolling mills, heavy industrial equipment

Core Advantages

High Combined Load Capacity: Effectively bear heavy radial loads and bidirectional axial loads simultaneously.
Separable Design: Inner and outer rings can be installed separately, simplifying assembly and disassembly.
High Rigidity & Impact Resistance: Suitable for harsh working conditions with shock loads and vibration.
Precise Axial Positioning: Accurately control shaft axial play, ideal for precision transmission systems.
Wide Compatibility: Available in multiple series and sizes, covering automotive, industrial, and heavy machinery applications.

Typical Industrial Applications

Widely used in automotive wheel hubs, gearboxes, reducers, mining equipment, crushers, rolling mills, agricultural machinery, construction machinery, pumps, compressors, and other heavy-duty mechanical transmission systems.
