E Series Self-Aligning Roller BearingsSelf-aligning roller bearings

Type E self-aligning roller bearings are high-performance, heavy-duty bearings featuring an optimized design. They incorporate precision-engineered symmetrical barrel-shaped rollers and reinforced stamped steel cages. The internal structure has been spatially optimized, with both the size and number of rollers increased to provide load-carrying capacity and operational stability far exceeding those of standard models. This series of bearings retains excellent self-aligning performance, effectively compensating for misalignment errors during equipment installation and shaft deflection during operation. They can simultaneously withstand large radial loads and bidirectional axial loads, while offering lower friction losses and better heat dissipation. The applicable speed range has also been significantly increased, combining high strength and rigidity with excellent resistance to impact and vibration. With a compact and durable design and optimized lubrication channels—some models even feature oil grooves and oil holes to enhance lubrication—these bearings are well-suited for complex and harsh operating conditions such as humidity, dust, heavy loads, and vibration. Compared to traditional CC-type bearings, they offer significant improvements in load-carrying capacity and service life, while also being more cost-effective and better suited for high-speed applications than CA-type bearings with brass cages. They are widely used in various heavy-duty rotating mechanisms, including mining machinery, metallurgical equipment, heavy-duty fans, gear reducers, crushers, papermaking machinery, and conveying equipment. Thanks to their efficient and reliable performance, they have become the ideal choice in the industrial sector for applications involving high loads and continuous operation.
