Double Row Spherical Roller Bearings Feature Two Rows Of Barrel Shaped Rollers 2

Benefits & Advantages of BKZ Industry Double Row Spherical Roller Bearings

BKZ Industry double row self-aligning spherical roller bearings are engineered for demanding applications involving heavy loads, shock loads, and vibration. With over 15 years of manufacturing and export experience, BKZ delivers reliable performance, consistent quality, and dependable supply for global OEM and industrial customers.

Key Features of Double Row Spherical Roller Bearings

High Load Capacity

Featuring two rows of barrel-shaped rollers, these bearings provide a larger contact area with line contact and optimized load distribution. The advanced roller geometry enables them to carry heavy radial loads while supporting axial loads in both directions.

Lower Vibration and Noise

The spherical outer ring raceway allows automatic alignment, while logarithmic roller profiles reduce edge stress and ensure more even load distribution. This design effectively minimizes vibration and ensures low noise operation under load.

Allows Shaft Misalignment

The outer ring features a spherical raceway whose center coincides with the bearing center. This design enables the bearing to automatically accommodate angular misalignment between the shaft and housing.

Long Service Life

Optimized internal geometry and uniform load distribution, combined with high-quality bearing steel (e.g., GCr15 / 100Cr6), reduce stress concentration and wear, resulting in extended service life.

Reduced Maintenance Frequency

Self-aligning capability and reduced internal stress help extend lubrication life, while optional sealed designs prevent contamination, reducing relubrication needs and enabling more reliable, continuous operation.

Types of Double Row Spherical Roller Bearings

Double row spherical roller bearings are primarily classified by dimension series, including 213, 222, 223, 230, 231, 232, 239, 241, 248, and 249 series. In addition, they can be configured with different sealing types (open or sealed), bore types (cylindrical or tapered), and cage materials (steel or brass) to meet various application requirements. Here are some of these types.

213 Series Double Row Spherical Roller Bearings

213 Series Double-row Spherical Roller Bearings

With a bore range of 20–140 mm, the 213 series is designed with a compact cross-section and reduced width, making it ideal for installations where space is limited. Its two-row roller structure supports moderate loads, and it is commonly supplied with steel or brass cages in open or sealed configurations for gearboxes and pumps.

What is the Application of Double Row Spherical Roller Bearing?

With a broad range of bore sizes, double row spherical roller bearings are widely applied in heavy industries such as mining, steel, cement, and wind energy. Their high load carrying capacity and self-aligning capability make them ideal for applications subject to shaft deflection and misalignment.

FAQs About Double Row Spherical Roller Bearing

Q1. What Is The Difference Between Single Row And Double Row Spherical Roller Bearings?

The main difference is structure and load capacity. Double Row Spherical Roller Bearings have two rows of rollers, so they can carry much heavier radial loads and also axial loads in both directions. They also allow misalignment. In practice, spherical roller bearings are almost always double row, since single row types are rarely used.

Common cage types include steel and brass. CC is a pressed steel cage with a floating guide ring, suitable for general use. CA is a machined brass cage with inner ring flanges for heavier loads. MB and MA are brass cages guided by inner or outer ring. Different cage designs affect speed, strength, and application conditions.

“K” means the bearing has a tapered bore with a 1:12 taper. This allows the bearing to be mounted using adapter or withdrawal sleeves, making installation and removal easier, especially for larger shafts.

“K” indicates a 1:12 taper, which is standard. “K30” means a 1:30 taper, usually used in larger bearings like 240 and 241 series. The 1:30 taper provides more precise positioning and is better suited for heavy-duty and large-size applications.

Double Row Spherical Roller Bearings can accommodate misalignment and carry both radial and axial loads. Double Row Cylindrical Roller Bearings mainly carry high radial loads with high rigidity but cannot handle misalignment well and have limited axial load capacity.
