Spherical Roller Bearings

Spherical roller bearings consist of barrel-shaped rollers, an outer ring with a spherical raceway, and an inner ring with one or two raceways depending on whether the bearing is single row or double row. They also include a cage (steel, brass, or polyamide), optional guide rings, and seals for sealed versions. These bearings are self-aligning rolling bearings that can compensate for shaft misalignment and housing deformation. They are designed to carry very high radial loads and axial loads in both directions for double row designs, while single row designs mainly carry radial loads with limited axial load capacity in one direction. They are suitable for shock loads, vibration, and heavy-duty operating conditions.

BKZ Industry is a spherical roller bearing manufacturer with 15 years of bearing manufacturing experience and two factories.

Spherical Roller Bearings For Misalignment

Features & Benefits of Spherical Roller Bearings

Spherical roller bearings are designed to handle heavy radial and axial loads while accommodating shaft misalignment. Their robust internal design makes them suitable for shock loads, vibration, and harsh operating environments. With long service life, reliable performance, and multiple design options available, they are widely used in heavy-duty industrial equipment and demanding applications.

Key Features of Spherical Roller Bearings

Self-aligning Design

With barrel-shaped rollers and a spherical raceway in the outer ring, spherical roller bearings can automatically adjust to shaft misalignment caused by shaft deflection, mounting errors, or housing deformation. This self-aligning capability reduces edge stress on the rollers and raceways, improving bearing reliability and service life.

Very High Radial Load Carrying Capacity

Spherical roller bearings use barrel-shaped rollers that create line contact with the raceways, providing a much larger contact area than ball bearings. This design allows the bearings to support very high radial loads and makes them suitable for heavy-duty equipment such as crushers, gearboxes, vibrating screens, and rolling mills.

Axial Load Capacity

Double row spherical roller bearings can carry axial loads in both directions in addition to heavy radial loads. Single row spherical roller bearings mainly carry radial loads and can support limited axial loads, typically in one direction, depending on the internal design and guide ring configuration.

Suitable for shock loads and vibration

The large roller contact area, heavy-duty internal design, and self-aligning capability allow spherical roller bearings to perform reliably under shock loads, vibration, and misalignment conditions. They are widely used in mining, construction, steel mills, and vibrating equipment.

Various Design Options

Spherical roller bearings are available in many designs including open and sealed types, steel cage, brass cage, and polyamide cage designs, solid lubricant bearings, split spherical roller bearings, and both single row and double row configurations to meet different operating conditions and installation requirements.

Benefits of Spherical Roller Bearings

Reduce Maintenance Cost

Sealed spherical roller bearings and solid lubricant bearings can operate with little or no relubrication, reducing maintenance frequency and lubrication costs. Their self-aligning capability also reduces damage caused by misalignment, further lowering maintenance costs.

Longer Service Life

Due to line contact between rollers and raceways, optimized internal geometry, and high-quality bearing materials, spherical roller bearings can achieve long service life even under heavy loads and harsh operating conditions.

Reduce Downtime

Split spherical roller bearings and adapter or withdrawal sleeve designs allow easier installation and removal without disassembling surrounding equipment, significantly reducing machine downtime during maintenance and replacement.

Reliable Performance in Harsh Operating Conditions

With heavy-duty internal design, high load capacity, sealing options, and corrosion-resistant materials, spherical roller bearings can operate reliably in dusty, wet, high-temperature, and heavy-load environments.

Easy installation and replacement options

Spherical roller bearings are available with adapter sleeves, withdrawal sleeves, and split bearing designs, making installation and removal easier, especially for large bearings and heavy equipment.

Applications of Spherical Roller Bearings

Spherical roller bearings are available in various sizes and designs, making them suitable for a wide range of industrial applications, especially where heavy loads, shock loads, and misalignment are present.

FAQs About Spherical Roller Bearings

Q1. Tapered Roller Bearing vs Spherical Roller Bearing: What Are Their Differences?

The biggest difference is load direction and alignment capability. Tapered roller bearings are designed for combined radial and axial loads with precise shaft positioning, while spherical roller bearings are built for heavy radial loads, shock loads, and misalignment conditions. In simple terms, tapered roller bearings are for precision and positioning, while spherical roller bearings are for heavy loads and harsh environments.

The key difference is misalignment capability and load type. Cylindrical roller bearings mainly carry very high radial loads and operate at higher speeds, but they cannot handle misalignment. Spherical roller bearings can carry heavy radial and axial loads and allow shaft misalignment and shaft deflection. So cylindrical is for high speed and rigidity, spherical is for heavy load and misalignment.

A spherical roller bearing with an adapter sleeve is designed for mounting the bearing onto a plain shaft without shoulders. The adapter sleeve allows easy installation, positioning, and removal without machining the shaft. This design is very common in conveyors, fans, and agricultural equipment where easy installation and maintenance are important.

A withdrawal sleeve is used to mount and remove spherical roller bearings on stepped shafts. The sleeve makes bearing removal much easier, especially for large bearings and heavy equipment. This design is commonly used in mining, steel mills, crushers, and gearboxes where bearings need frequent maintenance or replacement.

The most important information is the bearing number. If the bearing number is not available, then provide bore diameter, outside diameter, width, drawings, shaft size, housing size, load conditions, speed, and application. With this information, engineers can select the correct bearing, clearance, cage type, and lubrication method.

Yes, spherical roller bearings can be customized for different working conditions. Common custom options include special clearance, special cage materials, seals, lubrication holes, coatings, heat treatment, and special materials for high temperature or corrosion environments. Custom bearings are widely used in mining, cement, steel, and heavy industry equipment.
