Single Row Spherical Roller Bearings

Single row spherical roller bearings are made up of an outer ring with a spherical surface as the raceway, and an inner ring with raceways matched to the spherical rollers, with a single row of spherical rollers, a cage, and optional seals, shields, or lubrication. With this special design, they can allow self-alignment when shaft misalignment occurs. They are used for high radial load capacity and moderate axial load capacity, and can handle shock and vibration loads.
BKZ Industry, with ISO 9001 certification and 15 years of bearing manufacturing experience, offers single row spherical roller bearings made from high quality materials such as high carbon chromium bearing steel (GCr15 / 52100), with steel cage / brass cage / polyamide cage options, ensuring the bearings can offer long service life, reduce friction, and ensure the shaft works stably. It offers standard types, with adapter sleeve, with withdrawal sleeve, open or sealed types, cylindrical bore or tapered bore based on different applications.

Single Row Spherical Roller Bearings With One Single Row Of Spherical Rollers

Benefits and Advantages of BKZ Industry Single Row Spherical Roller Bearings

Single row spherical roller bearings manufactured by BKZ Industry are designed for self-alignment, higher radial and axial load capacity than ball bearings, longer service life, and shock and vibration load capacity. BKZ Industry offers different options produced in its two factories and exports worldwide.

Benefts of Single Row Spherical Roller Bearings

Self-aligning Capability

Its spherical outer ring raceway and single row barrel-shaped rollers allow alignment adjustment as the spherical rollers shift position and the inner ring tilts relative to the outer ring.

High Radial Load and Moderate Axial Load Capacity

Compared with ball bearings, spherical rollers are longer and thicker, creating line contact rather than point contact. This design allows the bearing to support high radial loads, and the contact angle enables it to carry moderate axial loads as well.

Long Service Life under Heavy Load Conditions

With the larger contact area and lower contact stress, reducing the influence of shaft deflection, installation misalignment, etc., and with proper sealing and lubrication, and protection from contamination, they can achieve long service life under heavy load conditions.

Shock and Vibration Load Capacity

Different from ball bearings, these bearings have barrel-shaped rollers which provide line contact, making the bearing work more stably and reducing the impact of shock and vibration.

Various Options for Different Applications

With cylindrical bore or tapered bore, adapter sleeve or withdrawal sleeve, and open or sealed options, they are available for different applications and working environments.

Single Row Spherical Roller Bearing Applications

Single row spherical roller bearings are designed with self-aligning capability and high radial load capacity, making them suitable for heavy-duty equipment operating under shock loads, vibration, and misalignment conditions. They are widely used in heavy industries and power transmission equipment.

FAQs About Single Row Spherical Roller Bearings

Q1. What is the Difference between Single Row and Double Row Spherical Roller Bearings?

Single row spherical roller bearings have one row of barrel-shaped rollers and a spherical outer raceway, while double row spherical roller bearings have two rows of rollers, allowing higher load capacity. Double row types can carry heavy radial loads and axial loads in both directions, whereas single row bearings mainly carry radial loads with limited axial load capacity in one direction.

Single row spherical roller bearings are typically made from high carbon chromium bearing steel such as GCr15 or SAE 52100. For special applications, stainless steel, carburized alloy steel, or heat-resistant steel may be used. Cages are usually made from steel, brass, or reinforced polyamide depending on operating speed, load, and temperature conditions.

Single row spherical roller bearings can typically accommodate misalignment of about 1° to 3°, depending on the bearing design, internal clearance, and operating conditions. Their spherical outer raceway allows the rollers to adjust automatically, making them suitable for applications where shaft deflection, installation errors, or housing deformation may occur.

To order a single row spherical roller bearing, you can provide the bearing number directly. If the bearing number is unknown, important information includes shaft diameter, housing dimensions, load type, speed, operating temperature, lubrication method, and application details. This information helps engineers select the correct bearing type and clearance.

Yes, bearings can be branded with customer logos through OEM or private label services. Manufacturers can laser mark or engrave customer logos on the bearing rings and customize packaging, labels, and cartons. OEM branding usually requires minimum order quantities and confirmation of drawings or marking details before production.

BKZ Industry Bearing factories use roundness testers, roughness testers, hardness testers, coordinate measuring machines (CMM), internal clearance measuring instruments, vibration and noise testers, metallographic microscopes, and load testing machines. These inspection tools ensure bearing accuracy, surface finish, hardness, internal clearance, and overall bearing performance meet quality standards.
