Spherical Roller Bearings

Double row spherical roller bearings are suitable for larger radial loads. They can be used at moderate speeds with some axial load in either direction. Double row spherical bearing has spherical raceways on the outer rings of both rows of rollers, which can be self-aligned over a wide range and can accept small misalignments.

Double row spherical roller bearing material

These double row self aligning spherical roller bearings are available in a variety of materials depending on the application and operating environment. Chromium steel is one of the most commonly used materials in the production of these bearings due to its durability, but steel plate, polyamide and brass are also used in some applications. One of the most important parts of a spherical bearing is the cage that holds the bearing in place. The cage is usually made of pressed steel or brass, as both materials are strong and temperature resistant.

These double spherical roller bearings have seals to protect against contaminants such as dirt, liquids, debris, and harsh temperatures.

Two different types of double row spherical roller bearing

Single row spherical roller bearings
Widely used where only low radial load capacity is required. Apart from the difference in load capacity, single row spherical roller bearings are very similar to their counterparts in terms of performance and durability.

Double row spherical roller bearings
Used where high radial load capacity is an essential part of almost all heavy machinery. Double row roller bearings feature a central flange to optimize the overall performance of the equipment.

Double row spherical roller bearing application

Spherical bearings are an important part of heavy machinery such as gearboxes, turbines, mechanical fans, construction equipment, mining equipment and drilling equipment. Roller bearings are available in a variety of standard sizes and dimensions, but custom sizes and specifications are also available.

What is the main difference between single row and double row bearings?
Single row ball bearings have a row of balls and are suitable for applications with relatively low radial and axial loads. Double row ball bearings have two rows for applications where higher loads are expected or higher reliability is required

Why use double row roller bearings?
Double-row or two-row cylindrical roller bearings are designed for heavy loads that single-row bearings cannot handle. An extra row of rollers allows for increased radial loads.
