Barrel Roller Bearings
Barrel Roller Bearings belong to the group of spherical bearings and are single row, self-retaining radial roller bearings. Their unique feature makes them particularly suitable for applications where exact shaft alignment is not always possible or required.
The outer ring has a hollow spherical raceway that provides positioning flexibility for the inner ring and compensates for small angular errors between the two rings. This improves performance and service life, which is useful in situations involving thermal expansion or other dynamic effects.
The inner ring is equipped with a specially shaped raceway that allows the barrel-shaped rollers to run safely and accurately. Barrel bearings are robust and can withstand high radial loads.
Typical applications for spherical roller bearings include rolling mills, extruders, vibratory machinery, paper machines, generators and wind turbines. In these applications, high loads, vibrations and impact forces often occur, which the spherical roller bearings can withstand. Their ability to accommodate angular misalignment while providing reliable bearing support makes them a preferred choice in such industrial environments.
Depending on the specific requirements and bore diameter, several variations of barrel bearings are available such as single row or double row bearings, with or without a cage. They can be equipped with a cylindrical or conical bore to meet individual needs. This ensures an optimal fit and functionality in various applications.
