Spherical roller thrust bearings

Spherical roller thrust bearings – extreme load capacity and self-alignment

Spherical roller thrust bearings are the most structurally advanced components among thrust bearings. They are characterized by the highest load-carrying capacity, enabling the design of compact systems with exceptionally high power density. Due to the inclination of the raceways relative to the bearing axis, these bearings successfully accommodate not only massive axial forces but also significant radial loads (up to 55% of the axial load value). At e-marat.pl, we offer these components for the toughest engineering tasks.

A unique feature of spherical roller thrust bearings is their capability for angular misalignment. The spherical surface of the housing washer raceway makes the bearing insensitive to shaft deflections and misalignment relative to the housing (up to 2-3 degrees). This allows for stable operation under conditions where other thrust bearings would suffer premature wear.

Design, mounting, and cage variants

These bearings feature a separable design—the housing washer can be mounted independently of the shaft washer assembly with the cage and rollers. Depending on the application requirements, various design solutions are utilized:

• Massive machined brass or steel cages – guided on a steel sleeve, ideal for operation at high rotational speeds and under heavy overloads.
• Pressed steel cages – a solution requiring the use of a hardened spacer sleeve between the shaft washer and the shaft shoulder.
• Paired arrangements – mounting in an O or X arrangement enables the accommodation of axial loads in both directions.

Why choose spherical roller thrust bearings from our product range?

• They guarantee low friction and long service life even under heavy shock loads.
• They enable the creation of highly rigid or self-aligning bearing arrangements.
• They ensure safe operation at high rotational speeds.
