Rolling bearings support and guide rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.

Spherical Roller Thrust Bearings

Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. These versatile bearings can contain single or multiple rows of rolling elements; multiple rows can significantly improve radial load capacity. Also, the use of different roller shapes can further reduce friction and support both radial and axial loads.

Roller bearings are used in rotary applications to replace sliding movement with low friction, rolling. Automated roller bearing setting techniques offer many advantages like reduced setting time, assembly cost, and reliable setting. To select the right roller bearing, one must determine the desired bearing life and a sufficient basic dynamic load rating to meet that life requirement. Roller bearings are used in power generation, wind turbines, gear drives, rolling mills, machine tool spindles, gear reduction units, etc.

The spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction and permits angular misalignment. The bearing is designed to take radial and heavy axial loads in one direction. Spherical thrust roller bearings contain convex rollers and have a self-aligning capability, and are free of any influence of mounting error or shaft deflection. Standard cages are machined brass, where the E-type offers a pressed cage for high load capacity. These are thrust bearings containing convex rollers. They have a self-aligning capability and are free of any influence of mounting error or shaft deflection. Besides the original type, the E type with pressed cages for high load capacity is also available. Their bearing numbers are suffixed by E. For horizontal shafts or high-speed applications, machined brass cages are recommended. Spherical thrust roller bearings carry pure thrust or axial loads with little or no radial forces. They use barrel-shaped rolling elements to carry single- or double-direction thrust loads. These rollers have a length perpendicular to the shaft and have different shapes that affect the bearing’s efficiency. The two rings on roller thrust bearings, called washers, are configured with different shapes and designs.

Spherical Roller Thrust Bearing Mounting:

Spherical Roller Thrust Bearing Mounting: spherical roller thrust bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly.

Applications of Spherical thrust roller bearings:

Spherical thrust roller bearings achieve a high thrust capacity with low friction and continuous roller alignment. This bearing type is ideal for operating conditions that experience heavy loads, difficulty in establishing or maintaining housing alignment, or shaft deflection. Spherical thrust roller bearings are widely used in the steel industry, mining & construction, paper-making machinery, wind turbines, machine tools, gearboxes, electric motors, pumps & compressors, and injection molding machines.

Features of Spherical thrust roller bearings:

  • High load-carrying capacity
    The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.
  • Accommodate misalignment
    SKF spherical roller thrust bearings are self-aligning and can accommodate misalignment.
  • Separable design
    SKF spherical roller thrust bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition, this facilitates maintenance inspections.
  • High-speed capability
    The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.
  • Long service life
    The particular roller profile reduces edge stresses at the roller/raceway contact.
  • Low friction
    The optimized roller end/flange contact keeps frictional heat low, even at high speeds.
