Roller Thrust Bearing Highest Load Density Ensures Functioning


We all know that basic function of bearing is to support the load and to reduce friction caused during the motion when a machine parts move. It’s very key and critical component of a machine and can never be compromised. There are broadly two main categories of bearings Plain or Slider type bearing and Rolling or Anti Friction bearing. we will mention about bearing used for heavy loads.

Suited for Heavy Type Load With Best Performance

Roller Thrust Bearing

The roller thrust bearings available make in the market is cylindrical as well as spherical rollers type. The feature of thrust roller bearing is to withstand only axial type of load, however it is also ideal for heavy load. And that why this type of bearing possesses high axial range of rigidity. Thrust roller bearings are manufactured in various shapes Cylindrical, Spherical, needle roller thrust etc. Right from automotive to aerospace industry thrust roller type bearing is widely used. There are many international and national reputed manufacturers offering huge range of bearings with special features.

Spherical thrust type roller bearing has convex roller with a self- aligning feature. It is free from any effect of shaft deflection or mounting error. While in application, this bearing allows maximum misalignment of approx. Two degrees in shaft. Also contact angle input supports this bearing type to hold small quantum of radial type of load.  While doing lubrication in these bearing one has to be careful as large sliding of contact area can cause smearing. And to avoid this, utmost care must be taken in maintaining to the least specified minimum load.

Caters to many industries

Spherical Roller Thrust bearing have feature for permitting angular misalignment and also rotation with very low friction. The design of this bearing enables to take heavy axial load in singular direction and can also take radial load. This type of bearing is used in various industrial application involving heavy axial load, moderate level of speed as well as probable misalignments. A few of common applications are:

  • Gearboxes
  • Pulp and paper processing unit equipment
  • Offshore Drilling
  • Marine propulsion
  • Crane
  • Swing Bridge
  • Water turbines
  • Extruder for injection mouldings

The selection of material for this bearing can vary from one manufacturer to others. But most common materials are chrome steel and for the bearing cage is Sheet Steel, Steel and brass etc.

Understanding of bearing types, specification and usage will ensure expected level of performance. the machine can function with the best and suitable components fitted inside, so always ensure quality product. The internal design of bearing can vary from one manufacturer to another one so a thorough glance at the product will reduce hassles at a later stage.
