Floating bearings, also known as self-aligning bearings, are a type of bearing that allows for self-alignment of the shaft within the bearing housing. This makes them ideal for applications where shaft alignment is difficult or impossible to maintain, such as in misaligned shafts, thermal expansion, or dynamic loads.
There are several types of floating bearings, each with its own unique design and characteristics:
Type | Design | Pros | Cons |
---|---|---|---|
Spherical Roller Bearings | Spherical rollers in a two-piece housing | High load capacity, self-alignment, shock resistance | Limited axial load capacity |
Torsionally Rigid Bearings | Inner and outer rings connected by a flexible element | High torsional stiffness, allows for shaft misalignment | Limited axial load capacity |
Trunnion Mounted Bearings | Bearing mounted on a trunnion or pivot | High load capacity, self-alignment, ease of installation | Limited angular misalignment |
Swivel Bearings | Bearing housing can rotate around the shaft | High angular misalignment, compact design | Limited load capacity |
Floating bearings are widely used in a variety of industries and applications, including:
Floating bearings play a critical role in ensuring the smooth operation and longevity of equipment in various industries. By accommodating shaft misalignment and thermal expansion, floating bearings prevent premature bearing failure, reduce maintenance costs, and improve overall system performance.
Selecting the right floating bearing for an application requires careful consideration of several factors:
Proper maintenance is essential to extend the life and performance of floating bearings. Regular maintenance includes:
