Audited Supplier LYHY is a professional manufacturer in self-aligning roller bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer's different technical requirements.
Self-aligning roller bearings is also called spherical roller bearings, they have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearings axis. The centre point of the sphere in the outer ring raceway is at the bearings axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Self-aligning roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
LYHY self-aligning roller bearings' structure:
Four common structures of spherical roller bearings can be described in the following:
CC series self-aligning roller bearings has two window-type steel cages, flangeless inner ring and guide ring centered on the inner ring.
CA series self-aligning roller bearings has one-piece machined brass cage, double-pronged, retaining flanges on the inner ring and guide ring centered on the inner ring.
MB series self-aligning roller bearings has two-piece machined brass cage, double-pronged, retaining flanges on the inner ring and guide ring centered on the inner ring.
In addition, with some exceptions, all LYHY self-aligning roller bearings are manufactured with a cylindrical bore as well as with a tapered bore. Below are some suffixes for your reference.
Suffix K30: a taper of 1:30, in the 240, 241, 248 and 249 series
Suffix K: a taper of 1:12, in the other series
Suffix W33: an annular groove and three lubrication holes in the outer ring
Suffix W20: three lubrication holes in the outer ring
The special profile distributes loads more evenly along the rollers and prevents stress peaks at the roller ends to extend bearings service life.
2. Self-guiding rollers reduce friction and frictional heat.
3. A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
Application
LYHY self-aligning roller bearings can be applied in the following field:
Paper mills
Printing presses,
Railway vehicles
Continuous casters
Coaters in high precision execution
High temperature applications
