What are the features of self aligning bearing housing?

Features of SNLself aligning bearing housing:
Modular system
The scope of supply of SNL self aligning bearing housing includes a series of bearing housings of different sizes but with the same design. They can be used together with a variety of standard seals and can be used under different working conditions and environments. SNL self aligning bearing housing is suitable for applications with shaft diameters between 20 and 160mm.

Enhanced base design
The SNL self aligning bearing housing adds some supporting parts and wall thickness around the connecting bolt hole to make the bottom of the SKF self aligning bearing housing stronger. Therefore, the connecting bolts can be locked tighter to improve the positioning ability, and the bearing seat can be prevented from deforming the seat hole due to excessive force.

Bearing seat connection
There are two connecting bolt holes on the base of the standard SNL self aligning bearing housing. SKF bearing housings with sizes 511-609 or above can be provided with four connecting bolt holes, code-named FSNL..NM. These larger housings can also be provided with a design without connecting bolt holes, code-named SSNLD, and users can process them according to the needs of the application. These SKF housings are made of ductile iron.
Smaller housings with sizes below 511-609 can also be installed with four bolts. There are some cast marks on the bearing housing to indicate where the holes can be drilled.

Good heat dissipation effect
Since the base of the SNL self aligning bearing housing adds some supporting parts, it also increases the surface area between the base and the supporting surface, so a larger amount of heat can be taken away from the bearing.

Device for relubrication
The standard SNL self aligning bearing housing has a grease nipple, which can facilitate maintenance personnel to replenish grease. There are also some cast marks on the bearing seat, which is convenient for users to add other grease nipple to supplement the lubrication of bearings or seals.

Identification marks on the top cover and base
The top cover and base of the bearing seat are processed together in manufacturing, so they must be used together. Different top covers and bases are absolutely not interchangeable. To prevent confusion, the top cover and base of each SNL self aligning bearing housing are marked with the same number for identification.

Mark to help install
There are some cast marks on the base of the SNL self aligning bearing housing to indicate the position of the axis of the seat hole. These marks can be used to facilitate installation and make the alignment more precise.

Mark holes for installing other parts
There are some special marks on the SNL self aligning bearing housing, which are used to indicate some positions that may need to be drilled; for example, positioning nails, sensors for condition monitoring, or adding other oil nozzles.
