High speed nsk thrust bearing 51118 axial bearing 51118
Discription of high speed nsk thrust bearing 51118 axial bearing
Axial bearing 51118 are produced as single direction or double
direction thrust ball bearings. They are designed to accommodate
axial loads only and must not be subjected to any radial load.
Thrust ball bearings are separable, the shaft washer, housing
washer(s), ball and cage assembly(s) can be mounted separately.
Shaft washers have a ground bore to enable an interference fit. The
bore of the housing washer is turned and always larger than the
shaft washer bore.
Two Types of axial bearing:
A: Single direction thrust ball bearings: consist of two washers
with raceways and balls guided b a cage. Washers have flat seating
surfaces, and that is why they must be supported so that all balls
can be evenly loaded. Bearings carry the axial load only in one
direction. They are not able to carry radial forces.
B: Double direction thrust ball bearings: have two cages with balls
between the central shaft washer and two houding washers with flat
seating surfaces. The shaft washer has raceways on both sides and
is fixed on the journal. Bearings are able to carry only axial
forces in both directions.
Specifications for axial bearing:
1. Thrust ball bearing Equipped with one-way, two-way two types
2. In order to allow installation error, either one-way or two-way,
can choose spherical self-aligning spherical seat cushion type or
with spherical seat type.
3. High quality steel - used can extend bearing life highest 80%
super clean steel
4. The height of the grease technology - lubricants technology can
make the life of the grease to extend and improve the performance
of the bearing
5. The high grade ball - quiet and smooth when high-speed rotation
6. Use of options in the ring, can allow installation error.
Application of thrust ball bearing:
1.Thrust Ball Bearings should use close to the radial bearing, in
order to prevent the effect of shafts deflection.
2.When using big size ball bearings on a horizontal shaft, preload
should be implemented to prevent the clearance between housing
washer and balls.
3.Under the inevitable circumstances of shaft deflection and
misalignment, aligning seat washer should be applied.
