Single / Double Direction Thrust Angular Contact Ball Bearings With Outer Cover
RKF thrust ball bearing is separable including a shaft washer (fit
with journal) a housing washer (fit with bearing block) a group of
steel balls and a cage which make it very convenient to fit with
journal and bearing block respectively.
RKF thrust ball bearings due to different structures can be divided
into single direction thrust ball bearings double directions thrust
ball bearings and angular contact thrust ball bearings.
Single Direction Thrust Ball Bearings
Single direction thrust ball bearings can only be used to carry
axial load in one direction but radial load. It can make an axial
location in one direction.
Single direction thrust ball bearings have planar housing washer
and aligning seat washer. Generally planar housing washer can not
allow any angular error; however when designing bracing structures
a gap of 0.5-1mm between the outer diameter of housing washer and
the fitting surface of bearing block can be kept out to correct the
angular errors which would be made when mounting. Attention please
aligning housing washer need to be ordered additionally.
Double-Direction Thrust Ball Bearings
Double-direction thrust ball bearing can carry axial loads in
double directions but it can not carry radial load.
Double-direction thrust ball bearings can make axial location in
two directions.
Double-direction thrust ball bearings also have planar housing
washer and self-aligning seat washer. Generally planar housing
washer can not allow any angular error; however when designing
bracing structures a gap of 0.5-1mm between the outer diameter of
housing washer and the fitting surface of bearing block can be kept
out to correct the angular errors which would be made when
mounting. Self-aligning housing washer need to be ordered and
manufactured additionally.
Angular Contact Thrust Ball Bearings
Angular contact thrust ball bearing mainly carry axial load and it
also can carry certain radial load. Compared with thrust ball
bearings of the same dimension the allowable limiting speed is
higher. It can make an axial location in one direction.
Angular contact thrust ball bearings can make up the weakness of
thrust ball bearings with flat back face which can not carry radial
loads. The contact angles are 45oand 60o. The smaller the degree of
contact angle the higher the capacity of radial load is.
Thrust Ball Bearing with Outer Cover
The structure of thrust ball bearing with outer cover is the same
with that of single direction thrust ball bearing but there is an
outer cover on seat washer (or there are out covers on inner and
outer diameters of a seat washer). The structure is as Fig 1 and
Fig 2. Thrust ball bearing with an outer cover is non-separable
because of the outer cover. The outer cover is used for dustproof.
The structure of Fig 2 can help fill lubricants.
Thrust ball bearing with outer covers can carry axial loads in one
direction but it can not carry radial loads. It also can make an
axial location in one direction.
RKF also can provide thrust ball bearings with other special
structures such as thrust ball bearings without cages
unidirectional thrust ball bearings with taper bores unidirectional
thrust ball bearings with steel wire raceway and etc. Please
forgive us cant list all the product types here. If customer has
special requirements RKF technical department is ready for your
consultation.
Cages
Cages of thrust ball bearings supplied by RKF are pressed steel
cages machined solid cages made of brass or bronze special fabric
reinforced phenolic resin cages and etc. Cages of different
material are identified by suffix. Further details will be found in
RKF catalogue "bearing material".
