1.Angular Contact Ball Bearing Description:
Angular contact ball bearing can withstand radial load and axial
load simultaneously, as well as the pure axle loads. They have
higher limit speed. High precision and high speed bearings usually
take 15 degrees contact Angle. The contact angle decide the
capacity of axial load. Retainers are made of brass, synthetic
resins or others subject to individual bearing features and
application conditions.
Single-row angular contact ball bearings can accommodate axial load
in one direction, if enduring radial load, it will raise additional
axial force. And only limited axial displacement of the shaft or
housing in one direction. The contact angle of angular contact ball
bearings is 40, so you can afford a large axial load. Design of
angular contact ball bearing is non-separable, shoulder height on
both sides of the inners and outer rings are different. In order to
increase the bearing load capacity, lower one side of the shoulder,
so that the bearing can be mounted into more balls.
2.Angular Contact Ball Bearing Application :
Machine tool spindle,
High frequency motor,
Gas turbine,
Centrifuge,
Oil pump,
Roots blower,
Air compressor,
Transmission,
Printing machinery.
3.SIMON Bearing of Shields,Seals :
Bearings with two enclosures are pre-greased at the factory and are
classified as “greased for life”. This simply means that the type
and amount of grease is sufficient to outlast most general
applications, with the exception of temperature extremes,
contamination, high load and high speed.
Enclosures are defined as either contact or non-contact and refer
to any gap at the inner ring. The popular Z metallic shield does a
good job of keeping the grease in place and larger contaminants out
of the bearings. SIMON applies an anti-corrosive coating to their Z
shield in the event of moisture and because they are non-contact,
their operating speed and starting torque are unaffected.
For more arduous service conditions, the seal is in full contact
with the inner ring, increasing grease retention and excluding a
wider range of contaminants from entering the bearing but generate
more head and therefore have reduced operating speeds. Enter the V
seal from SIMON. Zero drag, low staring torque, maximum operating
speeds, no excessive heat and increased grease retention and
contaminant protection over the shield design. The V seal from
SAIFAN delivers an alternative that’s fast becoming the standard in
all bearings.
4.Angular Contact Ball Bearing Features
1) Load capacities are higher than deep groove ball bearings of
same dimensions
2) Used for bearing radial-axial combined loads or pure thrust
loads
3) Low operating friction and high limiting speed
