|FR156-2RS Full Ceramic Ball Bearing
3/16" x 5/16" x1/8" inch
FR156-2RS Full Ceramic Flanged Ball Bearing, the inner diameter is 3/16", outer diameter is5/16" and the width is 1/8", this is a popular size that could be used in many applications, Bearing is made of Ceramic.
Full zirconia ceramic high temperature bearings, generally used to make Teflon holder, according to customer requirements, there will be protection of steel, PEEK, etc. retainer, high temperature up to 260 degrees or slightly higher, with a self-lubricating oil, high-speed operation, corrosion resistance, and other characteristics, and appearance!Zirconia has full ball bearings, although the speed is relatively lower, but can be high temperature of 500 degrees. Choose corrosion-resistant bearings, acid bearings, high temperature bearings, oil-free self-lubricating bearings, high-speed bearings, ceramic bearings is undoubtedly the best choice.
Ceramic Bearing Installation and Precautions
1. Ceramic bearing installation
When installing ceramic bearings,Works on the need the circumference of the ferrule end face exert equal pressure.smoothly into the ferrule,Prohibited with a hammer and other heavy objects
direct percussion bearing face so as not to damage the bearings!Strictly prohibit
exert pressure on one aspect of the ferrule (For example, the outer ring),Through rolling
pressed into the other rings(for example inner circle)So as not to cause the raceway indentations or abrasions, affecting the normal use of the bearing.
Wan not be used, in particular, will be installed at Non-separable bearings on shaft and bearing housing,Should be used pads iron simultaneously pressed into the Inner and outer rings!As shown below.
The ceramic bearings onto the shaft as shown below.
The ceramic bearings mounted to the bearing housing as shown below.
The ceramic bearings reverse direction simultaneously into shaft and housing as shown below
This installation conditions will have some impact on the bearing,So they requested according
to the actual inner and outer diameter tolerances,priority principle by a tight fit,
first bearing into the shaft or bearing, Rest of the match recommended excessive fit and clearance fit.
2. Installation with ceramic bearings
(1):The amount of interference
The inner and outer roller bearing fixed to the shaft or the bearing housing,When it receives a load,
if the ring and the shaft or the bearing housing with the surface a radial, axial and rotational direction of
the relative movement,
mating surface will occur wear, friction or rubbing corrosion cracking, etc.,causing the bearing, shaft and
bearing box damage,
abrasion powder and then mixed into the interior of the bearing.This is leading to bearing dysfunctional,
abnormal heat or vibration the main reason.Fixed bearing on the way to the ring on the mating surfaces of the bearing housing
outflow amount of interference, for static tie for the best,The thin ring can be used with equal distribution
of the load on the
circumference, will not affect the load bearing capacity.
However, when mated using static in addition to outside not easy mounting and dismounting bearings,free side bearings with release bearing, you can not move axially,
Therefore, and can not be used for all occasions.Installation issues please contact the company specific.
(2) Selection of fit
With generally chosen according to the following principles.
According to the load acting on the bearing direction, nature and inner and outer rings of either rotation,
then the load on each ring can be divided into rotational load, static load, or non-directional load,Rotate the load and do not bear the load of the ring should be taken as directed interference fit (interference fit),
Ferrule to withstand static loads, it is desirable overly complex or dynamic fit (clearance fit)
Bearing load is large, or to withstand vibration, shock load, to increase the interference,
the hollow shaft, thin walled bearing housing or light alloy, plastic bearing housing, they should increase
the amount of interference.
Required to maintain a high rotational accuracy, it should be with high precision bearings,
shaft and the bearing housing and improve the dimensional accuracy and avoid excessive interference,
the shaft or the bearing housing may geometry Accuracy of geometry of the bearing ring, thereby
damaging the accuracy of rotation of the bearing.
If not separable bearings (such as deep groove ball bearings)static with inner and outer rings are used,
the bearing installation and removal is very inconvenient,
It is best to use inside and outside the ring moving with a party.
