Aircraft Bearing Swaging Tools - Toll Free: 877-477-7823 Customer Service: 800-861-3192 Fax: 800-329-3020 Heating of the bearing inner race utilizing an induction heater may uphold installation efforts. However, in some installations, a heated bearing could be moved onto a shaft with your hands.
Bear in mind: Because a bearing must not be warmed above; the lubrication cap, cage cap, seal limitation, or potentially any associated material restrictions. So an arbor press is encouraged if an induction heater is not handy.

A suitable layout and installation approach is required for a long super precision bearing life. A couple of main facets are: effective pre-load technique, bearing dimension, load capacities, duty cycles, etc. Click here for examples of bearing arrangements.

Centrifugal forces are an issue for inner race take off at elevated RPM's. Consequently, correction factors have to be created for each RPM and thermal effects on materials. Principles of a slight push on the internal race and slight opening on the outer race can frequently be made.
Be cautious of being overly general, doing this can open up a single up for an easily prevented problem. Please click here for more information on tolerances and thermal effects on mating parts. Please click here for more information on tolerances and thermal effects on mating parts.
The primary source of unanticipated precision bearing failure is contaminants. To duplicate, the first source of early super precision bearing failure is contamination. The tidier your space can be, the better your possibility for an expanded bearing life.
System Layout And Pre-Load
A different area where there is no machining, no grinding, and no other fragments being created is really suggested. A well-maintained work station is needed at the bare minimum. Moreover, it is strongly advised not to open the enclosed bearing delivery bag prior to immediately before installment.
Take note that in fact, a human hair is contamination for a super precision ball bearing. Just an individual human hair may simply cut down bearing life. Several facilities will utilize clean room apparel such as gloves, aprons, hair nets, etc.
to keep bearing corruption. This must be taken into consideration through super precision bearing installation. An Arbor press is encouraged considering that the press may be done in a single motion. Stopping and initiating a press with the shaft may enhance possibilities for errors.
Despite it is highly urged against, if one has to work with a hammer make certain that it is a dead blow hammer. In no way use the dead blow hammer straight against the bearing, a mid-level tool is required (much like press tools mentioned above).
Equipment Strength
A ball peen or metal hammer will greatly increase the possibility for precision bearing accidents. A complete and well thought-out break in procedure might be the difference between a short and long precision bearing lifespan. Regardless of what the lubing medium is, polishing results happen during breaks in that enhance the precision bearing functionality.
Thus, a proper initial and break in process should not be sold short even for oil greased bearings. 'Grease Fling' can cause an extremely brief grease lubrication lifespan, all the same as administering a spindle ahead of the oil jets turn on can considerably lower bearing life.
Please click here for a proper break in procedure example and further information. Bearing swaging is just as necessary as bearing design and cleanliness. Incorrect replacement could wreck the bearing assembly. During installation, at no time can any installation forces be transmitted off 1 bearing ring into the other with the balls.
Faulty installation can easily trigger burning of the bearing, which may result in bearing vibration, sounds, plus decreased lifespan. See our Bearing Managing Method page for additional information regarding effective installation of the bearing within your part.
Bearing Arbor Press
American Precision specializes in various methods of bearing swaging, retention and proof load testing. Retention methods include bearing swaging, roller swaging, anvil swaging, bearing staking, anvil staking, and chisel staking. Processes are performed to a wide variety of Aerospace, Military and Commercial specifications.
Contact us for your next project. Bearing staking tools are required to ensure that the bearing races are not dimly throughout installation utilizing improper bearing reinforcement. In the event that a bearing is pushed on to a shaft or within a housing passing the installation press fit load through the bearing, plastic deformation – concavity – can happen and substantially diminish the bearing life and performance aspects.
As noticed in the example photograph, installation tools could press on a single race or both of the bearing races. Every setup could change. In case there is any uncertainty contact GMN USA engineering support for recommendations.
