Hydrodynamic Bearings
- 1. I have a bearing, but I can't identify it. What information does your company need?
If it is a Kingsbury bearing, please provide the numbers that are etched on the bearing, such as:
a) the drawing number (e.g., 365714, 470134, 27-10%-13A, 30-5-16AB), or
b) the previous order number (e.g., 57-195, 64-537, K991582), or
c) the identification number etched on the part (e.g., KI-IT 000166, KI-IT 027194, 366041-001).Please note that all major parts have been etched since 1980.
- 2. My bearing pad temperatures are running "hot". What should I do?
- Measured temperatures are mainly a function of the speed, load, clearance, oil supply temperature and oil flow rate for the application. Changes in any one of these parameters can have a corresponding effect on the measured pad temperature.
Most hot running bearings can be fixed by correcting the problem that caused one of the parameters shown above to change. If your application is running hot due to an overload condition, Kingsbury's
Sales Engineers can assist you in selecting a bearing that is suitable for the increased load.
Bearing temperatures should be measured just below the babbitt surface. Recommended locations for temperature sensors can be found in product catalogs LEG Thrust and Journal. - 3. I want to find out if my bearing can be repaired. How do I do this?
For repair of a fluid film bearing, contact our Repair and Field Service Division
For repair of a rolling element bearing, contact our Messinger Sales team.
Rolling Element Bearings
- 1. I have a bearing, but I can't identify it. What information does Messinger need?
If it is a Messinger Bearing, please provide a part # or serial # that is etched on the bearing. If it is not, please provide the following: bearing boundary dimensions, bearing type (thrust roller, radial roller, etc.), the original manufacturer of the equipment that it is used in, the OEM's drawing # or part #, the application that the bearing is in, and any other information that you may have pertaining to the bearing and its application.
- 2. If I order a custom bearing, what's the average turnaround time?
Messinger Bearings' core business is dedicated to providing custom bearings to the marketplace in a timely and reasonable manner, and we have been doing so for over 90 years. The bearing size, bearing type, and quantity, and current shop capacity, greatly impact the delivery schedule that would be proposed. With that in mind, the following generic estimated delivery by bearing size could be expected on a quantity of one piece:
Bearing I.D. up to 12" delivery of approximately 14 to 16 weeks
from 12" to 30" delivery of approximately 18 to 22 weeks
from 30" to 60" delivery of approximately 24 to 28 weeksA customer's individual requirement may also impact the estimated delivery schedule outlined above. It would be best to contact the sales department with your delivery requirements.
- 3. If I opt to repair a bearing rather than buy new, how much money will I save?
The estimated savings on a repaired bearing can vary from 40% to 70% over the cost of a new bearing. The level of repair will dictate the amount of savings to expect. For instance, repairs that require a thorough cleaning and polishing of the bearing components could result in savings as much as 70% to the customer. A more detailed repair, consisting of regrinding raceways, supplying new rolling elements, and cleaning and polishing all over would result in savings of approximately 45% to 50%.
Repair and Service
- 1. Does Kingsbury provide service and repair for non-Kingsbury products?
Yes. Kingsbury has extensive experience troubleshooting, replacing, or repairing all makes and models of fluid film, babbitted thrust and journal bearings.
- 2. Is there a charge for sending back parts for inspection and possible repair?
No. In most cases, the customer is repsonsible for the transportation of the parts to and from our facility. Standard incoming inspection is normally sufficient for Kingsbury to determine a repair/replace quotation, for which there is no charge. Kingsbury only asks that you contact us to give us any background information and to provide you with a reference umber for identification. Kingsbury will not perform any work until authorized to do so by the customer.
Often, Kingsbury will be able to make some determination based on photos and some basic information that can be provided by the customer without even shipping the parts to us.
In the rare case in which more detailed inspection/dissassembly is required, or if requested to perform special inspections for the customer, Kingsbury will provide a proposal to do so prior to performing the work.
