Powdered Metal Parts

DBM offers a complete line of Standard SAE 841 Powdered Metal Bearings including plain sleeve, flanged and thrust washers.  For proper lubrication, we use the highest quality SAE 30 oils available. Our standard lubricant has an effective operating range from +175ºF to +220ºF.  Applications requiring extended or unusual operating ranges must be identified so that we can select a special lubricant to do the job. This impregnation process is available for a minimal charge

Choose from three types of SAE 841 Parts:

Storage of Bearings –These bearings must be stored in non-absorbing containers.  Do not store in paper or cloth container. Do not store in cardboard boxes.  The best containers are made of plastic or metal.

Supplementary Lubrication Additional lubrication can be provided through the use of oil soaked felts, wicks, etc. or by periodic oiling. A unique advantage of this type of bearing is that it does not require any grooving or holes to distribute the oil across the bearing face due to the microscopic pores in the bearing material.

*Custom Made Bearings Custom powdered metal bearings can be designed and manufactured according to customer specifications, including requirements for special dimensions and/or materials.  Please call or submit your drawings and we will produce a quotation quickly.
