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.
