Oil Embedded Sleeve Iron Bearing
DALON self-lubricating sintered bronze bushing are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity (20-25% in volume). The oil contained in the porosity provides a constant lubrication between bearing and shaft, the system does not need any additional external lubricant, allows this type of sintered bronze bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

Storage of SAE 841 Bronze Sleeve Bearing – 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 SAE 841 Bronze Sleeve Bearing – Custom SAE 841 Bronze Sleeve Bearing can be designed and manufactured according to customer specifications, including requirements for special dimensions and/or materials. Please offer your drawings by email and we will made a quotation quickly.
We always insist on "survive by quality, promote development by integrity" and strive to create "integrity Oil Embedded Sleeve Iron Bearing". Wish we work together to create brilliance, as long as you call, we will do the rest! We keep up with the changes of the market and let the enterprise keep a foothold. We are willing to sincerely cooperate with foreign users with our excellent technical equipment, satisfactory quality, high quality service, flexible operation and fine reputation.
