“bronzelube.com” has since established itself as a leading distributor of Bronze, Copper & Brass, Iron, Sintered Products, Self lubricated bushings and Wear plate, in China. We Are Specialists In Cutting Lubrication Grooves In Virtually Any Pattern. Self-Lubricating, Fast, Reliable With Highest Quality Standards.Bronze bushings with oil grooves, grease grooves in bushings!
Made-To-Order Groove Bronze Bushing For Oil Application
Circular oil grooves bronze bushing. Our Groove Bronze Bushings are machined from continuous cast bronze for superior quality and performance. The continuous casting process assures a uniform bronze structure throughout the bearing, free from porosity and hard particle inclusions commonly found in other cast processes.

Bronze Plain Bearing, Groove Bronze Bushing
RG7 (CuSn7ZnPb) circular oil grooves RG7 Bearing Bronze made to order from china.
Grooves are often machined in plain bushes to improve the lubricant flow and therefore the sliding properties of the bush. Grooves also aim at carrying of the wear wastes from the sliding surface.
Mechanical Characteristics, High quality at cost-effective prices.
The groove bronze bushing with a single oil hole can have approximately three times the load bearing capacity then a bearing with an annular or circumferential groove in the same length bearing.
The oil groove of the oil groove of the copper sleeve is some inside the copper sleeve, and some outside the copper sleeve. Its oil groove is generally processed directly by lathe milling machine or NUMERICAL control lathe. Different processing techniques can be selected according to different forms of oil groove.
*In order to form a more perfect oil film between the bearing & shaft, we recommend a V-shaped groove whenever the design permits, as it allows full flow of the lubricant across the bearing surface.

ASSEMBLY ADVISE: Lubrication Bearings
Graphite Bronze Bearing is maintenance-free but lubricating the sliding surfaces during assembly is recommended for initial start-up period. Common lubricants such as greases or oils can be used. For optimal performance and longevity, it is important that mating surfaces are properly cleaned when assemblying.
RANGE OF APPLICATION
Hardware and steel fabrication, stamping dies, tooling components for the automotive industry, sheet pressing etc.
