SAE 660 tin bronze is mainly used for bearings, bushing under moderate load and speed, general-purpose bearings, bushing, and wear plate.
SAE 660 tin bronze copper sleeve has excellent machining performance, good hardness, strength and wear resistance, excellent anti-friction performance. The alloy is non-de-zincing, with reasonable corrosion resistance to seawater and brine, suitable for pump and valve parts, SAE 660 bearing bronze copper sleeve, high lead-containing tin bronze, 83-7-7-3 ASTM B 505, ASTM B 271
Plug graphited is accomplished by drilling a rowed, staggered hole configuration through the bearing wall and pressing graphite into these holes and hard baking. The size and number of drilled holes and the number of rows is determined by the bearing length and diameter.
Graphite Plugged Bronze Bushings are all self-lubricating and maintenance-free. These bushings are machined out of continuous cast bronze and plugged with solid lubricant plugs. A bushing and its mating surface should always be separated by a film of lubricant. Many of VIIPLUS’s components use graphite. Here is what you need to know about it. Graphite is ordinary carbon in a highly unusual form, a two-dimensional crystal. Think of it as a one-atom-thick sheet. A piece of graphite is a stack-up of these sheets. A graphite pencil lead feels oily because these one-atom-thick sheets are very slippery.

1. Design the initial lubricating film as required to reduce the initial friction factor.
2. Solid lubricant, which is embedded and arranged regularly according to the movement direction, is released to the surface of the bearing during operation to form a solid lubrication film, which can reduce the friction factor and improve the wear resistance.
3. High strength copper alloy provides a bearing substrate with bearing capacity and good impact resistance and corrosion resistance.

Graphite Plugged Cast Bronze Bushings can be utilized where heavy loads must be supported at low to medium speeds
The Plug Graphite Cast Bronze Bushing is able to withstand high temperatures up to 570 F
The self-lubricating feature allows bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.
Self lubrication with specially embedded solid lubricants reduces friction. Coefficient of Friction: 0.04 to 0.2
That reliability of the grease-lubricated sleeve bearing must be increased.
The installation and disassembly method of excavator bearing shall be determined according to the structure, size and matching nature of excavator bearing components. The pressure of mounting and disassembling shall be directly added to the end face of the closely matched gear ring of the excavator bearing, and the pressure cannot be transferred through the rolling body of the excavator bearing, because this will cause indentation on the working surface of the excavator bearing, affect the normal work of the excavator bearing, and even damage the excavator bearing. The retainer, seal ring, dust cover and other parts of the excavator bearing easily deform, and the pressure of installing or removing the excavator bearing cannot be applied to these parts. Excavator bearing installation: (1) the shift device is not properly adjusted if the transmission of this type of excavator is mechanical manual shift mode if the shift lever, vertical axis, horizontal axis, and vertical fixed screws loose can also cause the transmission "shift". (2) A sudden change of external load Due to the working nature of the excavator and its own design reasons, the sudden change of external load will also cause its transmission "jump gear". When the uneven road surface, excavator for driving downhill or improper driving route to make the external load suddenly change, the sudden change of the load will be through the wheel, the transmission shaft acting on the gear gear gear gear gear gear gear gear gear gear gear gear for the generation of axial thrust and off, resulting in the transmission "jump block". Performance degradation of self-locking mechanism (3) The transmission mechanism of the gear shifting device of the excavator relies on the sliding gear sleeve to move axially on the fixed gear sleeve and meshing with the driven gear of each gear to realize the gear shifting. In the process of frequent gear shifting, the gear tooth end face of each meshing gear is easy to be ground into a cone shape, resulting in its meshing performance degradation and resulting in "jump gear". (4) to prevent "jump out" of the transmission, excavator in transmission Ⅱ, Ⅲ cover, and Ⅳ Ⅴ fork shaft at the top of the box cover hole and Ⅰ, reverse gear fork are self-locking Ann has the function of steel ball and spring. When the spring from the role of the positioning of the self-locking elastic weakened or broken, the self-locking mechanism of the self-locking performance will decline until it disappears, causing the transmission "jump block". At the same time, if the groove on the positioning ball or shifting fork shaft appears to wear, it also can cause the transmission "jump block". (5) Improper operation Method When the excavator is running on the ramp (especially running downhill), improper operation will also cause the transmission to "jump into gear".
High strength copper alloy provides the bearing's mechanical bearing capacity, and lubricant can provide the bearing surface with a continuous source of lubrication to form a good friction pair. Suitable for medium and high load, starting frequently can not add oil or difficult to form oil film occasion. Typical applications include curved elbow bearings for plastic machinery, green column guide sleeve, port machinery, sluice gate for hydraulic engineering, mining equipment, etc.
