C90800 Graphite Inlaid CuSn12 Bronze Bushing Bearings

Copper Bearing finished copper alloy bushings provide a simple, economical way to use bearings with high bearing, good corrosion resistance, dimensional processing any of the characteristics. Meanwhile VIIPLUS CHINA can provide different copper alloys according to different conditions, and in accordance with the requirements of processing different forms, it has a higher dimensional accuracy than class copper rolling bearings.


Bronze Plugged bronze bushing for High Temperature Applications. Reduced costs & downtime. Increased productivity. Highlights: Offering Custom Designed Products,Customized Drawings Available.Plug graphiting is accomplished by drilling a rowed, staggered hole configuration through the bearing wall and pressing graphite into these holes and hard baking.Standard size and custom size Choose from our selection of graphite bronze bearings wheel, including stock products in a wide range of styles and sizes.BEARING WHEEL C90800 Graphite Inlaid Oiles Tin Bronze Bearing Graphite

Application

Heavy Industries Steel Tube Plant Machinery • Tire & Paper Mills • Power Generating Stations • Injection Mold Machine

Our range of flanged bearings are available in metric and imperial sizes. Our in-house machining service is able to produce non-standard sizes to suit specific customer requirements.Plug graphiting is accomplished by drilling a rowed, staggered hole configuration through the bearing wall and pressing graphite into these holes and hard baking.

C90800 Bearing Bronze


We Offer the C90800 Bearing Bronze, cast bronze bushing & plate.

Viiplus graphite plugged tin bronze oiles bearing is based on tin bronze material. This type of self-lubricating bearing is also called #500 oilless bearing,brass bearing,cooper bushing,solid sliding bearing,guide bushing and graphite filled bearing.

The tin bronze graphite inlaid bearing is based on CuSn12 material. Compared with CuSn5Zn5Pb5, CuSn12 increases the tin content and reduces the friction coefficient, but the relative cost increases.The product is embedded with graphite oil as solid lubricant, which can achieve the effect of lubrication without oil.The product is mainly used in low load, relatively high temperature, medium speed occasions, such as construction machinery 'metallurgy machinery, paper machinery, transport machinery in the lubrication difficult parts.

Solid bronze bearing is a standard item of our company. This type self-lubricating bearing is also called solid metal bearing,graphite plugged bearing,solid lubricating bearing,guide bushes,cast bronze bushing, #500 oilless bearing,oiles flange bearing and solid sliding bearing.

Advantages

In places where oil film formation is difficult, such as reciprocating movement, swing movement, frequent starting and stopping, excellent wear resistance can be exerted:
The arrangement principle of the lubricants of the solid lubrication bearing is to ensure that there are lubricants on all parts of the grinding parts in the running process. Therefore, the arrangement position of the lubricants must be determined according to the movement direction of the grinding parts.

Clearance


Greater than normal clearance must be allowed: (1) if exceptionally high speed is involved, (2) if higher than normal loading is encountered.

Material Structure
Standard material: CuSn12 + Graphite.

Characteristics


● Have Incomparable performance under a high load, low speed operation. Also perform well without lubrication;

● Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations;

● Remarkable resistance to corrosion and resistance to chemical attack;

● Maintenance free and save operating cost.


Availability


● Cylindrical oiles bushing, flanged oilless bush, thrust washer and slide plate are standard fabrication.

● Special designed solid metal bearing and material can be made according to your design.

● Other material can be made based on your requirement.
