Connecting Rod Bimetal Sleeve Bushes made of Steel-CuPb30 alloy are precision-engineered components designed specifically for the 700 series engines. These bushes feature a bimetal construction, combining the strength and durability of steel with the wear resistance and self-lubricating properties of CuPb30 (copper-lead alloy).

The lubricating grooves strategically positioned within the sleeve bush allow for the retention and distribution of lubricant. This ensures continuous and even lubrication during the operation of the connecting rod, reducing friction and wear on the sliding surfaces. The lubricant, often oil or grease, is supplied to the grooves either through an external lubrication system or via the reciprocating motion of the connecting rod.

The Steel-CuPb30 alloy is chosen for its excellent bearing properties and ability to withstand high loads and temperatures. This combination of materials ensures that the sleeve bushes provide reliable performance in demanding engine applications.

For the 700 series engines, these sleeve bushes are an essential component, ensuring smooth and efficient operation of the connecting rod assembly. Their precision fit and lubrication grooves contribute significantly to the overall performance and durability of the engine.

About VIIPLUS We Are Supplier Of Bimetal Bushing Parts For Connecting Rod & Camshaft Bushes With High Quality Unebatable Pricing And Customer Value.Bi-metal Bearings_SAE 797, SAE 799, SAE 783, SAE 48, SAE 49 Bi-metallic composite bearings to high-quality low-carbon steel substrate, the surface of the sintered copper alloy with low friction characteristics (CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) as bearing wear layer ......The sleeve steel bronze bushings & bearings-700 bearings made to order from china are bimetal sliding bearings with a steel strip and sintered CuPb30 as the surface sliding layer. These sliding bearings have good anti-locking protection and a high proportion of lead, meaning that they can bind more dirt particles and impurities, thereby preventing a seize-up.

bimetal bearing is made of steel sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer.This type of bushing show its best performance among bushings made of Cu-lead alloy material in this product range.It suits most for middle speed and high impact conditions.Its application including balance suspensions of heavy-duty trucks, track roller of bulldozers,auto chassis etc.

Bimetal Sleeve Bushing consists of a high quality low carbon steel backing carring a sintered tin-lead-bronze alloy (CuPb30) as a sliding layer. In order to improve tribological behavior the sliding layer can be machined with lubricating grooves for oil- or grease storage and distribution. In case of corrosive environment the backing can be copper plated. bimetal sleeve bushings is used for wrapped bushes, thrust washers and bushes in connecting rods of gas engines, etc.

Plain Bimetal Bearings Typically Used In Truck Trunnon Shaft, King Pin Kit, Connection Rod, Rocker Arm, Leaf Spring, Cam Shaft, Crankshaft, Bulldozer And Excavator Track Roller, Carrier Roller, Idler Etc.

Bimetal self-lubricating bearings reduce noise and stickiness.In addition, its matching shaft material reduces wear and extends service life.The VIIPLUS solution is the same size as copper bearings, but reduces the need for expensive improvements and retrofits.

Bimetal Bushing & Bearings Services. Description: sliding bearings. Bimetal wrapped cylindrical bushings ( DIN 1494 )

VIIPLUS bimetal bearings take steel backing as base The
bearings are sintered with CuPb10Sn10, CuPb24Sn4,CuPb30, CuSn6Zn6Pb3 or AlSn20Cu after press. It can insure the bearings O.D. Precision against the friction between O.D. And housing after pressing it into housing because of mild steel as its base. The chemical changes of inner alloy layer can make the bearings work well under various load presses, different working temperatures and sliding speeds. Different structures of oil grooves and oil Indentations can satisfy different adding oil ways andprevent the bearings from gripping shaft.

The structural characteristics

Bimetal composite bearings with high quality low carbon steel as substrate, the surface of the sinter with low friction properties of copper alloy (CuPb10Sn10 CuPb6Sn6Zn3 CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) as wear-resisting layer of bearing, can need according to the operating conditions of copper alloy surface processing of various types of oil tank, oil hole, hole, etc., in order to suit to cannot continue to go hard or go occasion.Good joint strength and optimum bearing capacity can be obtained by the secondary sintering and extrusion.

Description

Bimetallic self-lubricating bearing (foreign says deva. Bm) is a high quality low carbon steel, bronze sheet or stainless steel plate as substrate, spherical bronze powder as middle transition layer on the surface, at the same time to sintering rolling with solid lubricant (graphite) copper alloy as friction surface layer of a kind of self-lubricating composite bearing material, the rolling and sliding bearing.The material has the advantages of self-lubrication, high bearing capacity, good anti-friction and wear-resisting performance, applicable temperature, wide range of medium, simple structure, compact size, and can work in the condition of non-oil lubrication for a long time.

Bi-metallic composite bearing material consists of steel backing with lead bronze or lead-free copper alloy
