Bimetal Bearings:

We re specialized in thin antifriction bearings and notably connecting rod bushings and engine bearings with or without flanges.

bimetal bearings are manufactured through two distinct types of production: either from a steel backing with a sintered bronze layer or from a steel backing with a white metal layer. Additional layers made of lead or nickel may complete the product’s characteristics.

Cylindrical solid and slotted bushings: Slotted rolled sliding bushes, with or without gasket with a closed or open slot, are the result of a rolling and shaping process on steel + sintered bronze sheets. These sliding sleeves can also be closed by laser welding or by stapling. Whatever the configuration, they always have high level mechanical and dynamic characteristics. All bushings can be fabricated with one or two flanges. On non-split solid slip rings, the bronze or tin layers are applied using a conventional fusion process. Split Bushings are: specifically with Steel backed bushing as base material on which a highly resistant anti-friction metal fabric.

A bi-metal bushing, specifically one with steel backing and a lead-bronze alloy overlay, is a specialized type of plain bearing used in many different mechanical applications. Let’s break down the components of this type of bushing:

  1. Bi-Metal Bushing: A bi-metal bushing is a type of plain bearing that combines two different metals for enhanced performance characteristics. The idea is to maximize the benefits of each metal. In general, one metal is used for its superior strength and durability, while the other is used for its superior friction and wear characteristics.
  2. Steel Backing: In a bi-metal bushing, steel is typically used as the backing material. Steel is chosen for its exceptional strength and rigidity, which provides excellent support for the bearing and helps to ensure its structural integrity under heavy loads. The steel backing also helps to absorb shock and vibration, and is resistant to fatigue.
  3. Lead Bronze Alloy: The bearing surface of a bi-metal bushing is often made from a lead-bronze alloy. This alloy is chosen for its superior sliding and wear characteristics. The lead in the alloy improves the material’s ability to conform to irregularities on the shaft and provides excellent embeddability, while the bronze provides good resistance to wear and corrosion.

This combination of a strong steel backing with a lead-bronze alloy bearing surface makes the bi-metal bushing ideal for applications with high loads and harsh conditions. Such bushings are often used in engines, gearboxes, agricultural machinery, and other types of heavy-duty machinery.

As always, the specific performance characteristics of a bi-metal bushing will depend on the exact composition of the lead-bronze alloy and the specifics of the design and manufacturing process. Therefore, it is important to work with a reputable manufacturer or supplier who can provide the necessary technical support and quality assurance.

Inner wall material performance:

CuPb24Sn4: has high fatigue strength and bearing capacity, impact resistance, but because of the high lead content in the alloy and high density are prone to lead segregation, and reduces the abrasion resistance of the bushing at the same time also makes the combination of alloy layer and steel back strength is reduced, the high cost of the copper layer used in high speed, swing and rotating wages under the condition of bearing.

CuPb10Sn10: have high fatigue strength and bearing capacity good lubrication performance, wear resistance and corrosion resistant performance is good, suitable Yu Zhongzai, medium to high speed and has a larger impact load-bearing, mechanical equipment on the use of rolling bearing, the gasket surface pressure is high, and there is the lateral pressure of the sliding bearing, such as rolling, vehicle use bearing, bimetallic bearing shell, and the piston pin set, lining, etc.

CuSn6Zn6Pb3: Good wear resistance and corrosion resistance, easy to process, good casting performance and airtightness, working under general load, medium sliding speed, such as turbine, motor, compressor, piston clutch, connecting rod bushing, rocker arm bushing, etc., the current consumption is relatively large.

Cusn6.5-0.1: Lead-free bimetallic bearing is widely used in the balance axle bushing, gasket, internal combustion engine spindle bushing, connecting rod bushing, rocker arm bushing, oil pump side friction plate, internal combustion engine bushing of medium and small power, train engine bushing, air press bushing, refrigerator, etc.

ALSn20Cu: With moderate fatigue strength and bearing capacity, good corrosion resistance, and sliding performance. It can be used with the soft shaft and is often used for small and medium power internal combustion engine bearing bush, train engine bearing bush, air compressor bearing sleeve, etc. It is the best product to replace bimetal alloy.

Steel Backed Bushing Bearings

Steel-backed bushing bearings are our standard replacement parts. Our steel-backed bushing with bronze, which provides excellent bonding qualities for applying the bushing lining. Bronze is a perfect bearing material–tough enough to withstand the loads and demands of rotating equipment but forgiving enough to not ruin a crankshaft in the event of a failure.

Bronze Lined Bearings/Wrapped standard bearings

The lining of these bearings is a bimetal metal. This lining is applied at the optimal thickness to ensure the best fatigue resistance and ability to embed small particles of impurity from the oil. Our industry experts can deliver high-quality steel-backed bronze bearings at the unbeatable price you’ll like.

Characteristics

The JF bi-metallic self-lubricating bearing uses a high-quality low carbon steel plate as the base, porous sintered bronze as the surface, suitable for oscillating and alternating rotary movements under high load conditions. Slow speed, low friction, good resistance wear, long life, and better prevent snagging. The surface of the bronze layer can be machined with various grooves, oil pockets in terms of different working conditions. The product is widely used in mining machinery, automotive, construction machinery, agricultural equipment, the steel rolling industry, etc..

Metal, Bimetal & Steel Bearings

Series bimetallic bearing material, also steel-backed bronze lined materials lead or copper strip, is based on low carbon steel or steel as substrate material, the surface of sintered copper alloy steel and copper alloy products, different kinds of copper alloy material is suitable for different working condition, based on the surface can be divided into different grades of copper alloy high lead series, series of lead and lead-free series.
