SPF  Bushings Graphite CuZn25Al5 Brass Bushing bronze case with graphite nests Bronze Bushing Saves You Time & Money In Research, Design & Production Costs. E-mail Now! Wide Variety & Selection. Oilless Bushing & Bearings. Expert Customer Service.

 

SPF  Bushings, made from Graphite CuZn25Al5 Brass Alloy, are precision-engineered components designed to offer exceptional wear resistance and self-lubricating properties. The unique combination of graphite, copper, zinc, and aluminum in the alloy creates a highly durable and low-friction surface, ensuring smooth and efficient operation in various industrial applications.

The self-lubricating nature of these bushings eliminates the need for regular lubrication, significantly reducing maintenance requirements and operational costs. The graphite content acts as a natural lubricant, providing a constant lubricating film that reduces friction and wear.

The CuZn25Al5 Brass Alloy material is chosen for its excellent corrosion resistance and mechanical properties, ensuring a long service life even in harsh environments. The bushings' precision manufacturing guarantees a perfect fit and optimal performance in high-wear applications.

Wh used in machinery, equipment, or vehicles, SPF  Bushings Graphite CuZn25Al5 Brass Alloy provide a reliable and cost-effective solution for maintaining smooth and efficient operation. They are an ideal choice for industrial applications that require high wear resistance and self-lubricating properties.

The standard graphite plugged bronze sleeve bushing is to open cavities of appropriate size and orderly arrangement on the metal friction surface of the bearing matrix, and then embed a molded solid lubricant with unique self-lubricating properties in the cavities (the solid lubricant area is generally 25% of the friction area -35%) and made of self-lubricating bearings.

The base body of the standard graphite plugged bronze sleeve bushing should be determined according to the working conditions of the bearing itself. The more commonly used materials are high-strength brass, tin bronze, castings and so on. There are two main types of embedded solid lubricating materials, one is natural black lead, artificial graphite, and MoS2 synthesis, and the other is synthesized with as the matrix. According to the bearing's own operating conditions, the combination of different metal substrates and embedded solid lubricants can ensure that the product can meet the special needs of various temperature, load, motion and media operating conditions, while ensuring stable and reliable operation.

Self Lubricating Bushings, Oilless Bush Supplier From China

 

We are a leading manufacturer and supplier of Oilless Bushing and our product is composed of good quality.

 

The oilless bushing, integrated into solid lubricants without oil, is a new type of solid copper alloy, which is homogeneously integrated with a solid lubricant in its body.

It breaks the limit of the general bearing, the lubrication of which depends on the oil film.

So it is suitable for high temperatures, heavy use, corrosion protection, or when oil is difficult to import.

Its performance doubles on both hardness and wear-friction.

Now it is widely applied in successive casting machines, steel rollers in metallography, mineral machines, ships, steam turbines, hydraulic turbines, and plastic injection molding machines.

 

 

JDB bronze graphite bush (oilless) sleeve bushing 50 x 62 x 50 mm long

 


Oilless Flange Sleeve Bearing Bushing, JDB material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal with stands high load and the solid lubricants provide for self-lubrication. Oilless Flange Sleeve Bearing Bushing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.

Oilless Flange Sleeve Bearing Bushing can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environments when no oil can be introduced.

Oilless Flange Sleeve Bearing Bushing is widely be used in automotive product line, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in metallurgy industry, mineral machines, ship turbo generators, hydraulic turbines and injection molding machines.

 

Oilless Bushing - Select, configure, order. Viiplus delivers punctually and offers fair prices.

Oilless Bushing Defined (What is oilless bushing?)

 

A oilless bushing, or more commonly sliding bearing and slide bearing, is the simplest type of bearing, comprising just a bearing surface and no rolling elements.

 

 

Oilless bushing can refer to ball bearings or just "rings" that do not require periodic lubrication - because a lubricant such as powdered graphite is incorporated into the material the bearing is made of. These are also known as Embedded Graphite Bronze Bushes and have 20-25% graphite inserts on the walls / surface which provide lubrication at all times which also reduces the coefficient of friction.

 

These oilless bushings are suitable for dry environments where contamination is a risk, wet applications where there is high humidity and applications where the bearing is in an inaccessible location.
