Product Description

Components for Press Dies, Oilless Bronze Bushings Size & Catalog

 
The first cost-competitive alternative to C93200 (SAE660) bronze bearings.

 

Owing to the high quality and variability, our oilless bushes are widely used in the automobile, engineering, electrical and consumer goods industries. Quality is the number one characteristic, which our business partners expect from our sliding bearings products. We endeavor to offer more – customer care, technical service, and guidance – which our business partners receive together with high-quality materials for injection molding.

 

Oilless solid lubricant embedded bushing is made from strong material and homogeneously embedded with solid lubricant in its body.

 

It breaks through the limit of general bearing whose lubrication depends on an oil film.

So it is suitable for high temperature, heavy-duty, anti-corrosion, or where oil is hard to be introduced.

It′s performance doubles both on hardness and wear-friction. It is now widely applied in successive Casting Machines,

 

We Manufacture • Stock • Distribute

Typically there are 3 Standard Types of Bushings:

Sleeve Bearing
Flange Bearing (Double Flange bushing also)
Thrust Bearing (also called a Thrust Washer)
Each type is available as a Plain Bearing, Grooved (Oil or Grease), and/or Graphite Plugged Bearing.

SOLID LUBRICANTS

 
available high-quality bronze alloys. Embedded in this structure are solid lubricant inserts or plugs, providing continuous lubrication for low friction and wear rates and long service life.

2. Solid lubricant inserts
3. Bronze
Bronze Bearing forms made to order: cylindrical bushes, flanged bushes, thrust washers, sliding plates, customized bearing designs


Graphite impregnated bronze - Bearing Types

 
Corrosion resistance depends largely on the lubricant, bronze bearing, and mating surface materials. Graphite plugs bronze bearings should never be used where electrolytic corrosion can occur, such as high humidity atmospheres or submerged equipment. In this case, PTFE-based plugs are recommended
Oilless Flange Sleeve Bearing Bushing High hardness impregnated brass solid lubrication bearing is improved upon Oilless Flange Sleeve Bearing Bushing by further enhance the hardness of high hardness brass, giving rise to higher load-bearing capacity and better wear-resistant property. The products are widely used in continuous casting rolling machines, mining equipment, engineering equipment, injection-molding machines, etc. Because of its high hardness, it's difficult to machining and finish, it's recommended only for really high load applications.
 

Basic material CuZn25A16Fe3Mn3 Dynamic load 120N/mm²
Base hardness HB210~275 Friction Coef <0.16
Temperature Max 300℃ Speed limit dry 0.4m/s oil 5m/s

 

Material Features

 
Oilless Flange Sleeve Bearing Bushing, JDB material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands 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 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 Flange Sleeve Bearing Bushing​ fixing method

 

When pressing the oil-free bushing, use a vise or punch to press it in quietly. In order to facilitate the press-in, it is recommended to chamfer the end of the inner diameter of the fixed seat, apply a small amount of lubricating oil to the inner diameter of the fixed seat and the outer diameter of the bushing.

 

Anti-rotation screw/bonding

 

Note that when the oil-free bushing is prevented from falling off and turning, it is recommended to use the following methods depending on the conditions of use and the environment.

Oilless Flange Sleeve Bearing Bushing

The life of oilless bushings depends on the amount of wear. The calculation of wear amount is very different due to surface pressure, sliding speed, movement pattern, lubrication conditions, the surface roughness of the matching shaft, and other conditions. From the viewpoint that the wear amount is proportional to the load and sliding distance, the following formula is usually used to calculate the wear amount. Please consider it as the standard for selection.
Estimate wear(mm)W=K*1×p×v×T
Wear ratio(k):mm/(N/mm2·m/s·Hr)
Design surface pressure(p):N/mm2
Sliding speed(v):m/s
Friction time(T):Hr-hr
