Cone Crusher Trust Bearing

Product Introduction

Cone crushers are widely used in mines, quarries and sand and gravel plants to crush rock, ore or minerals into smaller sizes. They work continuously so parts, especially wear parts, can degrade quite fast. When you put such machines and conditions together, the risk of mechanical malfunction, overheating and part degradation increases exponentially. In fact, improper handling may be responsible for up to three-quarters of machine failures.

When you decide to replace or source thrust parts for cone crushers, besides looking at the price you also have a number of other factors, for instance:

You will want to know if there is a match for the thrust bearing with regards to the crusher model and the OEM part number.You will also consider if the material type and dimension are able to withstand the operating conditions.Another issue is: do these bearings, if loaded continually, keep the surfaces together stably?One major cause of breakdown of a machine is wrong size of bearings, poor assembly or lack of regular lubricants.You will ask for verification through inspection reports of size and materials.The availability of spare parts consistently, especially through the years, is a big concern as well.

Our post-sales records and maintenance history suggest the root causes for problems with thrust bearing include incorrect component matching, wrong clearance, lubrication issues, uneven load sharing or excessive wear

• Higher axial clearance or shaft vibrations

• Ridged/uneven/crankshaft-type wear or the thrust pad and sheet

• Abnormally high temperatures

• Debris or copper shavings in oil

• Oily pressure variations related to bearing or lubrication conditions

• Less productivity and more time spent maintaining equipment

Product Solution

The set of thrust pads and thrust sheets by our company is used as a coordinated friction couple in the thrust bearing of cone crushers. Our production process for the mating thrust components involves manufacturing and checking them against confirmed drawings, OEM numbers, and specific customer requirements for each crusher model.

The solution mainly involves:

Dimensional matching: We make sure the level of flatness and parallelism, as well as the assembly dimensions, meet the standards of the approved engineering drawing.

Material selection: We follow the application and mechanical properties to pick the alloy and copper-alloy materials as specified.

Thrust-surface control: Close cooperation between machine shop and quality inspection to ensure consistent contact of mating friction surfaces.

Load distribution: Where applicable, contact pressure and local edge loading are assessed through engineering analysis to ensure safe contact between parts.

Quality verification: The finished goods will undergo a pre-shipment check on dimensions, hardness, surface condition, and other agreements based technical features.

Actual performance is strongly influenced by the model type of crusher, axial load, rotating speed, lubrication, assembly clearance, installation and maintenance conditions. Compatibility and specification of parameters must be checked against the relevant OEM part number or drawing before production.

Key Technical Features

Flatness: In general, thrust friction surface is the primary one, which can be finished with precision grinding to Ra ≤ 0.8 μm; however, the actual surface finish depends upon the confirmed product specification and inspection method.

Friction properties: Friction coefficient testing is performed under the specified oil-lubricated conditions only. The obtained test result along with the test method should be checked against the actual test report and test equipment.

Loading of parts: Load application on the bearing surfaces can be assessed by engineering analysis which includes, if relevant, finite element analysis. Thus, the loading of the thrust surface and the identification of potential stress concentration areas can be achieved.

Load: Load carrying capacity is different for each model of crusher, depending upon a combination of factors which mainly cover bearing sizes, material, speed of rotation and lubrication conditions; therefore, the suitable axial load shall be fixed only for one model not a universal value.

Size of parts: Measurements for flatness, parallelism, thickness along with assembly dimensions are done referring to the confirmed drawing and the agreed set of tolerance requirements.

Material and hardness: Material grade and hardness are set within the limits established by the validated technical regulations and the inspection conditions.

The results obtained from the performance data can only be understood in the context of the relevant crusher model specifications, test environment and inspection report details.

Cover Product Advantages:

1. Stable and Efficient Operation

An improved composite material formulation and precise machining reduce mechanical friction loss and minimize the rise of operating temperature even during long heavy-load operations. In actual comparative tests, these features helped to decrease friction loss by about 35% and heat generation by about 28% under the same operating conditions.

2. Longer Maintenance Interval

Under highly abrasive conditions, our thrust bearings suffer less wear than standard ones. Through real-life testing, the spindle and support frame matching parts have demonstrated a greatly improved lifecycle resulting in lesser annual replacement and consequently reduced maintenance costs.

3. Flexible and Widely Applicable Solution

Our solutions cater to most popular cone crusher brands and sizes across the market. We provide both mass production according to standard samples and bespoke solutions based on client’s drawings. We confirm the customized drawings within 3-7 business days after the technical details are sorted out.

Note: Kindly supply the OEM part number and equipment model in order for us to determine parts compatibility.

4. High Supply Capacity

Above 200 sets of standard specifications parts, which represent the most popular types used in practice, are always stocked. Items in stock will be shipped within 24 hours after your order has been confirmed. For rush orders, up to 95% of products can be shipped within 48 hours, depending on availability and the production schedule.

P.S.: For parts on custom basis, shipping time needs a separate verification.

Data Reference Note

These percentages have been made by combining internal lab tests and field data collected from some of our customers. Please keep in mind that even though they look very encouraging, a warranty of the same performance under all situations is not a reality. In fact, they just give a guideline of potential performance under different types of service conditions. If you need confirmation on how the products will behave in your specific conditions for a particular type of machine that you use, do not hesitate to ask us for it. Our technical team can definitely provide the most accurate and tailored estimate.

Product Application:

This line of thrust parts is mainly used for heavy-duty and abrasive conditions of the cone crusher. It usually works at axial load of around 500~1200kN according to model and application conditions.

Applications

- Crushing for mining

- Quarry processing

- Construction aggregate production

- Road and bridge engineering projects

- Industrial raw materials crushing

- Cement and metallurgical plants

The product allows for continuous work and also unplanned stops in the production cycle. Actual production continuity largely depends on the complete crushing system, maintenance, lubrication and work conditions.
