Cone Crusher Bolt

Replacement Challenge & Solution

Replacing worn cone crusher bolts can be difficult when original drawings or part numbers are unavailable. Variations‍‌‍‍‌ among crusher models and installation positions mean that thread specifications, lengths, and head styles may vary accordingly. If you match and buy a replacement by its looks alone or by basic dimensions, it might result in the wrong matching and installation ‍‌‍‍‌problems.

First‍‌‍‍‌ Shenyang Zhuoyue goes through various forms of data including crusher models, part numbers, drawings, physical sampling, photographs and measurements. They use this information to identify and double-check the bolt specifications needed for the manufacturing process. Once the details have been confirmed, the customized manufacturing begins. This method enables them to perform thread machining with accuracy as fine as ±0.01 mm and so, they can be certain that the parts fit accurately and that the risk of having to replace them later is ‍‌‍‍‌minimized.

Product Advantages

1. High Strength for Heavy-Duty Applications

The‍‌‍‍‌ combination of 42CrMo high-strength alloy steel with an integral forgong heat treatment process enables cone crusher bolts to reach a tensile strength over 1080MPa plus a hardness of HRC42–48 which is perfect for enduring heavy loads and vibrating ‍‌‍‍‌environments.

2. Precision Machining for Reliable Fitment

Thread‍‌‍‍‌ machining by means of threads not only ensures the high precision with the dimensional difference being up to 0.01mm but it also helps to preserve the quality of installation even in the situation when the component has to be ‍‌‍‍‌changed.

3. Strict Quality Control for Consistent Performance

Bolts‍‌‍‍‌ of Cone Crushers are being checked by an elaborate inspection that includes material composition analysis, checking of heat treatment done, precision checking of taps in the thread, hardness as well as tensile strength of test are done. The rate at which the products are considered to be meeting the specifications is 99.7%, salt spray resistance according to product requirements is more than 500 ‍‌‍‍‌hours.

Product Types

· Hex Cone Crusher Bolt

Suitable‍‌‍‍‌ for use with devices that require a hexagonal head configuration, the thread dimensions, the total length, the thread length, and the head dimensions are all made to the relevant ‍‌‍‍‌specification.

· Hammer Head Bolt

Such‍‌‍‍‌ types are suitable for use when a formed head is part of the design. The head size, thread size, and total length are variables set at the user's discretion and are subject to the corresponding technical ‍‌‍‍‌conditions.

· Custom Cone Crusher Bolt

If‍‌‍‍‌ you have special size, screw, head, material, machining requirements, these can be customized based on your confirmed product drawing ‍‌‍‍‌specifications.

Technical Specifications

Final dimensions, material, and processing requirements are confirmed before production.

Key Points for Replacement Specification Confirmation

It‍‌‍‍‌ should be identified through the actual equipment together with the available technical data rather than merely by appearance which is usually unreliable for identifying suitable replacement parts, therefore, identifying the right bolt must come from the accurate ‍‌‍‍‌information.

1. Crusher Model & Installation Position

Different‍‌‍‍‌ types of machines or the way they are installed may require different sizes or even different head ‍‌‍‍‌designs.

2. Thread Dimensions

Thread diameter, thread pitch, thread length and total length, have to be checked all together to determine the required connection ‍‌‍‍‌specification.

3. Head Configuration & Dimensions

The‍‌‍‍‌ head type and size have to meet the correct requirements for installation. Depending on the technical details provided, hex, hammer head, or other special types may be ‍‌‍‍‌considered.

4. Material & Processing Requirements

Material requirements should be considered together with the bolt configuration. Heat treatment and surface treatment can also be included when required by the applicable specification. 42CrMo can be considered when required by the confirmed specification or customer requirements.

5. Available Reference Information

A complete technical drawing is not always necessary to begin a replacement specification review.

· Crusher model

· Original part number

· Physical sample

· Product photos

· Key measurements

· Technical drawing

· Other available technical information

The available information is reviewed to determine which specifications need to be confirmed before manufacturing.

Material, Manufacturing & Quality Control

Material‍‌‍‍‌ choice is determined by the verified product specifications and the requirements for its use. For example, if a higher strength material is required, 42CrMo alloy steel can also be considered.

The bolt design determines the production process, which can be a combination of forging, machining, thread rolling, heat treatment, and surface treatment. These steps will also depend on the bolt ‍‌‍‍‌design.

Quality‍‌‍‍‌ inspection shall be carried out in accordance with the approved specifications and quality requirements, including:

· Analysis of material composition

· Heat treatment examination

· Thread accuracy examination

· Drawing dimensional inspection

· Hardness testTension strength test

Where appropriate thread accuracy can be checked according to the ISO 6g requirement. What to inspect is decided according to what specification and quality requirements are ‍‌‍‍‌applicable.

Ordering & Delivery Information

MOQ

Customers‍‌‍‍‌ may order standard products in quantities as low as 1 piece if the product is in stock. For special order production of parts which are out of the standard design, the minimum quantities required are usually between 30-50 pieces per production batch and will depend on the level of process complexity as well and the specifications of the ‍‌‍‍‌orders.

Packaging

Crusher‍‌‍‍‌ parts are generally packed in wooden boxes. The packaging is chosen based on the product size, quantity, and transportation ‍‌‍‍‌requirements.

Lead Time

The‍‌‍‍‌ amount of lead time varies according to the bolt configuration that is finally confirmed, type of material used, quantity of the order, machining specifications, and production timeline. Delivery schedule is finalized upon checking product specification and order ‍‌‍‍‌requirements.

Shipping Terms

EXW and FOB can be discussed according to order requirements.

FAQ

1)If I don't have the original drawings, can you help me choose a suitable replacement bolt?

If you have physical samples, photos, size data, machine model number or original part number, we can also help you.

2)‍‌‍‍‌ What sizes you have to think about when you get a new bolt?

Thread diameter, pitch, length of thread, bolt length and the size of the head are basic parameters for choosing a fastener. Also be sure to identify the crusher brand and model and the spot the installation will be carried ‍‌‍‍‌out.

3)‍‌‍‍‌ Are you able to make non-standard cone crusher bolts?

Sure thing. All non-standard sizes and configurations can be manufactured at our plant if you confirm all technical requirements to us. You can also use drawings, physical samples, photos, measurements or other technical documents as ‍‌‍‍‌references.

4)‍‌‍‍‌ What is the MOQ for cone crusher bolts?

If standard products are available from stock, they can even be bought one by one. For customized, non-standard parts, the MOQ is usually around 30-50 pieces per batch depending on the complexity of the production process and the requirements of the ‍‌‍‍‌order.

5)‍‌‍‍‌ How is lead time determined?

The main factors that determine lead time are bolt configuration, material, order quantity, machining requirements and production schedule, etc.

The final delivery schedule will be confirmed after the product and order requirements have been reviewed ‍‌‍‍‌together.
