Cone Crusher Bolt

Replacement Challenge & Solution

Replacing worn cone crusher bolts can be difficult when original drawings or part numbers are unavailable. Different crusher models and installation positions may require different thread specifications, lengths, and head configurations. Selecting a replacement only by appearance or basic dimensions may result in incorrect matching and installation problems.

Shenyang Zhuoyue reviews available information including crusher models, part numbers, drawings, physical samples, photos, and measurements to confirm the required bolt specifications before production. Customized manufacturing is carried out according to the confirmed requirements, with thread machining precision up to ±0.01 mm, helping ensure accurate fitment and reduce replacement risks.

Product Advantages

1. High Strength for Heavy-Duty Applications

Manufactured with 42CrMo high-strength alloy steel and integral forging heat treatment technology, cone crusher bolts achieve tensile strength exceeding 1080MPa and hardness of HRC42–48, helping withstand heavy loads and vibration conditions.

2. Precision Machining for Reliable Fitment

Thread machining precision can reach ±0.01mm, ensuring accurate thread dimensions and helping improve installation reliability for replacement applications.

3. Strict Quality Control for Consistent Performance

Cone crusher bolts undergo professional inspections including material composition analysis, heat treatment inspection, thread accuracy inspection, hardness testing, and tensile strength testing. The product qualification rate reaches 99.7%, with salt spray resistance exceeding 500 hours according to product requirements.

Product Types

· Hex Cone Crusher Bolt

Available for applications requiring a hexagonal head configuration, with thread dimensions, overall length, thread length, and head dimensions manufactured according to the applicable specification.

· Hammer Head Bolt

Available for applications requiring a shaped head configuration. Head dimensions, thread details, and overall length can be established according to the applicable technical requirements.

· Custom Cone Crusher Bolt

Non-standard dimensions, thread specifications, head configurations, materials, and processing requirements can be customized according to confirmed product requirements.

Technical Specifications

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

Key Points for Replacement Specification Confirmation

For replacement parts, the required bolt should be identified based on the actual equipment and available technical information rather than appearance alone.

1. Crusher Model & Installation Position

The crusher model and installation position provide important reference information when determining the applicable bolt configuration. Different equipment models or installation positions may require different dimensions or head configurations.

2. Thread Dimensions

Thread diameter, thread pitch, thread length, and overall length should be considered together to establish the required connection specification.

3. Head Configuration & Dimensions

The head type and dimensions need to correspond to the applicable installation requirements. Hex, hammer head, and other custom configurations can be reviewed according to the available technical information.

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 selection is based on confirmed product specifications and application requirements. 42CrMo alloy steel can be applied when required.

The manufacturing process may include forging, machining, thread processing, heat treatment, and surface treatment according to the bolt design.

Quality inspection is carried out according to confirmed specifications and quality requirements, including:

·Material composition analysis

·Heat treatment inspection

·Thread accuracy inspection

·Dimensional inspection

·Hardness testing

·Tensile strength testing 

Thread accuracy can be inspected according to ISO 6g requirements where applicable. Inspection items are selected according to the applicable specification and agreed quality requirements.

FAQ

1) Can you identify a replacement bolt if I do not have the original drawing?

Yes. A detailed drawing is not always necessary to begin the specification review. A physical sample, photos, measurements, crusher model, or original part number can be provided for reference.

2) What dimensions are important when ordering a replacement bolt?

Thread diameter, thread pitch, thread length, overall length, and head dimensions are important reference points. The crusher model and installation position should also be considered.

3) Can you manufacture non-standard cone crusher bolts?

Yes. Non-standard dimensions and configurations can be manufactured according to confirmed technical requirements. Available references may include drawings, physical samples, photos, measurements, or other specification details.

4) What is the MOQ for cone crusher bolts?

Standard products can be ordered from 1 piece when available from stock. Customized non-standard parts typically have an MOQ of 30–50 pieces per batch, depending on process complexity and order requirements.

5) How is the lead time determined?

Lead time depends on the bolt configuration, material, order quantity, machining requirements, and production schedule. The delivery schedule is confirmed after the product and order requirements have been reviewed.
