Constructed from high strength alloy steel, the ZHUOYUE cone crusher U-Bolts have a tensile strength of at least 850 MPa and hardness of 28-32 HRC after heat treatment according to the certified specification. All main dimensions and threads are done according to verified drawings or specified dimensions which make fastening of U-bolts and their alignment possible. OEM part numbers, prototypes and dimensions can be discussed for model-specific situations. We also prepare matching nuts and inspection reports as per your orders.
Product Introduction
Cone crusher U-bolts together with nuts are subject constantly to vibrations, loads that hit them suddenly, repeated tightening operations and clamping forces that are not the same at all time periods.
In case the material, heat treatment method, thread, or dimensions of the fastener are not in accordance with the required ones for the equipment, there may be loosening of the fastener or its components, changing of shape, deformation, damage to the thread, or breaking of the part.
The main issue for purchasing and service departments is not only the strength of the fastener but also whether the U-bolt fits the crusher model, original equipment manufacturer part number, mounting location, and necessary size of the part.
Our Solution
Fasteners for cone crushers and their nuts are produced by ZHUOYUE out of high-strength alloy steel, through a method of a whole-body forging process followed by a heat treatment process of quenching and tempering, all according to the approved technical specification sheet. The existing product standard specifies a tensile strength of ≥850 MPa and hardness level between 28 and 32 HRC, which set down clearly the mechanical property of a specified material to be met for that kind of fastening application.
How We Control Fastening Performance
Material selection & heat treatment: In order to provide strength and resistance at high loads, high-strength alloy steel is subjected to forging and appropriate heat treatment according to confirmed specification.
Mechanical_property_verification: Tensile strength and hardness are maintained in line with agreed technical specifications and can be confirmed by means of inspection records.
Dimensional Control:Critical dimensionsaremanufacturedaccordingtoapproveddrawingorconfirmedspecification.Adeviationof±0.02 mm may besetin certain cases where this is required technically.

Value to the Buyer
Fastening problems due to material properties of a wrong type or deviation of measurements can be avoided with this help.
Installation of bowl liners and other crusher parts as required through fasteners is assured with consistent clamping by the Buyer.
It prevents the premature replacement of components due to wear, deformation, thread damage, or fastener fracture.
Specifying material, mechanical-property, and dimensional requirements help ensure that repeat procurements meet the same standards.
Buyers can send the crusher model, OEM part number, drawing, sample, or key dimensions for technical review before production.

Cover Product Advantages:
1. Forged Construction for Repeated Loading
Forging and heat treatment processes are adopted during the production of U-bolts to achieve mechanical characteristics necessary for heavy-duty fastening applications. A specific tensile strength and hardness requirement set the quantitative indicators for material and process testing.
2. Stable Clamping Support
Getting the correct size and thread of the U-bolt helps hold your setup together for bowl liners and other identified parts of your crusher that may require some tightening with U-bolt. These are the main things they will be referring to at the end in order to check the drawings or the technical specification have already been approved.
3. Fitment according to the application
Manufacturing of U-bolts is possible according to the crusher model, the OEM part number, drawings, a sample, or confirmed dimensions. It is also a fastening configuration that corresponds to a specific mount area instead of a standard size U-bolt that would be the only option.
4. Repeat Procurement Consistency
With regards to subsequent orders, it is acceptable that the drawing (along with material specification, mechanical-property requirements and inspection criteria) approved for the first one is used as the reference for further production. This helps with keeping the product uniform across various batches.
5. Inspection-Based Quality Control
Material verification, mechanical-property inspection, dimensional inspection, thread inspection, and surface inspection can be carried out according to the verified quality requirements. When ordered, we will submit relevant inspection report.
Product Application:
We use U-bolts to lock the cone crusher in its position as a specified fastener part and for components such as bowl liners and other wearing parts that need a fastener part of U-bolt in the equipment design.
Some of the typical applications areas we cover are:
- Mining and ore crushing
- Quarrying and aggregate production
- Construction aggregate processing
- Industrial material crushing
- Heavy-duty crusher maintenance with a new one being fitted at the end
Please, before the manufacture, confirm the related crusher model, the location of fastening, size of U-bolt, thread specification if you would like non-standard U-bolts for the crusher model, the OEM part number, drawing, sample, or measured dimensions.
