Bolts and brackets

I. Role of the bolt: stabilize the connection and prevent loosening  

Bolts are the core connections between industrial casters and equipment, and their functions include:  

● Ensure that the casters are tightly fixed to the equipment to avoid displacement due to vibration or impact  

● Withstand dynamic loads and remain stable when moving or steering  

● Prevent accidental falling off and avoid equipment losing control or tipping  

2. Common bolt problems and solutions  

● Loosening problem: Long-term vibration or load changes may cause the bolts to become loose. Lock nuts, thread glue or spring washers can be used to enhance fixation.& nbsp; 

● Corrosion problems: Moisture or chemical environment can easily cause bolts to rust. It is recommended to use stainless steel or galvanized bolts to improve corrosion resistance.& nbsp; 

● Insufficient strength: Overloading or impact may cause the bolt to break, so high-strength bolts (such as grade 8.8 or higher) should be selected to adapt to heavy applications. nbsp; 

III. Role of the bracket: support the load and prevent deformation  

The bracket (also known as the caster frame) is the load-bearing structure of the caster, which directly affects the stability and service life of the caster. Its main functions include:  

● Equally distribute the load to prevent deformation caused by excessive local stress  

● Provide steering or fixed support to ensure flexible movement or stable locking of casters  

● Resist impact and vibration and extend the overall life of casters  

4. Common stent problems and solutions

● Deformation problems: Overloading or frequent impacts may cause the bracket to bend. Thickening steel plates or forging brackets should be chosen to improve strength.& nbsp; 

● Risk of fracture: Poor-quality materials or welding defects may easily lead to cracking of the stent. It is recommended to use an integrated molded or heat-treated stent.& nbsp; 

● Corrosion problems: Moisture or chemical environments will accelerate the corrosion of brackets, so stainless steel or galvanized brackets are ideal.& nbsp; 

5. How to choose the right bolts and brackets? nbsp; 

1. Selection according to load: Light equipment can use ordinary carbon steel bolts and stamped brackets, heavy equipment requires high-strength bolts and forged brackets.& nbsp; 

2. Consider the use environment: Stainless steel or rust-proof materials should be used in humid or corrosive environments.& nbsp; 

3. Regular inspection and maintenance: Check the fastening degree of bolts every month, observe whether the bracket has cracks or deformation, and replace damaged parts in a timely manner.& nbsp; 

Although the bolts and brackets are small, they are the key to the safe operation of industrial casters. For casters selection applications, it is necessary to select appropriate bolt and bracket materials and specifications to maximize the stability and durability of industrial casters.
