Threaded Stud/Bolt: Length Range 20mm to 300mm

Component Specifications

Definition

A threaded fastener component used in vibration isolators to securely mount equipment while allowing controlled movement and damping of vibrations. It typically features precision threads, specific length and diameter specifications, and may include features like shoulder sections or special coatings for enhanced performance in vibration damping applications.

Working Principle

Provides rigid mechanical connection between vibrating equipment and vibration isolator base while allowing the isolator to absorb and dissipate vibrational energy through controlled deformation or damping materials. The threaded design ensures secure fastening with proper preload to maintain connection integrity under dynamic loads.

Materials

Typically carbon steel (Grade 5, Grade 8), alloy steel, stainless steel (A2/A4), or specialized vibration-damping alloys. May include coatings like zinc plating, hot-dip galvanizing, or phosphate coatings for corrosion resistance.

Frequently Asked Questions

What is the difference between a threaded stud and a bolt in vibration isolators?

A threaded stud typically has threads on both ends and requires nuts for fastening, allowing for precise adjustment of mounting height. A bolt has a head on one end and threads on the other, providing quicker installation but less adjustability. Both serve similar functions in vibration isolator applications.

How do I select the correct threaded stud for my vibration isolator?

Consider the equipment weight, vibration frequency, required preload, environmental conditions (corrosion, temperature), and compatibility with the isolator design. Consult manufacturer specifications for diameter, length, material, and strength grade requirements.

Can standard bolts be used instead of specialized vibration isolator fasteners?

While standard bolts may work in some applications, specialized vibration isolator fasteners often include features like controlled elasticity, specific coatings, or design elements that enhance vibration damping and prevent loosening under dynamic loads.
