Spring Loaded Mechanical Assembly With Mounting Plate U Bracket Ball Head Shaft

Product Specification

Spring Loaded Mechanical Assembly With Mounting Plate U Bracket Ball Head Shaft Brass Bushing precision metal parts

This spring-loaded mechanical assembly is a high-precision, compact metal component designed for integration into industrial equipment, automation systems, or mechanical devices requiring elastic connection, precise positioning, or trigger-based actuation.

Constructed from robust metal materials, the assembly consists of several tightly integrated parts engineered for performance, durability, and ease of mounting.

Component Breakdown

1. Base Plate
   A flat metal base featuring two mounting holes, allowing the component to be securely fixed to external structures or frames. The plate provides stable support for the entire mechanism.

2. U-Shaped Metal Bracket
   Mounted vertically on the base plate, the U-bracket acts as a support housing. One side of the bracket extends into a flat metal tab, which may serve as a structural reinforcement or connection point.

3. Central Shaft with Ball Head
   Passing through the center of the bracket is a smooth, cylindrical metal rod, whose upper end is topped with a polished metal ball head. This rounded tip can be used for precise contact, positioning, or as a trigger interface.

4. Brass Bushing (Golden Sleeve)
   Fitted around the shaft beneath the ball head is a gold-colored brass bushing, which provides low-friction guidance and enhances wear resistance.

5. Compression Spring
   A robust metal spring is compressed between the brass bushing and the base plate, giving the shaft vertical elasticity. The spring mechanism enables controlled retractability, restoring the shaft to its original position after displacement.

Functional Applications

This component is designed to serve multiple functions in mechanical systems:

• Elastic connection for movable parts
