stopper bolts / hexagon socket at head / regular thread / hard rubber protective head / stainless steel / A57

Specifications/Overview

■Material with excellent shock absorption
·Low elastic rubber
It is used as cushioning material for pallet damper, conveyor machine, precision instrument, etc., because of its good elongation and shock absorption.
Also it is used as vibration absorption materials of various precision instruments because of its excellent vibration absorption.

■Impact resilience variation by temperature of low elastic rubber

■Shock absorption of low elastic rubber

■Drop comparison of rubber ball and low elastic rubber ball

Description/Basics

MISUMI stopper bolts are generally used as damped and undamped stops for components and applications in mechanical engineering.
Undamped stopper bolts are protected against premature wear with hardened tips or heads. However, undamped stopper bolts may damage component surfaces. To protect the components to be stopped, a damped stopper bolt may protect the surface against damage with a rubber or plastic baffle head. In addition, MISUMI offers a stopper bolt with rubber or hard rubber in different Shore hardnesses, which can dampen the impact and reduce vibrations.
In addition to the standard threads, MISUMI also offers the stopper bolts with fine threads. The stopper bolts with fine threads enable finer adjustments compared to standard threads.
MISUMI offers Threaded Stopper Blocks as suitable and robust fastening for the assembly of the stopper bolts.

The stopper bolt can serve as a stop protection for workpiece carriers in order to protect them from damage. A stopper bolt with rubber can also reduce vibrations and oscillations to protect the goods to be transported. Often, stopper bolts are combined with industrial adjustable shock absorbers as end position damping to protect the damper from a hard end stop.
The stopper boltcan also be used alternatively in clamp.
