Natural rubber rings suppress noise

A new series of natural rubber rings and bushings are designed for noise suppression in typewriters, printers, copiers and other precision office or lab equipment.

A new series of 38 natural rubber rings and bushings introduced by Stock Drive Products are designed for noise suppression in typewriters, printers, copiers and other precision office or lab equipment.

Additionally, they isolate striker bars and platens as well as printhead guide rails in high-speed printers; inertial dampers to lower access time for stepper motor applications plus their general use in protecting sensitive instrumentation from unpredictable vibration and shock.

Identified as the A10R 4-Finger-Flex Series, they provide protection for loads ranging from 1.8 to 159kg and exhibit various natural frequencies depending on the size and durometer hardness of the isolator.

Hardness durometers range from 30 to 60.

Five basic sizes are stocked.

One has a 0.40625in diameter with a 0.25in bore for loads up to 5.4kg.

For loads up to 11.3kg, there are 1.171875in diameter units with a 0.375in bore.

Prices start at just $2.72 each in single unit quantities.
