PingduNickel retaining ring

Category:

PingduFastening ring

Product description

One-way memory ring for assembling piezoelectric accelerometer, which is a key component in ensuring accurate measurement within the accelerometer.


Provides stable clamping force within a temperature range of -50℃ to +250℃, assisting the sensor to operate stably in complex and harsh environments, reducing failures and extending the service life of the sensor.

Thermal Expansion Rings

 

These rings expand in diameter when heated, rather than contracting. The outer diameter expands by approximately 2.5%.
Expansion rings can be used for applications where contraction rings cannot be designed. Custom sizes are available.

 

Expansion Rings

These standard cylindrical pins expand in diameter by approximately 2.25% when heated.
They are commonly used as zero insertion force locating pins or as hole plugs in high-pressure or restricted-access applications.
