What is a Dust seal?

A dust seal prevents dust from entering from the outside and protects packings and bearings. As the name "dust seal" suggests, "dust = dirt, dust, and dust" is "sealed, sealed, and prevented from entering". Also known as a "packing". By changing the packing standard and combination according to the application, the cylinder can be protected and can be used without problems from low temperature (-30°C) to high temperature (80°C). The dust seal is the outermost part of the device and is used to protect the inside, so it needs to be replaced periodically.
