Customized Seal Load/Friction in a Torque Sensitive Rotary Union
Rotary Unions are mechanical devices meant to allow the transfer of liquid or gas media from a stationary input to an output that is rotating. Rotary Unions are found in industries across the board, from compact units in hi-tech robotics to large industrial hydraulic units for construction equipment.
A classic example of where a rotary union is found would be in large hydraulic excavators or backhoes. The union permits

PTFE Resins Commonly Used in Seals
In this article, we’ll look at the fillers employed in PTFE resins.
In its virgin form, PTFE resin isn’t the best sealing material for dynamic shaft applications. Therefore, different fillers are added to achieve the desired results. The most common fillers are fiberglass, graphite, carbon, coke flour and molybdenum, although any filler can be added to virgin PTFE resin as long as the material can withstand maximum sintering temperature of 710-730 degrees

CNC Machining Seals with a Haas Automation Machine
CNC machining, which stands for Computer Numerical Control, is a manufacturing process in which pre-programmed computer software dictates the movement of tools and machinery.
The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers.
But in our case, Gallagher is utilizing this process to cut both custom and standard seal profiles for our customers.

Seals are small components that have a big function. At their most essential purpose, they keep fluid in and debris out. Failure to do this can lead to costly machine destruction, and even endanger the lives of people working around these machines. Preventing seal failure is very important on many different levels.
What Seals Are Up Against
Many factors can cause a seal failure. Being aware of these factors will help you in preventing an avoidable failure. Seals are under constant pressure

A combination of crimped can seals will handle a variety of applications when a rubber lip seal is not your solution.
Rotary seals are often secured in sealing hardware by crimping the sealing element in a metal can. One of the most common rotary seals is a molded rubber lip seal in a can.
While not crimped, the can retains the sealing element, and stops the seal from rotating in the gland. Rotary
