Floating Seals and Bearings for Undercarriage Components
Share
A floating seal is the reason an oil-filled roller lasts a service interval instead of a season — two lapped metal rings held together by an O-ring, sealing a rotating joint that nothing else can seal. This page covers how duo-cone seals work, why they fail, and what to specify when ordering.
Choosing and matching
Start here when you are specifying a part. The questions these articles answer decide the part number before price enters the conversation.
Materials, hardening and manufacturing
Forging, heat treatment and hardness decide how a part behaves under load. These articles explain what the specifications actually buy.
Seals, lubrication and internal parts
The parts inside a component that decide its life — seals, bearings and lubrication — and why they fail before the shell does.
