AIGI 5505 Arrowhook Split Rotary Seal
The AIGI 5505 is the general-application member of the patented Arrowhook double-split rotary seal series, molded in polyurethane. Because the seal splits open, it installs around the shaft with no equipment disassembly, cutting seal-replacement time dramatically.
Product Benefits
- No machine teardown: Changing a conventional bearing seal usually means stripping the machine; the Arrowhook design removes that cost almost entirely.
- Duo-lock split closure: Two engineered splits positioned at the 55 and 5 o'clock points close with a ball-and-socket duo-lock.
- Double sealing security: The inner-and-outer ring structure provides double security with no leakage across either the ID or OD faces.
- Fraction of the downtime: A seal change takes a fraction of the usual downtime, with sealing integrity that does not depend on how carefully a one-piece seal was pressed in.
Where It's Used
- General-purpose model: The 5505 is the general-purpose model of the series, chosen for rotary bearing sealing.
- True-running shafts: It suits equipment whose shafts run true with low runout and at modest speeds.
- Quick-change default: It is the sensible default wherever quick, no-disassembly seal replacement is the priority.
Good to Know
- Polyurethane construction: This variant is molded in polyurethane and rated for a moderate temperature window and low shaft speeds.
- Series scales with duty: The 5505H covers faster shafts and higher temperatures, and the 5505HZ handles machines with much larger runout.
- Verify runout first: Check the shaft's runout before selecting, since the general model expects well-aligned equipment.
