SKF LOR labyrinth rings are part of the PosiTrac sealing system for bearing housings. An O-ring is built into the ring bore. The ring seals the housing around the shaft.
The full LOR code is the key to identifying the correct ring. The digits that follow LOR cannot be used alone to determine dimensions or compatibility. Always keep the complete part code and note the housing designation where the ring is installed before ordering a replacement.
Do not confuse a labyrinth ring with a blind cover or a bearing axial locating ring. These items may appear together as housing accessories, but they serve different purposes and are not interchangeable.
To request a quote, provide the LOR code, the quantity, and the housing identification. If the marking is unreadable, include photos of the assembly and any measurements you can take. MR reviews this information before suggesting a reference. Never assume equivalence with a seal from another series or brand based on appearance alone.
