• You Need It. We Have It. Try Whisler.


  • Drip. Drip. Drip. One of the most annoying sounds you can hear. Hopefully, the next sound you hear is not grinding gears, squealing bearings or the sound of someone slipping in a puddle of oil. In our business successful sealing means longer bearing, gearing and equipment life.

    At Whisler Bearings & Drives we stock over 3000 sizes of oil seals in inch & metric sizes, various materials and lip configurations.   That’s over 7000 seals on our shelves ranging in size from ¼” to 10” shaft diameter.   In addition, we stock over 150 sizes of Speedi-Sleeves used for repairing grooved and leaking shaft surfaces.   Very rarely will you walk into Whisler Bearing needing a seal and end up empty-handed.
