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.

This place is great. They've got a lot more than just bearings, too. This is the place to go if you want good advice on installing a high-end, industrial-grade pneumatic set-up in your shop. And absolutely nothing but good things to say about their customer service, refund policy, etc. Highly recommended.

Top notch guys here. They're always helpful when I need an oddball seal or bearing, even if it's only a few dollars purchase. Thanks, Whisler!

Top Notch! I had a difficult project and the folks at Whisler Bearings in Denver were incredibly helpful and knowledgeable. I will definitely head there first again next time.
