Since introducing the wide inner ring bearing design in the early 1900s, the Fafnir brand has been a leading name in ball bearing housed units. Today, the Timken® Fafnir® names can be found on a wide array of housed units.Buying Fafnir means more than just a bearing. The product inside each box represents decades of experience. The lessons learned and engineering applied result in reliable performance.

Feature and Benefits
| FEATURE
|
BENEFIT
|
| Grease fitting offset
|
Minimized risk of accidental and side impact, while maintaining accessibility for single-point lubricators.
|
| Fafnir curl
|
Mechanical attachment of seal is secure, resisting “pop-out” during re-lube and inhibiting spinning of the seal in the outer ring seal groove.
|
| Grade 10 balls
|
Quiet and smoother-running bearings resulting from higher specification steel and improved roundness.
|
| Buna-N seal material
|
Buna-N rubber has cotton fiber, embedded to wick oil, which enhances lubrication and improves sealing integrity.
|
| 6/6 nylon heat stabilized retainer
|
Excellent misalignment capability. Resists size changes and moisture trapping.Non-corrosive and self-lubricating, as well as resistant to abrasion, wear and most solvents.
|
| Super-finished raceways
|
Even surfaces reduce friction, leading to cooler, quieter running and longer life.
|
| Hardened and ground seal land
|
Seal protected from inner ring abrasion, resulting in less wear (longer life) and prolonged seal integrity.
|
| Powder coat finish
|
Chipping, scratching and subsequent exposure to parent metal is reduced, helping to prevent corrosion.
|
| Special quality steel
|
Fewer carbides, inclusions and voids result in reduced risk of stress risers that can cause premature fatigue.
|
| Double-filtered polyurea grease
|
Particles that can cause noise in application are removed. Improved lubrication cleanliness also leads to superior performance at higher speeds.
|
| Housing tolerances
|
Better grease purge throughout the bearing due to reduced risk of grease purge at outer diameter.
