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.
Range[edit | edit source]
Industrial Duty | ||
---|---|---|
FEATURE | BENEFIT | |
“R” Series | Full width | More tolerant of static misalignment and accepts a more aggressive seal. |
Three-piece R-seal with fiber | Longer sealing integrity provided by outboard and inboard caps. | |
Eccentric locking collar | Self-tightens in application with no shaft damage. | |
“Y” Series | Full width | More tolerant of static misalignment and accepts a more aggressive seal. |
Three-piece R-seal with fiber | Longer sealing integrity resulting from outboard and inboard caps. | |
Set screw locking with Shaft Guard technology | Easy to install, well suited for reversing applications,and protects shaft from set screw damage. |
Standard Duty | ||
---|---|---|
FEATURE | BENEFIT | |
“V” Series | Narrow width | Ideal where space is limited. |
Model R-seal | Buna-N rubber contact. Shroud to protect seal and rabbet to prevent seal lip inversion. | |
Eccentric locking collar | Self-tightens in application with no shaft damage. | |
“S” Series | Narrow width | Ideal where space is limited. |
Three-piece seal | Buna-N rubber contact. Shroud to protect seal and inner cap to prevent seal lip inversion. | |
Set screw locking | Easy to install and ideal for reversing applications. |
Feature and Benefits[edit | edit source]
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. |
