Fafnir

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

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

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.
