Bearing N-3311-A

TYPE TTHDFL
• Consists of one thrust tapered race, one flat race, rollers and cage.
• Most sizes utilize pin-type cages with hardened pins through the center of the rollers,
allowing closer roller spacing to maximize load capacity.
• Smaller sizes have brass cages designed for unidirectional retention of rollers.
• Combines the outstanding features of thrust tapered and cylindrical roller bearings to
offer the highest possible load capacity of any thrust bearing of its size.
• Originally developed for screwdown applications in metal rolling mills where high
axial loads are common.
