Tapered roller thrust bearing TTHDFL series

TAPERED ROLLER THRUST BEARINGS

Overview:
Vafem thrust bearings are built to handle high thrust loads and heavy shock. The distinctive on-apex design characteristic of tapered roller thrust bearings ensures true rolling motion, which reduces roller sliding and provides a smoother, cooler-running bearing than other thrust types. Available in a wide range of sizes and design styles, these bearings fi t many types of machinery in the industrial and automotive markets.

• Bore Sizes:

16.1 mm - 1550.0 mm (0.6337 in. - 61.0236 in.)

• Industries:

Aggregate, rubber and plastics, metals, oil, gas and power generation.

• Applications:

Cone crushers, crane hooks, oil well swivels, top drives, extruders, pulverizer drives, rolling mills, machine tool spindles and tables, drilling rig hydraulic heads, gear boxes and pre-heater fans.

• Benefits:

High performance and application flexibility versus other non-tapered bearing types. Large range of product offerings.

VAFEM tapered roller thrust bearings include conical rollers for true rolling motion. These bearings are engineered so that the rollers and raceway converge at a common apex point, which is on the center line of the bearing. Seating force between the rib and roller helps provide positive roller guidance.
VAFEM manufactures several types of heavy-duty tapered roller thrust bearings: standard
(TTHD), V-flat (TTHDFL) and self-aligning V-flat (TTVS). Timken also offers TTSP and TTC, lightduty thrust bearings designed for oscillating applications.

TTHDFL

The TTHDFL combines the outstanding features of tapered and cylindrical roller bearings, offering  the highest possible capacity of any thrust bearing of its size. The V-flflat design includes one  flflat ring and one ring having a tapered raceway matching the rollers. These bearings maximize  dynamic and static capacity within a given envelope. The design was originally developed for  screwdown applications in metal rolling mills. They also have been highly successful in heavily  loaded extruders, cone crushers, top drives and other applications where a wide range of  operating conditions are found. Most sizes utilize pin-type cages with hardened pins through  the center of the rollers, allowing closer spacing of the rollers to maximize capacity. Smaller  sizes have brass cages designed for unidirectional retention of rollers.
