TTHDFLSA THRUST TAPERED ROLLER BEARINGS B–8424–C

TYPE TTHDFLSA
• Same basic roller and raceway design as the TTHDFL, except
that the lower race is composed of two pieces whose faces are
spherically ground to permit self-alignment under conditions of
initial misalignment.
• TTHDFLSA bearings should not be used if dynamic misalignment
(changing under load) is expected.

Boyal Industrial Pte ltd.’s TTHDFLSA THRUST TAPERED ROLLER BEARINGS B–8424–C is designed for the rigors of daily use in applications where moderate and high speeds, high radial loads, elevated temperatures and debris are constant challenges. Designed with well-balanced cross sections, TTHDFLSA THRUST TAPERED ROLLER BEARINGS provide high-radial-load capacity within the bearing envelope.

The radial internal clearance (RIC) for the bearing assembly must be included when ordering either a) the complete assembly or b) with the inner-ring set. It is advisable to order the inner-ring set independent of the outer ring set when the final grind of the inner-ring O.D. is accomplished after mounting on the roll neck.

TTHDFLSA THRUST TAPERED ROLLER BEARINGS is four-row construction, having two single flanged outer races and rib rings for roller spacing. This allows for complete disassembly for inspection. The style is usually preferred in bearings above 400 mm bore.
Both brass and pin-type cages are available in this bearing style. Most inners are two-piece assemblies.
