Screw-down bearings (Rolling Mill Bearing)

Update date: 2020-10-28 18:27　 Attention: | Inquiry entry: sales@fv-bearing.com 　

FV offers two types of screw down bearings – types TTHDSV and TTHDSX. Both types consist of a full roller complement design without a conventional bore. Screw down tapered thrust bearings offer the highest capacity of the v-flat bearing types, but at a reduced speed capability.

Size ranges: 35 mm to 2940 mm (13.75 in. to 115.75 in.)

Design Attributes:

While these bearings do not have conventional bores, they are provided with center inserts for attachment and lifting purposes.

TTSV and TTSX type bearings achieve true rolling motion between the tapered rollers and both raceways, with no skidding or sliding at any point on the rolling surfaces.

The flat raceway permits radial displacement without affecting the operation of the bearing.

Applications: We engineered screw down bearings for use in applications that experience a wide range of operating conditions, including: Heavily-loaded extruders and Cone crushers
