Category: Needle Roller / Axial Cylindrical Roller Bearing
Dimensions: 30x80x43mm

Overview

INA ZARN3080-TV-A Needle Roller / Axial Cylindrical Roller Bearing combines radial needle rollers with an axial cylindrical roller thrust section for high axial load capacity. It suits gearboxes, screw supports, and machine tools requiring high axial rigidity in restricted space.

The needle roller section supports radial load, while the axial cylindrical roller section supports high thrust load. Precision variants such as ZARF use flange and bolt features for screw-drive positioning.

Key features

Supports radial and high axial loads together
High axial rigidity
Compact combined bearing structure
Applicable to precision screw supports

Typical applications

Industrial gearboxes
Ball screw and lead screw supports
Machine tool feed axes
Compact high-load drives

Selection guidance

Review axial load, rigidity requirement, washer/flange configuration, lubrication, precision, and available mounting space.
