Tapered Roller Bearings FAG 32317

The FAG 32317 tapered roller bearing is designed for combined radial and axial loads, with main dimensions of 85 × 180 × 63.5 mm.

The 32317 tapered roller bearing is designed as a single-row rolling bearing for demanding industrial applications. Thanks to the tapered arrangement of the rolling elements, this design efficiently transmits simultaneously occurring radial and axial loads via line contact. The manufacturer, FAG, supplies this standard version as a complete bearing, comprising an inner ring with a roller cage and cage, as well as a separate outer ring. As the inner and outer rings can be fitted separately, this simplifies their individual installation in housings and onto shafts.

In which configurations is the 32317 tapered roller bearing used?

This tapered roller bearing is used in mechanical designs where radial forces must be supported together with axial thrusts acting from one side. As a single tapered roller bearing, by design, can only support axial forces in one direction, it is usually fitted in pairs in an X or O arrangement with a mirror-image counterpart bearing. This paired arrangement allows for the precise adjustment of operating clearance or a defined preload to ensure stable shaft mountings in general mechanical engineering.

What is the function of the sheet steel cage in the 32317 tapered roller bearing?

The integrated sheet steel cage guides the tapered rolling elements along the hardened raceways and prevents direct contact between the rollers. This reduces internal friction and promotes the flow of lubricant within the bearing during operation. The design is rated for an operating temperature range of -30 to +120 degrees. Manufactured to tolerance class P0 or ABEC 1, the roller bearing fits precisely into standardised mounting arrangements.
