ZIBOO KOYO 32911JR Tapered Roller Bearings

The ZIBOO KOYO 32911JR is a tapered roller bearing designed for applications requiring combined radial and axial load support. It suits technicians and engineers who need a precise 55x80x17mm component for maintenance or assembly tasks. The red finish aids visual identification in a tool kit or parts bin.

Integration into mechanical assemblies

This bearing fits housings and shafts machined to the 55mm inner and 80mm outer diameters with a 17mm width. It replaces worn units in gearboxes, differentials or wheel hubs without requiring special tooling beyond standard bearing pullers and presses. The single pack supplies one complete unit ready for installation.

Behaviour under sustained load

The tapered roller geometry distributes contact stress across the raceways during continuous operation, reducing localised wear compared with ball types under similar combined loads. Proper lubrication and preload adjustment maintain running accuracy over extended duty cycles. The component is supplied new with a three-year parts and one-year labour coverage period.

Questions about this item

What is the maximum axial load the 55x80x17mm tapered roller bearing can sustain continuously?

The 32911JR bearing handles combined radial and axial loads; the exact axial limit depends on the applied radial load and lubrication conditions in your application.

How much heat does the KOYO 32911JR generate during all-day operation?

Heat rise is determined by speed, load, lubrication type and mounting fit; with correct grease fill and alignment the bearing runs at a stable temperature for continuous duty.

Which shaft and housing tolerances must I already have for the 55x80x17mm bearing to seat correctly?

The bearing requires a 55mm shaft and 80mm housing machined to the standard fits recommended for tapered roller bearings in your equipment manual.
