liner shell vent.

[teylora]

Помогите, пожалуйста, с выражением liner shell:

1. Set the bottom liner shells into the bottom housing sections. Prelubricate the shells with a film of oil.
2. Lower the fan shaft into the liner shells and align the rotating element so that the wheel and shaft does not strike any portion of the housing or inlet fixture. A slight clearance must be present between each side of the liner and the shaft. This clearance should be equal on both sides, and uniform along the length of the liner.

Спасибо.
