1. A system for conducting subterranean operations, the system comprising:
a spinner assembly comprising:
an encoder; and
a spinner subassembly, the spinner subassembly comprising:
a spinner with an outer gripping surface, wherein the outer gripping surface is configured to engage a tubular; and
a drive gear coupled to the spinner via one or more other gears, with the drive gear configured to drive rotation of the spinner via engagement of teeth of the drive gear with the one or more other gears, and the encoder configured to count the teeth of the drive gear as the drive gear rotates, wherein the encoder detects an actual number of teeth that pass by the encoder, wherein the actual number of teeth indicates estimated revolutions of the tubular while the tubular is threaded into a second tubular via the spinner, and wherein an unacceptable wear status of the outer gripping surface is indicated when the estimated revolutions are greater than expected revolutions of the tubular.
