  Constraints on the linear growth rate, $f\sigma_8$, using small scale
redshift space distortion measurements have a significant statistical advantage
over those made on large scales. However, these measurements need to carefully
disentangle the linear and non-linear information when interpreting redshift
space distortions in terms of $f\sigma_8$. It is particularly important to do
this given that some previous measurements found a significant deviation from
the expectation based on the $\Lambda$CDM model constrained by Planck CMB data.
We construct a new emulator-based model for small scale galaxy clustering with
scaling parameters for both the linear and non-linear velocities of galaxies,
allowing us to isolate the linear growth rate. We train the emulator using
simulations from the AbacusCosmos suite, and apply it to data from the extended
Baryon Oscillation Spectroscopic Survey (eBOSS) luminous red galaxy sample. We
obtain a value of $f\sigma_8(z=0.737)=0.368\pm0.041$, in 2.3-$\sigma$ tension
with the Planck 2018 $\Lambda$CDM expectation, and find less dependence on the
minimum measurement scale than previous analyses.
