摘要：
A meter roller for an agricultural metering system includes a spindle having a driven shaft, a first ring, and a second ring. The first ring and the second ring are rigidly coupled to the driven shaft, and the driven shaft is configured to engage a drive shaft to facilitate rotation of the spindle. The meter roller also includes a sealing ring longitudinally disposed between the first ring and the second ring. An outer diameter of the sealing ring is less than or equal to an outer diameter of the first ring and an outer diameter of the second ring, and the sealing ring is formed from a material having sufficient resilience to enable the sealing ring to stretch to facilitate disposition of the sealing ring between the first ring and the second ring.
