Reduced Noise Significantly
My lathe runs much smoother now. The elastic spider absorbs shocks well. Great replacement for the worn-out original part.

Excellent Precision for CNC
Used this for my CNC router spindle retrofit. The fit was perfect on both the motor and lead screw shafts. Vibration is almost non-existent now.

Good Value for Money
Works as expected for the price point. Comparable to more expensive brands I have used in the past. Fast shipping too.
