Perfect fit for my lathe

Ordered the 6307Z for a repair job on an old lathe motor. The dimensions were spot on and it runs very smoothly. No excessive noise or vibration.

Good value for the price

Quality seems decent for the cost. It was slightly noisy during the break-in period but settled down after a few hours of operation.
