What wood species? Kiln dried? How big are the blanks? How big are the finished pieces?

I’m not a turning expert, but some possibilities occur to me … Some species of wood are more prone to checking than others. Turning away a lot of material can releave stresses in the wood, basically removing parts that were holding it together. Also, if the wood has an inconsistant moisture content, removing the outer layers could suddenly accelerate the drying of the inner layers.

I’ve heard that latex paint on the endgrain can help prevent splitting during the drying process, but I don’t know if it would help with checking.

To add to what Peter said- read somewhere that if you are turning spindles (or anything similar) from a log/branch you should try to avoid having the center growth rings centered in the ends of the spindle.

Again, I’m not an expert on turning, but I’m going with the accelerated drying of the newly exposed wood theory. You could try coating the whole spindle with something (maybe shellac?) to slow the drying process. Or you could turn it a little oversized, let it dry really well, then turn it down to your finished size.
