How do I prevent hand pain and calluses when training on the bar?

Some callus build-up is normal and actually helpful. Calluses protect your hands over time. The goal is not to avoid them entirely but to manage them so they do not tear.

The most important thing you can do is file your calluses regularly. When they build up into hard ridges, they are much more likely to rip during a session. A pumice stone or callus file used a couple of times a week keeps them flat and smooth. Do this when your hands are dry, not after a shower.

Grip position matters too. A common mistake is gripping the bar too deep in the palm. The bar should sit at the base of your fingers, not across the middle of your palm. This reduces the folding of skin that causes calluses to form and tear.

For acute hand pain or sensitivity, chalk helps significantly. It reduces the friction that causes skin to drag and bunch. Liquid chalk is easier to use at home and does not create the mess that loose chalk does. A thin layer is enough.

Gloves are a personal choice. They reduce skin friction and can help when your hands are still adapting, but they also reduce your bar feel and grip strength development over time. Most experienced calisthenics athletes train without them. If you use gloves, treat them as a temporary solution while your hands toughen up rather than a permanent fix.
