We investigate the contact types of a regular surface in the Euclidean 3-space ℝ3 with right circular cylinders. We present the conditions for existence of cylinders with A1, A2, A3, A4, A5, D4, and D5 contacts with a given surface. We also investigate the kernel field of A≥3-contact cylinders on the surface. This is defined by a cubic binary differential equation and we classify singularity types of its flow in the generic context.
