The bottom of the Pinball Life perfectplay silicone leg leveler casters are slick.
These are made out of rubber, and grip the floor better:

I buy them by the hundred.
I usually don't recommend suzo products, so if you get on the suzohapp webpage and try to buy ANYTHING ELSE for a pinball you may end up in tears. (Seriously, don't buy their leg levelers, their flipper cranks, the list goes on and on... extremely poor quality!)
When you use the leg leveler cups from suzohapp, you won't be scooting the front of the pinball when you nudge.
As for scooting the pinball out for service, I try to make sure that the customers VERY expensive wood flooring is never damaged, so I like the Happ leg leveler cups. They will scoot on wood, but only with care. I think the pinball life silicon version might suit you better if you are constantly pulling your pinball out for service.
