Key words: turbodrill, shaft seal, leaks, rubber-steel thrust bearing, hydraulic treatment of drill bit.
The paper provides findings of experimental investigations into performance of rubber-steel thrust bearing with recessed rubber. It is shown how this rubber-steel thrust bearing is better than the standard rubber-coated nipple and helps to increase penetration rate (1,8 – 3 times).
