STOCKHOLM, July 18 (Reuters) - Sweden's SKF, the world's biggest maker of industrial bearings, reported adjusted second-quarter earnings in line with market expectations on Thursday and said it expected relatively unchanged like-for-like sales in the third quarter.

The company reported adjusted operating earnings of 3.32 billion crowns ($315 million) compared to 3.61 billion a year earlier to all but match a mean forecast 3.33 billion, according to a LSEG compilation of analyst estimates.

The engineering group, whose bearings are sold into a huge range of products across many industries, said the current subdued market demand, combined with its footprint regionalisation moves, could have short-term impact on its cost efficiency in the second half of the year.
