Since 1998 we have been focusing our activities in the oilfield and mining trades through out the world. We wanted the most demanding industry to prove our bearings. We were very successful, with no returns and no premature failures. Just like all the major bearing companies, we have factories all over the world producing bearings for us, including England, USA, China, India, Romania and the Czech Republic. We market them exclusively through Heller Enterprises under our brand “DIT.” Our bearings are held to the strictest of quality standards. Standard delivery for items that are not in stock is 2-7 weeks depending on the item.
