King manufactures its automotive, aviation and high performance engine bearings to “Bull’s Eye Tolerance,” which is the company’s commitment to ultra-precise control of the critical wall thickness tolerance.

“We are excited to celebrate our 50th anniversary and the distinction of manufacturing our bearings to this unique ‘Bull’s Eye’ standard,” said Michael James, vice president of export sales and marketing, King Engine Bearings. “King recognized a long time ago that engine builders wanted and needed engine bearings with better tolerance control, greater reliability and superior longevity.”

James says inconsistent shell-to-shell wall thickness has an adverse impact on an engine’s bearing-to-crank-journal clearances. Typically this has resulted in engine builders having to compensate for these inconsistencies by pre-sorting and then select fitting differently graded shells – a very time consuming and costly process. “At King, our Bull’s Eye Tolerance commitment has removed the inconsistency factor. It’s a superior standard for people who demand superior results,” explained James.

King utilizes statistical analysis, state-of-the-art manufacturing, and in-line process control to hold rod and main bearing wall thickness tolerances to an exceptionally precise+0.0001″. This far outperforms other manufacturers whose wall thickness at the crown can vary by up to +0.00025″.

Benjamin Baloga, plant engineering manager, Tomadur Engine Co., City of Industry, Calif., says Tomadur has used King Engine Bearings for over 10 years. “King has proven that they are able to hit that Bull’s Eye number every time,” he says.

Baloga says another company from which they bought bearings in the past was quite inconsistent and forced internal measurements of every rod bearing they received. “We are very demanding at Tomadur,” explained Baloga, “and King has earned our confidence. King saves us a lot of time, aggravation and money because they’re as picky as we are.”

Through its Bull’s Eye Tolerance standard, James says King is able to provide a level of product consistency that is unmatched by any competitor.

“Because of our bearing consistency, engine builders can more easily achieve their targeted rod and main clearances. This makes their shop more efficient and their engines more dependable,” he explains. “King is proud to bring added-value to its customers through the Bull’s Eye tolerance advantage.”
