Automotive, aviation and high-performance engine bearings company King Engine Bearings, Cedar Grove, N.J., has released the video of a technical seminar conducted at two race industry trade shows in December 2011.
Ron Sledge, King’s performance and technical manager, presented “Race Engine Bearing Lubrication, Clearances & Tolerances” to standing-room-only crowds at two industry trade shows last winter, according to a press release. The hour-long presentation is now available to view, free-of-charge here.
Sledge shared his knowledge of engine bearings and race engine technology accumulated over his 30-plus-year industry career.
He told the audience of race engine builders, “My goal is to help you produce engines with the most horsepower, torque, and durability,” the release noted.
The seminar looks at bearing performance considerations for racing applications, including oil viscosity, oil type (synthetic vs. mineral), oil pressure and temperature, proper bearing clearances, proper surfaces finishes and bearing assembly tolerances.
Sledge also talks about the importance of wall thickness.
“Inconsistent shell-to-shell bearing wall thickness can have a negative impact on clearances between the bearing and the journal on main and connecting rod bearings,” he explained.
