Preliminary Investigation of Needle Bearings of 1 1/8-inch Pitch Diameter at Speeds to 17,000 Rpm

E. Fred Macks1949
Preliminary investigation of 1 1/8-inch-pitch-diameter of needle bearings was conducted over a range of shaft speeds of 2000 to 17,000 rpm, loads of 3.5 to 600 pounds per square inch, and oil flows of 0.5 to 25 pounds per square inch, and oil flows of 0.5 to 24 pounds per hour.
