PowerTorq 1000-6-0187 SOR8944

Inch Standard Performance Ball Spline Assembly, 1" Nominal Size, 3/16" Nominal Ball Diameter, 6 Active Circuits

The PowerTorq™ Ball Spline assembly uses rolling elements to carry a load similar to an anti-friction (ball) bearing. These elements do not wear when properly lubricated during normal use. The closed path that the bearing balls follow through the outer race is referred to as a circuit. The number of potential circuits varies with the diameter of the spline shaft. When a circuit is loaded with bearing balls, it is referred to as an "active circuit".

PowerTorq™ inner races are made of high quality 4150 alloy steel, induction hardened to Rc 56-60. PowerTorq™ outer races are made of hardened steel with ball tracks heat treated to Rc 56-60. PowerTorq™ ball spline inner and outer races are protected with a black oxide finish.

PowerTorq™ Ball Splines are straight within .010 in/ft when shipped from the factory, and do not exceed .030 inch in any 6 foot section. Twist is limited to .015 in/ft at the ball circle diameter.
