Applications involving loads approaching this rating or the tabulated working load, whichever is the smaller, should be referred to the Torrington Engineering Sales Office before a final selection is made. Load Ratings are based on a minimum raceway hardness of 58 HRC or equivalent. Load ratings are given in pounds-force: 1 lbf = 0.454kgf = 4.448N Required Basic Dynamic Load Rating (Cr) = Applied Load • SF • LF • HF (see page E75). |
