¦If applied over 100Ž conditions, clearance should be designed by adding below heat expansion @amount to the inner diameter tolerance at room temperature. @Heat expansion amount  heat expansion co-efficient of shaft (ƒ¿) ~ shaft diameter (d) ~ (ambience temperature | room temperature) @ƒ¿ of soft steel : 1.12 ~ 10|5/Ž ¦If applied above 100Ž conditions, interference of the outer diameter may be reduced due to stress relaxation. @Detent screwing is recommended. ¦For fitting design with temperature over 200Ž, please inquire an OILES representative. iUnit : mmj Up to 10 Exceeding 10 & up to 18 Exceeding 18 & up to 30 Exceeding 30 & up to 50 Exceeding 50 & up to 80 Exceeding 80 & up to 120 Exceeding120 & up to 180 Exceeding180 & up to 250 Exceeding250 & up to 315 Exceeding315 & up to 400 Exceeding400 & up to 500 Up to 10 Exceeding 10 & up to 18 Exceeding 10 & up to 18 Exceeding 18 & up to 30 Exceeding 18 & up to 30 Exceeding 30 & up to 50 Exceeding 30 & up to 50 Exceeding 50 & up to 80 Exceeding 50 & up to 80 Exceeding 80 & up to 120 Exceeding 80 & up to 120 Exceeding120 & up to 180 Exceeding120 & up to 180 Exceeding180 & up to 250 Exceeding180 & up to 250 Exceeding250 & up to 315 Exceeding250 & up to 315 Exceeding315 & up to 400 Exceeding315 & up to 400 Exceeding400 & up to 500 Exceeding400 & up to 500 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0.015 0.015 0.018 0.018 0.021 0.021 0.025 0.025 0.030 0.030 0.035 0.035 0.040 0.040 0.046 0.046 0.052 0.052 0.057 0.057 0.063 0.072 0.075 0.110 0.114 0.155 0.160 0.216 0.223 0.300 0.308 0.396 0.406 0.510 0.522 0.636 0.649 0.728 0.740 0.818 0.832 0.950 0.050 0.053 0.083 0.087 0.122 0.127 0.177 0.184 0.254 0.262 0.342 0.352 0.447 0.459 0.564 0.577 0.647 0.659 0.729 0.743 0.853 0.057 0.057 0.092 0.092 0.133 0.133 0.189 0.189 0.266 0.266 0.354 0.354 0.458 0.458 0.572 0.572 0.651 0.651 0.729 0.729 0.847 0.035 0.035 0.065 0.065 0.100 0.100 0.150 0.150 0.220 0.220 0.300 0.300 0.395 0.395 0.500 0.500 0.570 0.570 0.640 0.640 0.750 0.072 0.072 0.110 0.110 0.154 0.154 0.214 0.214 0.296 0.296 0.389 0.389 0.498 0.498 0.618 0.618 0.703 0.703 0.786 0.786 0.910 0.035 0.035 0.065 0.065 0.100 0.100 0.150 0.150 0.220 0.220 0.300 0.300 0.395 0.395 0.500 0.500 0.570 0.570 0.640 0.640 0.750 0.015 0.018 0.018 0.021 0.021 0.025 0.025 0.030 0.030 0.035 0.035 0.040 0.040 0.046 0.046 0.052 0.052 0.057 0.057 0.063 0.063 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0.034 0.041 0.041 0.049 0.049 0.059 0.059 0.073 0.073 0.089 0.089 0.108 0.108 0.130 0.130 0.150 0.150 0.171 0.171 0.195 0.195 0.019 0.023 0.023 0.028 0.028 0.034 0.034 0.041 0.041 0.051 0.051 0.063 0.063 0.077 0.077 0.094 0.094 0.108 0.108 0.126 0.126 0.034 0.041 0.041 0.049 0.049 0.059 0.059 0.073 0.073 0.089 0.089 0.108 0.108 0.130 0.130 0.150 0.150 0.171 0.171 0.195 0.195 0.004 0.005 0.005 0.007 0.007 0.009 0.009 0.011 0.011 0.016 0.016 0.023 0.023 0.031 0.031 0.042 0.042 0.051 0.051 0.063 0.063 I.D.
