Accuracy and Performance

High temperature is compatible. Heat stabilized components allow for operating temperatures to 500º F (260º C)
Journal diameter (JD) tolerance is +.0000, -.0007 inch (+0.00 mm, -0.02 mm).
Shoulder thickness (H) tolerance is ±.001 inch (±0.03 mm).
V height (VH) tolerance is ±.002 inch (±0.05 mm).
Eccentricity (EC) tolerance is ±.005 inch (±0.13 mm).
Nuts are manufactured to DIN standard 934 (18-8 stainless steel).
Washers are manufactured to DIN standard 125 (18-8 stainless steel).
See original guide wheel specifications for detailed data on wheels.
See load/life discussion in the technical reference section for sizing and selection information.
