  • Tapered-bore, antifriction bearings are mounted either on adapter sleeves or on tapered shaft seats.
  • In cases where tapered bore bearings are mounted directly on the shaft, the shaft must conform to the tapered bore of the bearing to assure proper fit. If a proper fit is not achieved, the results could be:
    • Turning of the bearing inner race on the shaft.
    • Uneven loading of the bearing.
    • Severe inner race hoop stress.
    • Insufficient support (back-up) of the inner race on the shaft.
  • All of these conditions could lead to premature bearing damage. Therefore, the manufacture, maintenance and measurement of accurate shaft tapers is important.
  • There are two accepted ways of measuring tapered shafts: ring gages and sine bar gages.
  • Precision measurement of tapered shafts is difficult with ring gages and may be impossible in the case of large shafts where gages are large, cumbersome and heavy.
  • Sine bar gages provide an accurate and easy method of measurement.
  • Lightweight and easy to handle and learn, sine bar gages achieve precise gagging of the shaft size and taper.
  • A complete set for measurement of 1:12 shaft tapers consists of 3 in, 4 in, 5 1/2 in, 7 in, 10 in and 14 in sine bar gages, sine bar saddle no. T-5491-C, web clamp no. T-5489-A and a wooden box no. T-5224-C. A complete set for 1:30 shaft tapers consists of 4 in, 6 in, 8 in and 12 in sine bar gages.
  • Sine bars can be purchased individually, or in any combination of sizes to meet your individual needs.
  • All sine bars require a sine bar saddle and web clamp. A wooden box is optional.
  • For information on the use of sine bars, prices and delivery, consult your Timken representative.
