TruKey® Shafting from Keystone is designed to provide the straightest, most accurate keyed shafting, in the industry. We stock pre keyed shafting in many diameters, including metric diameters, with standard keyways. We can provide keyed shafts in any length up to 20 foot. All keyed Shafting is guaranteed to fit on a bearing, and the ends can be chamfered for easy . As noted above, when selecting a keyway tolerance, there are two common selections in the metric system. The first is Js9. This is a +/- band clearance; the value of the tolerance is equally oversized or undersized. The second is a P9 tolerance. This is an undersized clearance. The advantage of the Js9 tolerance is that the key can be. Detailed width tolerance information is best drawn from the manufacturer. Inch (ANSI/AGMA .

The advantage of the Js9 tolerance is that the key can be inserted and the gear manipulated without much difficulty. Whereas the P9 tolerance is a press fit tolerance. Once the key is inserted into the keyway, it is not going to move. For those engineers who wish to put a square peg Estimated Reading Time: 2 mins. Hub keyway depth is one-half the nominal height of the key and measured from the side corner. The dimension from the top of the keyway to the opposite bore side, “T-dim”, is calculated from (refer to ANSI/AGMA B04) the following: T = bore + (h kw - Ch) Created Date:File Size: KB. 64 rows · bottom of shaft to bottom of keyway width reference depth Avoid tolerance buildup by dimensioning from another dimension, as cumulative tolerances will lead to dimensional errors.
