A new series of two-piece clamps for retaining gears on shafts, introduced by Sterling Instrument, provide installation when neither end of the shaft is available to slide on the clamp. The S3402Y-C225 to S3402Y-C236 two-piece balanced gear clamps feature circular outer contours to provide a way to avoid inducing vibrations in individual gears or gear assemblies. The clamps are made of two separate sections held together by two supplied cap screws. They can be installed in the middle of a shaft without disturbing the end components, and can hold a gear by squeezing the split hub of the gear against the shaft. The clamps are capable of gripping the shaft without marring it, and their circular outer surface minimises rotational imbalance. Made of 303 stainless steel, or anodised 2024-T351 aluminium, the clamps are available in two widths, 0.156 and 0.250in, for use on shafts ranging in diameter from 0.125 to 0.313in. The two clamp diameters offered are 0.875 and 0.5625in.
