With our reputation among machine builders as a manufacturer of precision, high-performing products, Tracey Gear & Precision Shaft has fulfilled orders from companies all over the world. In this example we worked with a well-known European machine manufacturer to produce the link idler sprocket highlighted here. This project posed a number of challenges; the design includes tight tolerances and a high level of complex details that would require multiple machining processes, as well as precision grinding.

This modified 24 tooth, 1.5 Pitch, 0.867 roll sprocket was manufactured with only 12 teeth. The outside diameter of this 12 tooth design is 12.403. Other features include six through holes with -20 thread, and three 0.75 deep holes also with -20 thread, all of which had to be produced to tolerances of 0.005. Additionally, 45 chamfers were required along many of the edges. The machining processes required to complete this product include turning and extensive milling, surface and ID grinding were also key elements of production. Dimensional accuracy and overall quality checks were performed throughout all machining processes. Our production team is guided by a robust quality program; in this case our own comprehensive gear inspection procedure was utilized to ensure 100% conformance to the customers drawings.

By manufacturing products such as this that exhibit a very high caliber of quality, we earn the trust of our customers, who rely on us to supply them with superior parts within strict deadlines.

The ABS-HD series is adequate for grinding applications where pressureassist units are used to apply grindingpressure. Tension is provided by a heavy dutyair cylinder. The 9 dia. pulley is machined from an aluminum casting, & rotateson sealed ball bearings. The base of the unit is a weldment.

Toro Drop-In ReplacementThe TR-4 and TR-5 are dimensionally identical to the old To ro Backstand Iders. The Idler pulleys are crownedaluminum. 9 diameter, and 4 1/4 (TR-4) or 6 1/4 (TR-6) wide. Tension is supplied via two torsion springs.Tracking is adjustable by rotating the idler pulley shaft, screwing it in or out. These Backstand Idlers aredimensionally equivalent to the old Toro Backstand Idlers, enabling them to be dropped in as replacements.
