BUS200 SERIES GUIDELINES
• BUS200 requires bearing support to maintain concentricity. Concentricity between the shaft and the housing bore should be less than 0.002" (0.05 mm) total indicator reading (TIR). • BUS200 clutches have the same outside diameters as the bearings shown in the table on the specifications page. Bore tolerance of the housing in which the clutch is assembled should be within the range shown in the table below.
• BUS200 Series Cam Clutch is shaft mounted, so the shaft on which the clutch is mounted must be hardened to Rc 56-60 and 0.059" (1.5 mm) case depth after grinding. Grind to 16 micro-inch finish. • The taper of this shaft should not exceed 0.0002" per inch (0.01 mm per 50 mm). • Mating keyway profile should be in accordance with ANSI B17.1-1967 (R 1998).
