5 IDE GUIDE NB CENTER-INED TAPPED SHAFT A larger diameter shaft can overcome problems in maintaining precision functionality when a high or unbalanced load is applied. The application of the center-lined tapped shaft together with the SA type support base is ideal in such cases (see SA dimensional table on pages E-32 and E-33). The center-lined tapped shaft is standardized to simplify selection. structure example SNSB 7 material SNB SUJ2 equivalent to SNSB SUS4C () (D) BA SPINE ROTARY BA SPINE TOPBA PRODUCTS SIDE BUSH SIDE UNIT N: -KP 2 K: of pitches SIDE ROTARY BUSH NB Center-ined Tapped Shaft pitch g* P m SNB10 10 /11 SNB SNB 14 SNB 1 SNB 1 7 SNB SNB SNB 9 SNB SNB bolt size M M 4 M 4 M 4 M M M M 8 M 8 M 8 M10 tap depth material: high-carbon chromium bearing steel (SUJ2) hardness: HV97 (0HRC) or more *g is standard tolerance for the. maximum max 1, 1, 2,000 2,000 3,000 4,000 4,,000,000,000 NB Center-ined Stainless Tapped Shaft pitch bolt size g* P M m SNSB /14 1 M SNSB 1 M 7 SNSB M SNSB M 8 SNSB M 8 9 SNSB M 8 SNSB M10 G-9 copyright 1 maryland metrics/nb corporation tap depth maximum max 2,000 3,000 4,000 4,,000,000,000 material: martensite stainless steel (equivalent to SUS4C) hardness: HV3 (8HRC) or more *g is standard tolerance for the.

6 NB products are available from: MARYAND METRICS FINE SHAFT The NB fine shaft is standardized as the most frequently used slide shafts with the NB slide bush. The diversification of industrial needs for rationalization, energy conservation, lower cost, etc. is proceeding rapidly. In such an environment, NB Fine Shafts are produced to maintain the highest quality and accuracy while lowering the component cost. structure example SNSF 7 material SF SUJ2(solid) equivalent to SNSF SUS4C (solid) SNTF SUJ2(hollow) total () (D) Fine Shaft (SF Type) SF SF 8 SF10 SF SF SF SF SF SF SF SF SF g m 4/ *JISB0 coarse-grade applies to the () material: high-carbon chromium bearing steel (SUJ2)hardness: HV97 (0HRC) or more G-10 copyright 1 maryland metrics/nb corporation
