2020年8月14日 · Example fits: H7/p6 for hole-basis, P7/h6 for shaft-basis. Using a 25 mm diameter, a H7/p6 fit gives a min interference of 0.001 mm and a max interference of 0.035 mm. Driving Fit. Needs higher assembly forces for cold pressing. Another way is by using hot pressing. This interference fit is more prominent than with a press fit.

Find your data faster with our Fits and Tolerance Calculator The Inch values shown in the table are conversion from the mertic values per ISO 286. you should expect about 0.1-0.5 thous errors wehn comparing with ANSI B4.1/4.2!

Complete charts for H7/h6 Clearance Fit per ISO 286, including size limits for hole and shaft and clearance classification data.

Calculation of fits and tolerances for shaft and hole per ISO 286-1 and ANSI B4.2. All tolerances classes and sizes according to standard.

SLIDING FIT: Not intended to run freely, but to move and turn and locate accurately H7/h6 LOCATION FIT: Snug fit for staitonary parts, can be freely assembled and dissassembled

H7/s6: S7/h6: Medium drive fit for ordinary steel parts or shrink fits on light sections, the tightest fit usable with cast iron. H7/u6: U7/h6: Force fit suitable for parts which can be highly stressed or for shrink fits where the heavy pressing forces required are impractical.

H8/j7, H7/js6,H7/j6, J7/h6 Tight fits with small clearances or negligible interference. The parts can be assembled or disassembled manually. Easily dismountable fits of hubs of gears, pulleys and bushings, retaining rings, frequently removed bearing …

The hole basis fits have four preferred hole tolerances (H11, H9, H8, and H7); the shaft basis fits have four preferred shaft tolerances (h11, h9, h7, and h6) as shown in Table 6-1. The above shaft tolerances are now covered in the new ANSI B32.100-2005 standard.

H8/h9, H8/h8, H8/h7, H7/h6 Sliding fits with very small clearances for precise guiding and centering of parts. Mounting by sliding on without use of any great force, after lubrication the parts can be turned and slid by hand.

3 天之前 · Some of the selected Preferred fits: H7/k6, H8/k7, K7/h6, K8/h7, Location/Transition; This fit for accurate location where greater interference permissible. It is fixed fits with small interferences or negligible clearances.
