Re: Shaft Machining Tolerance Limits
Belt conveyor pulleys manufactured today in Elecon ... within limits specified in IS: 8531. Pulley shafts. Special CNC machines ensure accuracy and consistency for machine shafts. ■
Re: Shaft Machining Tolerance Limits
Dear Eperts,
It is possible to purchase conveyor rollers ( idlers ), without drawings, by mentioning only the IS number & idler length & type.
Is it possible to purchase conveyor drive & driven pulleys also in similiar fashion? Has such standardisation available anywhere? If available, request to post the relevant data or links.
Thanking you & Regards, ■
Re: Shaft Machining Tolerance Limits
Tolerance of a basic size for specific tolerance grade.
The tolerance of a size is defined as the difference between the upper and lower limit dimensions of the part.
The system ISO implements 20 grades of accuracy. Each of the tolerances of this system is marked "IT" with attached grade of accuracy (IT01, IT0, IT1 ... IT18).
Fields of use of individual tolerances of the system ISO:
IT01 to IT6 For production of gauges and measuring instruments
IT5 to IT12 For fits in precision and general engineering
IT11 to IT16 For production of semi-products
IT16 to IT18 For structures
IT11 to IT18 For specification of limit deviations of non-tolerated dimensions ■
