Siffofi: Duk sinadaran sun dace da ƙa'idodin aminci na abinci kamar NSF H1, kuma ba su da guba kuma ba su da ƙamshi.
Aikace-aikace: Bearings na injunan sarrafa abinci, injunan magunguna, da layukan cike abin sha don hana gurɓatar samfura.
Iv. Yadda Ake Zaɓar Man Shafawa Mai Daidai?
Lokacin yin zaɓi, ya kamata a yi la'akari da ƙa'idar "STAMP" sosai:
S-Speed (Speed):Da zarar saurin juyawa ya yi yawa, to, ƙarancin ɗanɗanon man tushe, to, ya kamata a zaɓi daidaiton injina da laushin daidaito don rage zafin da ake samu yayin juyawa.
T - Zafin jiki: Yanayin zafin aiki yana ƙayyade nau'in man fetur (man ma'adinai/man roba) da kuma nau'in mai kauri.
A-Aikace-aikacen/Yanayin Yanayi:Akwai ruwa, ƙura ko sinadarai? Wannan yana ƙayyade buƙatun juriyar ruwa, hana tsatsa da juriyar tsatsa.
M-Loda (Loda):Ya kamata a zaɓi man shafawa mai hana lalacewa mai ƙarfi don ɗaukar nauyi ko nauyin bugu.
Lokaci (Zagayen shafawa):Idan kana son tsawaita zagayowar canza mai ko kuma cimma aikin da ba shi da kulawa, ya kamata ka zaɓi man shafawa mai amfani da man shafawa ko man shafawa mai amfani da polyurea mai tsawon rai.
Zaɓar man shafawa mai ɗauke da sinadarai fasaha ce ta daidaito. Daga man ma'adinai da aka yi da lithium na tattalin arziki zuwa man shafawa mai ƙarfi na polyurea/complex calcium sulfonate, tsarin rarrabuwarsu kai tsaye yana dacewa da yanayi da ƙalubale daban-daban na aiki. Zaɓin da ya dace babban haɗi ne don tabbatar da ingancin bearings da tsawaita tsawon rayuwarsu.
