Q1: Yuav ua li cas kom paub meej 095000-6521 vs 095000-6520?
A: Tshawb xyuas dab tshos engraving. Rau 6520, piston ntev txawv ntawm 0.2 hli - cov khoom siv no yuav tsum muaj 22.05mm ± 0.02mm.

Q2: Lub neej kev pab cuam?
A: 8,000–10,000 teev (300k–400k mais) nrog roj huv. B20 los yog txias heev pib txo mus rau ~ 5,000 teev - kuaj xyuas cov dej xau- tawm ntawm 4,000 teev.

Q3: Kuv puas tuaj yeem rov siv lub caij nplooj ntoos hlav qub thiab piston?
A: Tsis yog- hnav tsis sib xws hloov pauv qhov sib npaug hydraulic, ua rau lub suab nrov thiab rov qab ntws siab. Kev teeb tsa ib nrab ua tsis tiav hauv 6 lub hlis.
