Cov bearings yog li tshwj xeeb tshaj yog haum rau lub tshuab cuab yeej spindles qhov twg cov kabmob kev npaj yuav tsum haum rau hnyav radial loads thiab high speeds, thaum muab ib tug high degree ntawm nruj, ob chav kab bearings yog haum rau hnyav loads.

Ob chav kab cylindrical cov menyuam bearings muaj ob lub qauv: cylindrical puab bore thiab conical puab bore (cov kabmob rear code ntxiv rau K). Lub conical puab lub qhov tseem tuaj yeem ua lub luag haujlwm ntawm micro-hloov ntawm kev tshem tawm, thiab tuaj yeem ua kom yooj yim rau cov qauv ntawm cov cuab yeej muab tso rau thiab pab txhawb kev teeb tsa thiab disassembly.

Feem ntau siv ob kab cylindrical cov menyuam bearings muaj cov nram qab no hom: NN series, NNU series, thiab NNF series.Tolerances: SP, UP, SP thiab UP rau 1:12 tapered bore.

NN3012KTN / SP Super-precision Ob chav kab cylindrical cov menyuam bearing Suffix piav qhia
K: Tapered Bore, Taper 1:12
TN: PA 66 kab
SP: Tshwj xeeb Precision Class Rau Tshuab Tool Bearings: Dimensional Accuracy Kwv yees li P5, khiav qhov tseeb kwv yees li P4

Super-precision cylindrical cov menyuam bearings yog tus cwj pwm los ntawm:
Muaj peev xwm ceev
High radial load nqa peev xwm
Siab rigidity
Kev sib txhuam qis
Tsawg ntu ntu qhov siab
