1. Cov rollers yog nyob rau hauv kev sib cuag nrog cov raceways, nrog loj radial bearing muaj peev xwm, thiab yog haum rau bearing hnyav thiab poob siab loads.

2. Kev sib txhuam coefficient yog me me, haum rau kev kub ceev, thiab kev txwv ceev yog ze rau qhov sib sib zog nqus groove pob bearings.

3. Cov qauv N thiab NU tuaj yeem txav axially, tuaj yeem hloov mus rau qhov kev hloov pauv ntawm tus txheeb ze txoj hauj lwm ntawm lub ncej thiab lub vaj tse vim thermal expansion lossis installation yuam kev, thiab tuaj yeem siv los ua kev txhawb nqa dawb kawg.Lub nplhaib sab hauv lossis sab nraud tuaj yeem sib cais kom yooj yim installation thiab tshem tawm.

4. Cov kev xav tau ntawm cov ncej thiab lub qhov rooj yog qhov siab.Tus txheeb ze deflection ntawm lub puab thiab sab nplhaib axes tom qab lub bearing yog ntsia yuav tsum tau nruj me ntsis tswj kom tsis txhob muaj kev sib cuag kev nyuaj siab concentration.

5.Double-kab cylindrical cov menyuam bearings nrog ib tug 1:12 taper hauv bore.Lub radial clearance tuaj yeem hloov kho thiab radial rigidity siab, uas yog tsim rau lub tshuab cuab tam spindle.
