EMQ Bearings and Super Precision Bearings

Features:
1) Our EMQ bearings (single row deep groove ball bearings) can reach the 
    accuracy grade of ABEC3 (P6) and ABEC5 (P5), ZV3. They are suitable for 
    high speed, high precision, low friction and low noise operations, such as 
    household appliances, office equipment, electric appliance, electronics 
    equipment, optical instrument, medical instrument and others. 608, 
    6200~6208, 6300~6308, 693 are strongly recommended
2) Our high-speed & precision bearings mainly referred to matched angular 
    contact ball bearings at ABEC7(P4) and ABEC5 (P5). They have 
    characteristics of high rotary precise and high dimensional precision, 
    suitable for high-speed operating, like applying for motor spindles, 
    high-speed tool machinery and precise measure equipments. Their cages 
    are mainly made of phenolic laminated resin or glass-fiber reinforced 
    polyamide 66
