Bearing The Selection Of Material

The ring and balls of ANJQ bearings are made of refining steel GCr15(AIS152100),the retainerare

punched from brassstrip(H62)ortop quality cold-rolled steel strip(SPCC BQB402)and reinforced

plastics are avail-able if necessary.Theshield is made ofimported special material (SPCCJISG314),sealing ring adopts phosphatingframed and fiber-like oiresistant rubberhot-pressingis

made.
