ROBUST Series（BNR、BER）
To achieve high speed applications, low temperature rise, ultra-precision processing and the development of high-performance series· There are two kinds of contact angle 18 ° (BNR), 25 ° (BER)
· There are two balls ball material (S), ceramic balls (H · X
· There are two outer cage guided phenolic resin cage (T), rolling guided polyamide resin cage (TYN), can be selected according to different purposes.
· 3,000,000 hypervelocity field ROBUST series also correspond to exceed dn value.
