Large-volume OEM cooperation is welcome anytime.
Q1: What is the feature of Z metal shield compared with rubber sealed bearing?
A1: Z all-metal shield resists high gearbox oil temperature, will not swell or age from long-term oil immersion, mainly used for internal gearbox oil lubrication environments; rubber sealed bearings are for external shafts with grease lubrication.
Q2: Can B31Z-19 replace original matching bearings directly?
A2: Yes, inner bore, outer diameter and width dimensions are fully consistent, no modification to equipment housing or shafts required during replacement.
Q3: What lubrication mode is suitable for this bearing?
A3: Designed for gearbox circulating oil lubrication; if used separately, high-speed anti-wear gear grease is required for filling.
