.Double row raceway which are better uniform and accurate are in one ring , better than paired single row bearing .
.Well sealing,prevent water vapour, corrosive gases intrude into the bearing and prevent the grease leak out , means maintenance free during its life time, our bearings run with low noise , high precision , high speed because well lubricated by pregreased.
.Support radial load and fairly degree of axial load
.According to the temperature, humidity , cleanliness which the equipments served by the motor will face to , RPM speed , force bring to the bearing , bearing components material,tolerance grade , heat treatment method,internal play,grease,parameters of raceway…will be considered professionally and comprehensively.
.For example , normally chrome steel GCr15/SAE52100/DIN100Cr6 is used for rings , NBR,HNBR/Viton FPM/ACM for seals , steel ribbon/Nylon PA/PTFE/PEEK/Brass for the cage, chrome steel/stainless steel/Ceramic ZrO2 Si3N4 for the balls . Sometimes hybrid is designed if necessary .
.Internal play can be C2,C0,C3…..or special data according to engineering.
.Our bearing normally operating temperature range -30°C to +110°C . With different material/heat treatment/grease…..will be wider range , consult us for more detailed information if you need.
.For special requires , extreme high/low temperature , insulation , anti-corrsion,RPM…… consult to us.
.Each piece product from us is customized based on customer’s demand to the bearing, our action guiding goal is engineering and supply them with top quality&best price.
.We are partnership supplier to ODM/OEM/wholesaler , we are unsung heros, supporting machines running in every corner of the world.
