.Single row deep groove miniature ball bearing , most popular used in electric motors .

.Perfect seals, prevent dust,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.

  ..Contact Sealed bearing is with perfect sealing , suitable for dusty environment. Maintenance-free.

..Non-contact rubber seal or shield,extremely light contact seal has balance point between good sealing and light torque.   

.Support radial load and a certain degree of axial load , slight misalignment allowable. (consult us for more detailed information)

.Fairly high RPM speed, for example in vacuum cleaner 608-2RS or 609-2RS , running up to 30000rpm~40000rpm.

.According to theconditions 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,CN,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 is customized based on customer demanding 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.
