Double row angular contact ball bearings features and applications

    Chinabase Machinery is a group of manufacturing facilities, offering one-stop solution for mechanical power transmission products in China. We can supply a full-range of power transmissions products, such as chains,engineering chain, Agricultural Chain,sprockets and plate wheels, pulleys, gearboxes, motors, couplings, gears and racks. Our product range also covers locking assemblies (clamping elements/locking device), taper bushes, QD bushes, bolt-on hubs, torque limiters, shaft collars, motor bases and motor slides, chain detachers, chain guides, universal joint, rod ends and yokes,V-Belt Pulleys. Our products are used in many different industry sector, like in automation engineering, drive engineering, conveyor technology, assembly and handling technology, packaging industries, the beverage, food and medical engineering, pharmaceutical production, and laboratory equipment.
   Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load, limiting both the axis of the axial displacement. Main shaft and the housing for limiting the axial displacement member bidirectional.
   Structural variants
   (1) A type of bearing outside diameter less than or equal to 90mm standard design. Non-loaded ball gap, so they can withstand the equivalent of two-way axial load. Using lightweight glass fiber reinforced nylon 66 cage, bearing temperature rise is small.
   (2) A type of bearing outside diameter greater than 90mm standard design. Side of the ball gap, with a pressed steel cage or solid brass cage.
   (3) E-type structure is enhanced, the side with filling slots that can hold more of the ball, so the higher carrying capacity.
   (4) sides with a dust cover type and sides with a ring-type A-type and E-type design designed double row angular contact ball bearings can be on both sides with a dust cover (non-contact) or seal (contact ). Sealed bearings are filled with rust inside lithium grease, operating temperature is generally -30 ~ +110 ℃. No further lubrication during use, should not be heated before installation should not be cleaned.

Linear Bearing

   Application
   Single-row angular contact ball bearings, double row angular contact ball bearings with better rigidity to withstand the overturning moment. Bearing a non-split. There are especially suitable for applications that require high rigidity. Widely used in cars in the front wheel hub (some models also use the same size of the double row tapered roller bearings).
   Feature
   Double row angular contact ball bearings, the outer ring is limited between the tiltable, allowing the tilt angle depends on the bearing internal clearance, bearing size, internal design and acting on the bearing force and torque, while the maximum permissible tilt angle should guarantee bearing will not generate excessive additional stress.
   If the bearing inner and outer angle of inclination between will affect bearing life, also causing precision bearings running down, running noise increases. Double row angular contact ball bearings generally use nylon cage or solid brass cage. Double row angular contact ball bearing installation should pay attention, although bearings can withstand axial load, but if there is one side of the gap when the ball should be careful not to let the main axial load through the notched side of the gutter. Note that the bearing should be used without the ball gap to bear the main load side of the raceway.
