Features: 1)The design of double-row angular contact ball bearings is similar to two-single-row angular contact ball bearings. It is non-separable type. The basic design does not have filling slots and can accommodate equal axial loads in both directions. The ones with a larger outer diameter have filling slots in one direction and have pressed steel or machined brass cage. Bearings with E design have high loading capacity. They also have filling slots on one side which allows incorporating large numbers of balls. 2)They are also available with shields (non-rubbing type) and seals (low friction and rubbing type) on both sides. They are filled with lithium based grease which can inhibit rust and operate from the temperature of -30癈 to 110癈. 3)Types: Open, ZZ, 2RS. 4)Material: Made of bearing steel (GCr15). 6)Standard: ISO 9000, GB/T307 5)Packing: Inner Packing:1pc/box, Out Packing: Carton Price term: FOB, CIF Payment: T/T, L/C Our products are good in quality, competitive in price and also complete in size.
