P4/P5 DT CNC Milling Machine Spindle Bearing 7002/7003/7004/7005/7007/7008C Sealed Angular Contact Bearings(7002-2RZ-P5,Pair)

BearingsThere are three kinds of pairing methods of angular contact ball bearings: series (DT) back-to-back (DB) and face to face (DF). The most common one is DT/DB pairing.In series (DT) : 1. The two bearings are the same and the installation direction is the same;2 can bear radial load;3. Weak self-aligning and poor ability to withstand higher overturning moment;Back to back (DB) :1 symmetrical installation;2 can bear radial load;3. Able to bear axial load in two directions;4 can withstand high overturning moment;Face to face (DF) :1 symmetrical installation;2 can bear radial load;3. Able to bear axial load in two directions;4. Weak self-aligning and poor ability to withstand high overturning moment;Bearings are the heart of machinery. Choosing a suitable bearing will greatly improve the production efficiency of mechanical equipment. High-standard bearings can reduce friction and have strong high temperature resistance during high-speed operation and overload operation. Bearing life and increase speed.Deep groove ball bearing is a product developed based on the concept of high hardness high load high rigidity and high precisionLower noise higher load resistance higher cost performance and higher requirements for high and not easy to disassemble equipment.Rubber dust cover typeBoth sides with rubber dust cover factory has been filled with greaseRubber cover seal: dust proof liquid foreign matter proof good mute effect suitable for harsh environment.High speed has good wear resistanceRigorous design and manufacturing process products with higher precision less frictionSmall friction coefficient and high precisionHigher speed and more wear-resistant suitable for high requirementsLower noise and longer life spanCompared with the same category of bearings the noise is smaller and the life is longer.

• Bearings
• Application industry: Can be used for mechanical and electrical aerospace cars trucks engineering machinery CNC machine tools and so on many industries.
• Bearing ring: Contains inner ring and outer ring.Made of high quality steel effectively extend the service life of bearings
• Rolling element: Transfer the load between the inner and outer rings
• Cage: Reduce friction heat: optimized load convenient disassembly
• Monolithic seal: Significantly extend the service life of the bearing keep the lubricant in the bearing and keep the pollutants out.
