There are three matching methods for angular contact ball bearings: series (DT) back-to-back (DB) and face-to-face (DF). The most common one is DT/DB pairing.
Tandem (DT): 1. The two bearings are the same and the installation direction is the same; 2. Can bear radial load; 3. The self-aligning ability is weak and the ability to withstand large overturning moments is poor.
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. Poor self-alignment ability and poor ability to withstand high overturning moments.

bearing
Engraving machine spindle motor bearing high speed seal P4 P5 7002DB series electric spindle bearing.
The integral seal greatly extends the service life of the bearing keeping the lubricant in the bearing and keeping the contaminants out.
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.
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 precision.
Lower noise higher load resistance higher cost performance and higher requirements for high and not easy to disassemble equipment can save a lot of costs.
Rubber dust cover type
Both sides with rubber dust cover factory has been filled with grease
High speed has good wear resistance
Rigorous design and manufacturing process products with higher precision less friction
Small friction coefficient and high precision
Higher speed and more wear-resistant suitable for high requirements
Lower noise and longer life span
Compared with the same category of bearings the noise is smaller and the life is longer.
Application industry
Can be used for mechanical and electrical aerospace cars trucks engineering machinery CNC machine tools and so on many industries.
