1:Deep Groove Ball Bearing Information:
Single row radial ball bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads. This design permits precision tolerances even at high speed operation. Shielded bearings are protected on one, or both sides (suffixes Z and ZZ, respectively) by metal shields fastened to the outer ring. This close clearance labyrinth seal retains the lubricant and prevents the entrance of foreign matter. Sealed bearings incorporate steel reinforced rubber seals securely fastened to a groove on the outer ring. Contact with the inner ring is by sealing lip (Contact Suffix LLU). Or, non-contact with the inner ring is by labyrinth seal (Non-contact Suffix LLB) to provide positive sealing at all times.
2.The Protection of Deep Groove Ball Bearing:
1.The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
2.Don't allow strong impact, such as hammer striking, transfer roller pressure
3.Use the accurate installation tool, avoid to use cloth kind and short fibers
4.Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5.General inspection, such as the surrounding temperature, vibrate, noise inspection
6.Keep bearing cleaning from dirt, dust, pollutant, moisture.
7.Bearing should not be ultra cooled.
3:The Application of Deep Groove Ball Bearing
This bearings can be used: After sewing equipment, machine tool spindles, plug-in, ordinary type cooling tower, resistance welding machine, aging furnace, hobbing machine, environmental protection equipment, whirlpool pump, ceramics engraving machine, metal packaging machinery, fishing machinery, high pressure reactor, offset printing, aerospace, rubber granulating machine, plastic machine, chip conveyor, and so on purpose.
