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. Deep Groove Ball Bearing Protection:
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: Deep Groove Ball Bearing Application:
This bearings can be used: After ing 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.
