508308 Deep Groove Ball Bearings Rolling Mill Bearing for Fruit Washers
Deep groove ball bearings are particularly versatile.They are suitable for high and very high speeds, accommodate radial and axial loads in both directions, and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from in many designs, variants and sizes. In addition to the bearings presented in this section, deep groove ball bearings for special applications are shown under:
Single row deep groove ball bearings
Single row deep groove ball bearings are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces .
Stainless steel deep groove ball bearings
Stainless steel deep groove ball bearings are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces .
These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.
Other type:
1.Single row deep groove ball bearings with filling slots
2.Double row deep groove ball bearings
3.Capped bearings
Shields (designation sufixes Z or ZS)
1)are primarily intended for applications
where the inner ring rotates
2)are itted in the outer ring and form a narrow gap with the inner ring
3)are made of sheet steel, or stainless steel
for stainless steel bearings
4)protect from dirt and debris without friction losses
Designation Z: either with or without an extension in the shield bore or on some stainless steel bearings, the shield bore can extend into a recess in the inner ring (c) Designation sufix ZS (stainless steel bearings only): fixed in the outer ring by a retaining ring and may extend into a recess.
Non-contact seals (designation sufix RZ)
1)provide better sealing effectiveness than shields
2)can be operated at the same speeds as shields
3)form an extremely narrow gap with the inner ring shoulder
4)are made of sheet steel reinforced NBR (oil- and wear-resistant)
Low-friction seals (designation sufixes RSL or RST)
1)provide better sealing effectiveness than non-contact seals
2)are made of sheet steel reinforced NBR (oil- and wear-resistant)
