Product Description

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. They are available in many designs, variants, and sizes for special applications.

Single Row Deep Groove Ball Bearings

Available capped (with seals or shields) or open. Open bearings may have recesses in the ring side faces.

Stainless Steel Deep Groove Ball Bearings

Designed for corrosion resistance. Note these have a lower load carrying capacity than high chromium steel versions.

Shielding and Sealing Options

Shields (Designation Z or ZS):

Primarily intended for applications where the inner ring rotates.
Fitted in the outer ring, forming a narrow gap with the inner ring.
Made of sheet steel or stainless steel.
Protection from dirt and debris without friction losses.

Non-contact Seals (Designation RZ):

Better sealing effectiveness than shields.
Operable at the same speeds as shields.
Made of oil- and wear-resistant NBR reinforced with sheet steel.

Frequently Asked Questions

Q1: What are the main applications for 6218-2Z/VA228 bearings?
A: These high-temperature/performance bearings are ideal for film manufacturing equipment and environments where radial and axial loads coexist at high speeds.
Q2: What is the difference between Z and RZ designations?
A: Designation Z refers to a metal shield that offers low friction and protection from debris. RZ refers to non-contact seals made of NBR, providing better sealing effectiveness than shields while maintaining high-speed capabilities.
Q3: Can these deep groove ball bearings handle axial loads?
A: Yes, deep groove ball bearings are designed to accommodate radial loads as well as axial loads in both directions.
Q4: Are stainless steel bearings better than chromium steel versions?
A: Stainless steel bearings offer superior corrosion resistance, but they typically have a lower load-carrying capacity than same-sized bearings made of high chromium steel.
Q5: What maintenance do these bearings require?
A: Deep groove ball bearings are known for being the most widely used bearing type partly because they require very little maintenance.
Q6: What precision standards are available?
A: These bearings are available in P4, P5, or standard ISO 9001:2000 precision levels depending on specific customer requirements.
