Frequently Asked Questions (FAQ)
Navigating the technical specifications of precision components can be complex. Below, we address the most common inquiries from engineering and procurement professionals regarding the 606 series.
What is the primary difference between the 606-2Z and 606-2RS variants?
The 2Z variant utilizes non-contact metal shields, offering lower friction and higher speed capabilities, making it ideal for clean environments. The 2RS variant features contacting rubber seals that provide superior protection against moisture and fine dust, though with a slight reduction in maximum limiting speed due to seal friction.
Can this bearing withstand axial loads, or is it strictly for radial applications?
Due to its deep groove geometry and close osculation between the balls and raceways, the 606 bearing is highly versatile. It can successfully accommodate moderate axial loads in both directions simultaneously with radial loads.
How do I determine the correct internal clearance for my application?
Standard CN (normal) clearance is suitable for most general applications. However, if your shaft operates at exceptionally high temperatures or requires a heavy interference fit, we recommend requesting a larger C3 clearance to accommodate thermal expansion and prevent premature seizure.
Are these bearings suitable for vacuum or cleanroom environments?
Standard GCr15 steel bearings with standard grease may outgas in a vacuum. For cleanroom or high-vacuum applications, we can customize the order with specialized low-outgassing fluorinated lubricants or provide stainless steel variants upon request.
What is the recommended mounting procedure to prevent raceway damage?
Bearings should always be installed using a specialized mechanical or hydraulic press. Force must only be applied to the ring being fitted (the inner ring for shaft mounting, or the outer ring for housing mounting). Never transmit mounting force through the rolling elements, as this will cause Brinell indentations and immediate acoustic failure.
