|Q1: Are the rolling element bearings RoHS compliant?|
A1: All of rolling element bearings are RoHS compliant. RoHS stands for the Restriction of
Hazardous Substances directive adopted by the European Union (EU) and took effect in July ( 2006).
|Q2: How do I get a copy ISO 9001:2008 certification?|
A2: Just ask for the most up-to-date ISO 9001 certificate! Contact us either by phone at or
contact us via email form.
|Q3: Can bearings be refurbished?|
A3: Generally speaking, for small bearings it is uneconomical to attempt to refurbish a
bearing product. However, for larger size bearings (6 inch bore and above) there potentially
could be economic gains.
|Q4: What's the difference between bearing seals and shields?|
A4: Seals and shields are both in place to keep contaminants out of a bearing. In order of
effectiveness, the enclosures that are offered are as follows: metal shields, rubber
non-contact seals, Teflon non-contact seals, and rubber contact seals. Not surprisingly, as the
sealing performance is increased, the torque required to turn the bearing will also increase due
to the increased friction caused by the seal/shield. The application's condition and life
requirements are important to know to determine the best shield or seal choice.
|Q5: What are ABEC ratings?|
A5: The ABEC scale is an industry accepted standard for the tolerances of a ball bearing.
It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing
Manufacturers Association (ABMA). There are five classes, going from widest tolerances to
tightest: 1, 3, 5, 7, and 9. Higher ABEC classes provide better precision, efficiency, and
greater speed capabilities, but do not necessarily mean that the bearing can spin faster.
Additionally, the ABEC rating doesnot specify many other critical factors, such as smoothness of
the rolling contact surfaces, ball precision, and material quality.
|Q6: Does a higher ABEC rating mean a quieter bearing?|
A6: While there may be a loose correlation between ABEC precision ratings and noise, higher ABEC
ratings to not always mean a quieter bearing. ABEC ratings do not specify many other critical
factors, such as smoothness of the rolling contact surfaces , ball precision, and material
quality all which may affect noise.
|Q7: How can I ensure I select the right bearing for my application?|
A7: We strongly suggests that you contact one of our bearing application engineers at the time
you select your design specifications. We offers an experienced sales and engineering staff to
help in the design and selection process, maximizing performance, and ensuring your success.
|Q8: What are "precision" versus "high-precision" ball bearings?|
A8: "Precision" and "high-precision" are generic bearing terms; however, there is no official
definition for either in the bearing industry. Generally speaking, "precision" ball bearings
comply with ABEC-1 and ABEC-3 tolerances while "high-precision" ball bearings comply with ABEC-5, ABEC-7, or ABEC-9 tolerances.
|Q9: Bearing Shelf Life - What is the shelf life of a bearing?|
A9: The most important factor for determining the shelf life of a "properly stored" bearing is
the lubrication. Greases and oils do have shelf lives (expiration dates).
|Q10: What bearing grease is the "best?"|
A10: The selection of the best bearing lubricant (whether grease or oil) will depend on the
application conditions. With a wide variety of greases and oils available, solutions are available for
most applications; however, there is no perfect grease whether natural, synthetic, micro-filtered or otherwise.
|Q11: Does NPBearings offer custom or made-to-order bearings?|
A11: NP Bearings has the ability to have many types of specialty bearings (not listed in our
catalog) manufactured to your specifications. For more information, please visit our web page
regarding Special Dimension Bearings and Custom Bearings.
|Q12: Will a stainless steel bearing protect against rust?|
A12: Stainless steel is not rust proof, it is "corrosion resistant" and will rust in corrosive
environments over time. However, stainless steel will corrode at a much slower rate than chrome
alloy steel. But it is not a simple as that.
|Q13: How fast can a bearing rotate?|
A13: NPBe arings offers bearings that are capable of rotation in excess of 500,000 RPM. These
are typically used in
|experimental and defense applications.|
|Q14: How is bearing material hardness measured?|
A14: There are several standard scales for measuring a material's hardness including Rockwell,
Brinell, Vickers, and Shore. For bearings, the Rockwell scale is predominantly used. However,
even within the Rockwell Hardness Test, there are several different scales used to specify the
hardness of different materials.
|Q15: What are flanged ball bearings?|
A15: Many ball bearings have flanges as options to their configurations. The flange is designed
aid in mounting and positioning. This is especially true for miniature and instrument bearings but
applies to other ball bearing types.
