Performance Characteristic of double row cylindrical roller bearing manufacturer

Cylindrical roller bearings with snap ring grooves are full complement, double row units comprising solid outer and inner rings with ribs,rib-guided cylindrical rollers and sealing rings. The outer rings have grooves for retaining rings. The inner rings 1mm wider than the outer rings and held together by a rolled-in steel strip. The bearings are available as a light series SL04..-PP and in the dimension series 50 as sl0450..-PP.

Sealing&lubricant Sealing rings on both sides protect the running system against contamination and moisture. The cylindrical roller bearings are greased with a lithium complex soap grease and can be relubricated via the outer and inner ring.Automobile, tractor, machine tool, electrical machine, water pump, agriculture machine, textile machine, etc.

 FRQ:

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, Tefl 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.

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: NPBearings 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: NPBearings 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 to aid in mounting and  positioning. This is especially true for miniature and instrument bearings but applies to other ball bearing types.
