spacer Kaydon Bearings white papers

At Kaydon Bearings, we apply engineering experience and expertise to solve the world's most demanding bearing challenges. Take advantage of that expertise and learn more about thin section bearings, slewing ring bearings, and custom solutions, as well as bearing remanufacturing, in these Kaydon white papers and articles.


The importance of properly mounting thin section bearings
Thin section ball bearings have a much thinner cross-section than standard bearings of the same diameter, making them more sensitive to shaft and housing fits. The use of appropriate bearing styles, proper bearing orientation, recommended fits, and correct shaft and housing geometry help assure that a thin section bearing will achieve its full capacity. Find out which factors to consider when mounting radial, four-point contact, and angular contact bearings.

How mounting can optimize slewing ring bearing performance
Proper mounting is crucial to the correct distribution of bearing load and stress, and should be considered early in the design process. Without an adequate mounting structure, the performance of the bearing, seals, pinions, gears, and bolts is likely to suffer. Read about how to determine the correct bearing size, shrouding, and mounting structure; the importance of appropriate deflection and flatness; and how to mount the bearing to the mounting structure.

Trust but verify: the value of acceptance testing
For design engineers working in critical applications, acceptance testing is a kind of insurance policy: a little extra cost and time up front can help avoid expensive delays later. Acceptance testing measures torque, preload, runout, stiffness, and more to confirm whether or not these values are inside expected limits. Find out which applications benefit most from testing and how to develop an acceptance test plan.

Simplify designs with slewing ring bearings
Geared slewing ring bearings are a great solution for simplifying drive systems, especially when space is limited. Gear teeth can be cut into the inner race or outer race (stationary or rotating) to suit the application. Learn more about using the Lewis formula for tooth size and form selection and how to gain backlash room in a design, as well as the proper way to install a slewing ring bearing.

Bearing selection for low-speed applications
Low-speed applications, such as wind turbines, robots, cranes, gun mounts, and radar antenna mounts, can present bearing design challenges. Bearings may have special lubricant needs, require modification or need to be custom designed. Find out which types of bearings are typically used in low-speed applications and 10 key performance requirements designers should consider when specifying them.

Four-point contact bearings do triple duty while saving space
Four-point contact ball bearings are ideal for applications with oscillating movement at slow to moderate speeds. With a unique design and ability to handle radial, thrust, and moment loads, a single four-point contact bearing can replace two angular contact bearings. Learn more about the advantages of four-point contact bearings, including space, weight, and cost savings, and greater accuracy.

Bigger isn't always better: the case for thin section bearings
Thin section bearings are an excellent choice for applications requiring high stiffness, accurate positioning at low shaft speed, or a combination of radial, thrust, and moment loads. In many cases, a thin section bearing can do the job of a bigger, heavier bearing while providing space and weight savings. Learn more about thin section bearing sizes, configurations, and construction, and design considerations and maintenance practices, in this Kaydon white paper.

Nine questions to ask when specifying a slewing ring bearing
In applications that require a bearing to support a structure while it rotates (e.g. cranes, radar, tank turrets), premature bearing failure can put people and equipment at risk. The bearing's support structure, mounting, installation, and even storage are all factors in a bearing's success or failure. Find out what key questions a designer should ask when specifying a slewing ring bearing.

How to extend the life of your slewing ring bearings
Premature failure is a common fate for large-diameter bearings in heavy-duty applications. Fortunately, regular maintenance can prevent 96% of slewing ring bearing failures. Learn about a routine maintenance plan and the four warning signs of bearing wear or failure.

Stop bearing corrosion before it starts
Corrosion can have a serious impact on bearing life, negatively affecting a machine's performance, productivity, and operating costs. Fortunately, there are steps you can take during the design stage to protect your bearing throughout its life.

Key trends in bearing lubrication
Bearings and lubricants continue to become more advanced. Learn how to choose the right lubricant to achieve optimal efficiency.

Installing large diameter bearings on rotating equipment and oscillating applications
Many things can go wrong during and after installation of a large diameter bearing. Learn what simple steps you can take during installation to prevent costly mistakes.

Kaydon's new capacity calculations for thin-section bearings
Learn about Kaydon's method for calculating dynamic radial load ratings for thin-section ball bearings, using the contact stress and the number of stress cycles per revolution. The new method is more accurate, with new numbers proven by five years of test results.

Gearing up your bearings
Some drive systems can be simplified by incorporating a gear onto a slewing ring bearing. Read about the benefits, challenges, and proper installation of gear bearings.
