Bearings Product List and Ranking from 111 Manufacturers, Suppliers and Companies

What kind of effects occur when an imbalance happens?

Are you experiencing a decline in machining accuracy when using machine tools such as grinding machines, machining centers, and lathes?

When an imbalance occurs, centrifugal force is generated, the rotation axis bends, and the rotating body describes an eccentric path, resulting in significant vibrations throughout the equipment. The occurrence of vibrations leads to the following phenomena: Due to the vibrations, the tool does not make uniform contact with the work surface, causing chatter marks and deteriorating machining accuracy, which increases the number of dressing cycles for the grinding wheel and increases the load on end mills and inserts, thereby shortening their lifespan. Primarily, the bearings are subjected to load, and it may become necessary to replace the bearings. **Effects of Imbalance:** - Deterioration of machining accuracy - Shortened tool lifespan - Damage to equipment *For more details, please refer to the PDF document or feel free to contact us.*

Slew bearing (turntable bearing)

Turntable bearing

■ A single slewing bearing can simultaneously support thrust loads, radial loads, and moments. ■ Generally, either the outer ring or the inner ring of the slewing bearing is directly machined for gears, allowing for drive slewing by a pinion. ■ The outer and inner rings are machined with through holes or tapped holes for bearing installation, making it easy to assemble and disassemble the bearing, thereby simplifying the structure and reducing maintenance effort.

[Web Seminar] Mechanism of Electric Corrosion in Rolling Bearings and Countermeasures

Highly praised 4th edition! New items and insights added. Detailed explanations of theory, experimental conditions/results/graphs/photos, discussions, and countermeasures in 200+ slides.

Rolling bearings are sometimes referred to as the "rice of machines," analogous to the Japanese diet, and they are essential mechanical components in constructing mechanical systems. In mechanical design, selecting rolling bearings according to the specifications of the machinery is part of the job, but failing to understand the fundamental principles can lead to significant mistakes. Recently, as the control of motor rotation speed using inverters has become widespread, electrical corrosion has also been observed in household appliances. Electrical corrosion is not a form of mechanical damage. Moreover, the design of rolling bearings should not allow electricity to flow internally, so when electrical corrosion occurs, the cause is often unclear. This seminar will explain the conditions under which electrical corrosion occurs, the observation of the ridge mark growth process, and methods to prevent electrical corrosion. A seminar specifically focused on electrical corrosion in rolling bearings is rare, and I hope to make it a meaningful experience for all participants.

Oil-containing bearing "Polite CLB"

Oil-impregnated bearings that significantly increase the oil content compared to conventional bearings, enabling longer lifespan.

"Polite CLB" is a material that has significantly increased the oil content compared to conventional materials to enhance reliability in applications that require particularly long lifespans, such as fan motors. By using a special method to create copper-coated iron powder and through special sintering, the matrix strength is improved compared to traditional bearing materials, and fine pores are created to achieve low air permeability. As a result, even with a high oil content, it provides bearing performance equivalent to conventional bearings. [Features] - High oil content improves reliability for applications requiring long lifespans. - Low air permeability allows for equivalent air permeability to conventional bearings even with high oil content, enabling comparable bearing performance and reducing oil leakage. - The bearing surface is covered with a copper alloy, providing excellent compatibility and corrosion resistance despite being iron-copper based. - The underlying material is iron, which suppresses wear progression after initial settling. - Switching from bronze-based bearings allows for cost reduction, among other benefits. *For more details, please download the PDF or contact us.

Oil-impregnated bearing "Polite DMP"

Oil-impregnated bearings suitable for low speed and high load conditions.

"Polite DMP" is an oil-embedded bearing that enhances a copper alloy matrix by uniformly dispersing a solid lubricant, graphite, in large quantities, thereby reducing metal contact during sliding and improving durability under harsh operating conditions such as low speed, intermittent use, and high load. Due to the high content of solid lubricant, it excels in wear resistance under high load and low speed conditions compared to iron-based and conventional bronze materials, resulting in superior durability. 【Features】 ■ Being based on a copper alloy, it has less galling with shafts and offers high reliability. ■ Can also be used for oscillating motion specifications. ■ This bearing is used by press-fitting into the inner diameter of gears and pulleys and can be used under shaft fixation conditions (please consult a technician). ■ It is also possible to use it without oil in places where oil is undesirable (please consult a technician). ■ Compliant with ELV and RoHS. *For more details, please download the PDF or contact us.

A customer has inquired, "I want to upgrade the specifications of the spindle!"

A clear explanation of the key points to consider when selecting bearings!

We received a request from the customer in charge saying, "I want to increase the spindle speed, but I would like you to confirm if the current angular ball bearings are okay." To gather more detailed information, we conducted a hearing with the customer, and they asked questions such as, "If we increase the speed, do we also need to consider the load?" and "Should we also consider the contact angle?" *You can view the detailed content of the blog through the related link.
