A GROWING NUMBER OF “BARGAIN” BEARINGS are being brought into the Heavy Duty Truck and Trailer marketplace by bearing brokers whose primary emphasis is on price. They ignore the critical issues of product integrity, performance, and supplier support. Initially the price has some attraction, but testing performed by Hyatt and other major suppliers has proven that a much superior performance is achieved from a quality product provi...

Wheel hub problems are often discovered while ruling out other sources for the squealing and grinding sounds coming from that area of the vehicle or the gradually increasing vibration noticed by the driver. Because such symptoms – odd noises, vibration, deterioration in handling, etc. – The common to a variety of suspension and steering system parts, it is often through the process of elimination that the need to replace this part is apparent...

Stainless steel and chrome steel are normally corrosion-resistant, not easy to rust. However, improper storage or handling at high humidity, condensation environment will reduce bearing life. How does the corrosion of bearings happen? If the bearing is prolonged exposure to water can cause rust. With the passage of time can cause peeling and crack formation, which are premature bearing failures. In addition, if the bearing is too loose or imprope...

The manufacturing of metal parts and components is so significant to any economic marketplace, typically, the machine tool industry is utilizing the latest technological advances in manufacturing processes. Here we’d like to talk about machine tool SPINDLE BEARING Most spindles use a combination of angular-contact ball bearings and cylindrical roller bearings. The angular-contact types install at a spindle work end because they handle both ...

TBB Track Roller is a bearing unit composed of machined thick-wall outer ring, needle rollers or cylindrical roller sets, or cage guidance or full complement needle roller, inner ring or bolt and seal. Featuring multiple compact structure, high rotating accuracy, large varieties, broad adaptability and easy installation, it can bear high radial load and certain shock load and is widely used in machine tool, metallurgical, textile and printing mac...

Whether you use cam follower bearings for cam followers, or for track, guide, or support rollers, their performance depends largely on the type you select. Important factors include loads, speeds, misalignment, installation, and lubrication. Cam follower bearings are used mainly in three types of applications: following the surface of a cam, supporting linear motion components, or laterally locating components during linear movement. Of these, ca...

Needle bearings are roller bearings with rollers that have high length-to diameter ratios. They are used in farm and construction equipment, automotive transmissions, small gasoline engines, gear pumps, small appliance and tool motors, alternators, and aircraft controls. Needle bearings are roller bearings with rollers that have high length-to diameter ratios. They are used in farm and construction equipment, automotive transmissions, small gasol...

Most rolling-element bearings are either ball or roller bearings. The roller bearing family consists basically of cylindrical, tapered, spherical, and needle bearings. Needle roller bearings are the smallest and lightest of the roller bearing family. That gives them specific advantages for certain applications, particularly those requiring reduced weight and space. The high roller length-to-diameter ratio helped give the bearings their name as we...

Heat Treatment of Bearing Steels

When bearing steels are in their soft (unhardened) state, metallurgists refer to their structure as being in the pearlite state. In order to harden the steel it must be heated to a very high temperature and then cooled very rapidly. When heated in the heat treat furnace to 1,750°F, the structure transforms from pearlite to what is known as austenite. After quenching (very rapid cooling), the structure then transforms from austenite to ...

The Advantages of Self-Lubricating Bushings

Self-lubricating bushings are used where the bearing must operate without lubricant or with marginal lubricant. Our focus is on ensuring that the bearing gives the best performance and the longest life under various conditions. The working principle of self-lubricating bearings is that, during the initial run-in period of the bearing, there will be a solid lubricating film created by the transfer of a small amount of material from the...

Service Life of Spherical Plain Bearings

In our previous blog entry, we examined static and dynamic load ratings for spherical plain bearings. This week, we continue our look into this bearing segment with some further information on the operating life of spherical plain bearings, and factors which can shorten or extend their use. The service life of a spherical plain bearing operated under mixed or dry friction conditions is determined by the increase in bearing clearance o...

Dynamic and Static Load Ratings for Spherical Plain Bearings

Dynamic and static load ratings for spherical plain bearings are important for understanding the life of a bearing, but what do each specify? Read on to learn more about these important classifications. Dynamic Load Rating for Spherical Plain Bearings Dynamic load rating is used for calculations when the spherical plain bearing is subjected to dynamic stress. It represents the load, constant in magnitude and direction, under which a bas...

Bearing FAQs

We have assembled a wide variety of frequently asked questions (FAQs) about bearings (e.g. ball bearings, roller bearings, plain bearings, linear bearings) and bearing related products (and bearing services too). Just refer to the question you’re interested in below and you will be taken to a remarkably succinct, straight-forward, and accurate answer: Q1: Can bearings be refurbished? Yes, but it depends… Generally speaking, for ...

Bearing rings and rolling elements materials

1) High carbon chromium bearing steel High carbon chromium bearing steel specified in JIS is used as a general material in bearing rings (inner rings, outer rings) and rolling elements (balls, rollers).Their chemical composition classified by steel type is given in “Table 13-1 Chemical composition of high carbon chromium bearing steel”.Among these steel types, SUJ 2 is generally used. SUJ 3, which contains additional Mn and...

Materials used for cages

Since the characteristics of materials used for cages greatly influence the performance and reliability of rolling bearings, the choice of materials is of great importance. It is necessary to select cage materials in accordance with required shape, ease of lubrication, strength, and abrasion resistance. Typical materials used for metallic cages are shown in Tables 13-3 and 13-4. In addition, phenolic resin machined cages and other synth...

Storage of bearings

In shipping bearings, since they are covered with proper anti-corrosion oil and are wrapped in antitarnish paper, the quality of the bearings is guaranteed as long as the wrapping paper is not damaged. If bearings are to be stored for a long time, it is advisable that the bearings be stored on shelves set higher than 30cm from the floor, at a humidity less than 65%, and at a temperature around 20℃. Avoid storage in places exposed dire...
