"Technical", "Top", "True", "Trend", "Thanks"…"T" stands for everything "TBB" wants to share with our customers
From 2009 to 2019, it has been 10 years since TBB Shanghai office estabilished.With 10 years growth, no matter wind or rain, the way we go together, the warmth hidden in the bottom of every TBB member’s heart. Lisa, Sales General Manager in TBB, also the elder sister of TBB lady team. Under her leadership, TBB Bearing Provision is moving forward steadily. Let’s see what Lisa wants to say at this special occasion Heidi, Customer Mark...
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, s...
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 ...
If you are a cyclist looking to make your bike lighter and help you boost your cycling performance, easily make it possible by upgrading to Ceramic/Hybrid Bearings. TBB Ceramic and Hybrid bearings are specially designed for bicycle related applications such as wheel hubs, bottom brackets, and chain tensioner pulleys, etc. They have been proved to reduce riders pedalling watts. We use G5 grade ceramic balls, to meet up to highest cycling...
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 ...
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...
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 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...
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 ...
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...
