T-Blog, Your Bearing Wikipedia

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 Marketing Director in TBB . With her 8 yearsgrowing in TBB Shanghai office, what does she have in mind to share with us? Besides these, how many beauties can you recognize in below video? P.S. We are launching a campaign of collecting fingerprints and signatures from our clients who supported TBB all the time, which will be printed on our souvenir bags. It would be a great honor to us if you’d like to join us. Request: Fingerprint and signature need to be separated.                Signature–Black color. Fingerprint–no limitation (Expect Black)

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 gasoline engines, gear pumps, small appliance and tool motors, alternators, and aircraft controls. Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty bearings never require relubrication, but high loads or speeds demand it. Compared with other roller bearings, needle bearings have much smaller rollers for a given bore size. They have the highest load capacity for a given radial space of all rolling-element bearings, but their use is limited to bore diameters less than 10 in. All needle bearings are variations of two basic designs. The first, full complement, has a full complement of needles and contains no retainer. The second, caged needle, contains a retainer or cage for roller guidance and spacing. Caged bearings have smaller roller complements and lower load capacities than full-complement bearings. Their…

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 well as their operating characteristics. Essentially, needle roller bearings have: • Higher load capacity than single-row ball or roller bearings of comparable OD.• The ability to handle a larger, more rigid shaft in a given application.• Excellent rolling characteristics within a small cross section.• Generally lower cost, especially for the drawn-cup type compared with machined versions. Needle rollers The most economical type of needle roller bearing is a full-complement of loose needle rollers assembled directly between a hardened and ground shaft and housing. Generally, hardened end washers provide axial location. This type appears in many applications such as those where a hardened and ground gear bore serves as the outer raceway. When application requirements are met and assembly is not difficult, a full complement of rollers forms a bearing of small cross section and high load capacity. It…

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 requirements and bearing clearance which can meet up to a smooth and durable longer life time. Ceramic Balls have many advantages compared to Steel Balls. Bearing with ceramic balls can increase bearing performance and extend bearing life when used on high speed application or in a chemical, vacuum or high temperature environment. We offers Si3N4/ZrO2 Ceramic balls for use in loose ball wheel systems, such as wheel hubs. Features of Ceramic Balls Much lighter weight (Si3N4 ball only 40% weight of steel ball). Lower torque needed for pedal. Lower thermal expansion, excellent mechanical property at high temperature. Works in low lubrication condition. TBB can provide ceramic balls with dia.: 2.38mm(3/32″), 3.175mm(1/8″), 3.969mm(5/32″), 4.763mm(3/16″), 5.95mm (15/64″), 6.35mm(1/4″), etc.  Ceramic Ball Materials include: Si3N4, ZrO2, Al2O3, SiC, etc.
