[Sell] Thrust Ball Bearing |
 |
|
| FreeRun is a specialized manufacturer of Thrust Ball Bearing . Features : Thrust ball bearings consist of two precision washers (rings) and a ball complement spaced by retainer. They can besupplied with or without radius ball grooves in the rings. Thrust ball bearings are used under purely axial loads, and its speed is limited. According to the capability it falls into Single Direction Thrust Ball Bearings and Double Direction Thrust Ball Bearings, our thrust ball bearings are the particular type of the Single Direction Thrust Ball Bearings. Single Direction Thrust Ball Bearings Single direction thrust ball bearings have two washers, with grooved raceways. The curvature of the raceways is slightly larger than that of the ball. Out of two washers, one is shaft washer & the other one is housing washer. The bore of the shaft washer isof the shaft dia & the bore ofthe housing washer is slightly larger than that of shaft washer, to facilitate free rotation. These types of thrust bearings are mainly used where axial load conditions are too large to be accepted by radial bearings. They can accept purely thrust load in single direction & they are not suitable for speed applications. The thrust ball bearings are separable so that mounting is simple as the washers and the ball and cage assembly can be mounted separately. Applications: RC models, Automotive, electric motors, home appliances, construction machinery, transmission shafts, gear shafts, pups, Bicycle and various kinds of professional machinery. Catalog : Note: We also can supply the OEM service, and the packing can beindustry packing or by cilents' requests. The same size can be made of different materials, including: Stainless Steel thrust ball bearings Chrome Steel thrust ball bearings Ceramic thrust ball bearings Photos of our thrust ball bearings: with Stainless Steel Retainer with Brass Retainer with Ceramic Balls |

[Sell] Teflon Seal Bearings |
|
|
| FreeRun is a specialized manufacturer of Teflon Seal Bearings . Features : Teflon is a fluorocarbon based polymer with highchemical resistance, stability at low and high temperature, resistance to weathering, electrical andthermal insulation and extremely low coefficient offriction. The chemical name is Polytetrafluoroethylene which is better known as P.T.F.E or the name Teflon. Teflon is a very slippery material and causes very little resistance whenused as a seal. It is also extremely heat and chemical resistant.These seals offer increased sealing effectiveness over shielded (ZZ)bearings and almost the same effectiveness as nitrile rubber seals(2RS). Many bearings in our range are available with Teflon seals. Just lookfor the bearing suffix code2TS. Our Teflon seal bearings can withstand temperatures considerably higher and longer than silicone or buna rubber, they can provide abrasion and impingement resistance, and can protect from dust or any possible contamination, they are pre-lubricated bearings. The same size with teflon seals can be made of different materials, including: Stainless Steel Bearings Chrome Steel Bearings Carbon Steel Bearings Ceramic Bearings Applications: RC models (Radio control nitro and electric on-road cars, off-road stadium trucks, monster trucks and buggies), Jet Turbines, electronic motor, skateboard,scooter, etc. Catalog : Photos of Teflon Seal Bearings : 2TS bearing with flanged 2TS bearing with ceramic balls |

[Sell] Ceramic Miniature Bearing |
|
|
| FreeRun is a specialized manufacturer of Hybrid Ceramic Bearing. Full Complement ceramic bearings,Ceramic Balls. Hybrid Ceramic Bearing: Ceramic bearings offer a significant performance improvement from those made from traditional steel. Our ceramic bearings are manufactured from silicon nitride (Si3N4), an exceptionally hard non-metallic material rated for speeds to 2 million dN, offering a wide selection of benefits. Hybrid Bearings have steel rings and ceramic balls. Si3N4 Ball is the most popular for the balls as it has only 40 percent of the density of bearing steel but is much harder giving greater wear resistance. Zirconia is heavier with 75 percent of the density of steel so is less suitable for hybrid bearings.. FULL CERAMIC BEARINGS Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPMs, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC.) Ceramic Balls: We are special in making Silicone Nitride Balls (Si3N4 Balls,Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls , Aluminum Oxside Valve (AI203) ceramic balls. Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
