Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized main bearing manufacturer and custom main bearings designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

These materials were developed as an improvement on the white metal and copper based alloys and to provide bearings that carry high loads. The disadvantages are only
moderate embedding properties, poor compatibility , and high coefficients of thermal expansion.
Special features include good resistance to corrosion, high thermal conductivity, and high fatigue strength. If used as solid unbacked bearings this type of alloy is usually too weak to maintain an interference fit and too hard to run satisfactorily against an unhardened shaft. It was found that 20% of tin added to the aluminum improved seizure resistance and that cold working and annealing helped to prevent brittleness.
As a bearing material unalloyed aluminum has a tendency to seize to a steel mating surface. The difference in coefficients between aluminum and steel necessitates work hardening the bearing before use to prevent loosening in service.

Built for the (91-99) Mitsubishi 3000GT-Stealth... Stock bearings are made for stock applications, but today's Imports are stretching the abilities of stock components and demanding much more.Toga HP Bearings are meeting those demands and extending the life of today's performance Import motors. *Most Toga HP Series Mains sets are full grooved to maximize oil flow to the rod bearing. Both rods + mains have a high crush for max retention and reduced overlay thickness to prevent *fatigue. Rod bearings use hardened steel backs for added strength. *Toga HP bearings should be used wherever high RPM's (above 6000), nitrous, superchargers, turbochargers or any application where above normal HP + RPM's are made. *All motors benefit from these HP bearings. These bearings will give longer life to any engine by increasing oil to the pins + eliminating oil starvation. *All bearings are Tri-metal cast copper lead with copper lead lining to withstand engine loads, along with electroplating babbitted overlay providing optimum service. All bearings are stamped with a red HP. *All bearings are available in Standard, 10 over and 20 over. *You can mix the main and rod sizes. *All bearings hand inspected and stamped. *All bearings weight in each set within .0001 grams.Bearings come with a 3 year/36,000 mile warranty. (Does not include racing motors. Warranty non-transferable)Sizes: All bearings available in STD, 10, 20 over. You can mix the mains and rods sizes.Note: ALL SALES ON TOGA BEARINGS ARE FINAL. NO REFUNDS / RETURNS ACCEPTED.
