1. Product Overview
VHC spherical Bearings/ Bridge bearing manufactured by Vinh Hung Investment and Production Company Limited (Vinh Hung IP) are capable of withstanding the high loads and movements suitable for structures requiring the rotary angle equal or bigger than 0.015 rad in all directions. VHC spherical bearings are designed and manufactured according to current standards such as:TCVN 11823, AASHTO LRFD, ASTM D5977, EN 1337,
2. Product Characteristics
VHC spherical bearings/ bridge bearing possesses a bottom plate (6) which has a PTFE sliding plate (4) on it is upper curved surface. A convex calotte (5) is placed on top of this, which, thanks to it is polished hard-chromium plated surface, can slide within the lower part with low friction, thus facilitating rotations about every axis.
A second sliding plate of PTFE (4) is recessed into the upper surface of the calotte. Together with the upper plate (2) above it, this accommodates longitudinal and/or transverse sliding movements of the superstructure, if required. To reduce sliding resistance to a minimum, the lower surface of the top plate features a polished stainless steel sheet.
In the case of bearings which should allow movement along one axis only, the direction of movement is controlled by guiding bars (3). In the case of fixed bearings, the top plate does not have a stainless steel sheet.
The bearing is connected to the superstructure and the substructure by means of anchor dowels (1) or threaded sleeves (depending on design), or alternatively by means of separate anchor plates with shear studs.
To ensure the long-life durability, VHC spherical bearings are protected against corrosion by the following methods: coating with two-component epoxy, PU-based painting (Polyurethane), hot-dip galvanization according to ASTM A123 standards and especially the Al-Mg spray coating method (at the ratio of 5% Al and 95% Mg) which ensure the anti-corrosion durability of up to 100 years, this method is proved by the salt-spraying test in 6000 hours (8-hour dry-wet cycle) according to ASTM B117
Suitable for after replacement market SMOOTH OPERATION: Stable and smooth operation, good mute effect, practical and durable. The bearing is stable, low noise and long service life. STAINLESS BEARING STEEL MATERIAL: It is made of high quality stainless bearing steel material, rust and corrosion resistant. Product hardness, high precision, can withstand high speed, high load. HIGH PRECISION & HIGH HARDNESS: High precision, high hardness, high speed, high load, applicable for motors, toys, models, instrumentation, power tools, communication equipment, fitness equipment and other fields.

AINiCo is composed primarily of Aluminum Nickel Cobalt and also Copper and Titanium. They are manufactured through either casting or sintering process. Cast AINiCo may be manufactured in complex shapes such as horseshoes not possible with other magnet materials. Sintered AINiCo offer slightly lower magnetic properties but better mechanical characteristics. it can be efficiently magnetized in any direction, and for anisotropic AINiCo magnet, it generally has greater magnetic capacitive in a preferred orientation than isotropic types. AINiCo is hard and brittle, Machining or drilling cannot therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. Advantages of AlNiCo Magnet: 1.Customized designs are available. 2.Max working temperature can be as high as 550�°C. 3.Disadvantage: Br and BH(max)are not as high as rare earth magnet. 4.High energies and relatively low coercivity. 5.High magnetic flux density; low mold charge stable temperature properties; easy to shape. Application of AlNiCo Magnet: *Electronic Ignition Systems *Watt Hour Meters *Medical Instruments *Guitar Pickups *Industrial Motors *Hand Tools *Automatic Control Appliance *Vending Machines
