The importance of bearing casters

Casters application is very broad, almost any design industries. According to the needs of different industries, people are constantly being invented all kinds of casters in the world there are about 150,000 kinds of different casters used in various industries.
Caster bearings is very important for the caster. Castors with bearings have a good variety, and without it, casters will lose its value. We therefore recommend that the backing bearings should be desirable for the respective applications, and to ensure the necessary safety margin left. In addition to the tread, the wheel outside diameter and swivel bearing, the wheel bearings determine the only movable casters, and even the quality of the caster only.
For different use of the environment, have different requirements: the factory with a different firm with casters casters, tool cart with casters Unlike hospital bed casters with lightweight, shopping carts with casters requirements certainly completely different from those factories for transporting heavy loads in those casters. Generally, there are four bearings:
1, Patel spiritual bearings: Patel Spirit is the special engineering plastics, suitable for wet and corrosive areas, turning flexibility in general, greater resistance.
2, roller bearings: Heat-treated roller bearings can carry heavier loads, turning flexibility in general.
3, ball bearings: high quality made ​​of bearing steel ball bearings can carry heavier loads, for applications that require rotation flexibility and serenity of the occasion.
4, plane bearings: suitable for high and ultra-high load and high speed applications.crankshaft is integral with the overall steel forging. This is characterized by the crankshaft main journal, the crank and connecting rod journal is made a whole. The front shaft end fitted with two belt groove V-belt drive, drag, directly or indirectly, fans, pumps and charger pulley. Rear crankshaft with six screws through the flange connections and tighten flywheel with two cylindrical pin positioning. In the end face of the flywheel with 12 chrome uniform mending holes for mounting couplings and other power output device, start with the flywheel ring gear sleeve surface.
As the spindle neck structure is different, the first gear bearing the same 1,3,5, 2,4,6 same block, 7th gear bearing specific, and each block has hole tile, sheet pile for safety in the 7th gear bearing cover , thin-walled aluminum alloy main bearing bushing, upper and lower watts watts with the main bearing bolts tightened, there are tiles on the hole and the tank, and with the hole in the spindle neck interlinked, lubricating oil from the hole circulate to forced lubrication main bearings and connecting rod journal friction surface friction surfaces. After assembling the crankshaft flywheel assembly, turn the hand crank on the flywheel side should be very flexible.
