Thin-film chrome-plated and anti-friction bearings are attributed to TIMKEN's high-performance bearings; they all have their own special functions.
1. TIMKEN thin-film chrome-plated dense-plated bearing TIMKEN thin-film chrome-plated dense-plated bearing is specially described; it is mainly used to improve the function of bearings in severe corrosive environments. The thin-film chrome-plated dense-plated bearing can supply rust-resistant products that are not required by the standard bearings. And the function of etching.
The coating of the thin-film chrome-plated bearing is also a special depiction; it has a strictly controlled spherical layout; thus the bearing has a higher strength and hardness. This depiction can reduce the cost of the bearing; reduce the strike time of the equipment; The cost of protecting and replacing parts.
Second, TIMKEN anti-friction bearings TIMKEN anti-friction bearings are specifically designed for the use of wind turbines; the first is to reduce the wear problems affecting the bearing life; including micro-pitting and wind power gearboxes appearing on the spindle spherical roller bearings The problems of micropitting, scratching and brittle shedding on the bearing. The L10 life of the anti-wear bearing is 3.5 times longer than that of the normal spindle and gearbox bearing.
TIMKEN wind power anti-friction bearings have the following characteristics: the internal development of wear-resistant coatings and bearing materials; can be used to resist the abrasion, micropitting and fretting wear caused by the adhesive wear mechanism.
The roller polishes the ferrule raceway; the Ra is lowered (outside finish); the cymbal is increased; the tumbling moment is reduced; the power is improved.
The common coating can provide useful protection against adhesive wear during a temporary smooth oil loss period.
The roller is specially depicted to eliminate debris on the raceway; to reduce the surface roughness of the ferrule raceway,

Application: HEDP is used as scale inhibitor, deflocculant, sequestrant, water stabilizer in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc under condition of high temperature and high pH value. HEDP is also used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent.
