Any KOYO bearings that are not properly lubricated; failure to avoid early failure; because KOYO bearings are not easy to assemble and disassemble the rubber in the hub; and innately apply the incorrect grease; and do not replace the grease in later use; It may not be replaced in time after the carbonization of the grease has become contaminated. It is difficult for your hub to meet the long life and excellent lubrication.
The bicycles used in bicycles nowadays encounter the small standard KOYO bearings that are deep groove balls; such as 609; 6000; 6001; 6200; these are industrially used for the stator and rotor of small-scale motors. Lin; and such a small Palin is generally pre-installed at the time of purchase is a low-viscosity; high-lubricity broad-spectrum grease.
In the past, we have used many faulty purchases and used such expensive greases; for example, SKF's LGMT-2, which we purchased at the time, constitutes lithium-based grease; this is a low-torque, low-conflict small motor. Lubricating oil; also used in most small skf Palin; the price is still very expensive; the price of 200 grams of packaging is up to 60 yuan; but the viscosity of this oil is only 110; for high load; extreme pressure The ability to reciprocate is poor; depending on the use of the bicycle shaft; this should be a low speed; high extreme pressure (because a lot of pressure will only be concentrated on a few fine Palin; and the impact will occur more Great pressure); So we later selected SKF's LGEP-2 to form lithium base grease; this is expensive (155 yuan); however, its viscosity reaches 200; high load; high waterproof; high rust resistance; Although it is not as good as LGMT-2 in the low torque conflict indicator, it is completely suitable for the front and rear axles and the front bowl of the bicycle (today we have some old hubs; if the rm40 correction is LGEP-2 lubrication).
2), the reason for KOYO imported bearings early damage is not properly installed another damage up to 16% of the reason; this is not properly installed; and faulty or violent loading method; make those Palin appear when loading 2. There has been a crack on the surface of the lubricated bowl.
In order to make the Palin card tight axis; avoid the occurrence of the bushing conflict appearance (this kind of appearance will occur when the high-speed transformation of the machine is high; the formation of lubricating oil burns and even causes the heat to rise and die; form a stop); so KOYO bearings The inner and outer bowls (also known as KOYO imported bearing boxes in the industry) use a "overweight" appearance; in a nutshell, the shaft is larger than the inner one; perhaps the outer bowl is larger than the load; this kind of interference is very large The strength of the force can be loaded; and such loading requires a great effort to strike the Palin; this will form the damage of the Palin in the process of tapping; therefore, the industrial large KOYO bearings are generally heated; hydraulic top Into the way.
Bicycles use glued deep groove ball bearings; such KOYO bearings are most afraid of knocking (the needles of Palin and Dapelin are slightly more resistant to percussion); and they do not use the heating method; Because the bicycle Palin's over-profit is very good. 踔寥缜 ç…å—” ç…å—” ç…å—” ç…å—” ç›® æ‚ æ‚ æ‚ æ‚ æ‚ æ‚ å‡° 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 凰 é‚£ é‚£ é‚£ é‚£ é‚£ é‚£ é‚£Shallow F downhill, ç »å¦« ç »å¦« 褂 褂 擦 擦 擦 擦 擦 擦 擦 擦 擦 褂 褂 褂 褂 褂 褂 褂 褂

ABS Toilet Flush Panel features:
Beautiful Appearance: ABS flush panels offer the advantage of customizable designs and colors to suit the customer's preferences and the overall aesthetic of the bathroom. This allows for a visually appealing Toilet Tank panel.
Strong Durability: ABS material is known for its excellent durability. It can withstand prolonged use without deforming or losing its original shape. Additionally, ABS does not easily discolor over time, ensuring that the flush panel maintains its attractive appearance.
Easy to Clean: The smooth surface of ABS material makes it easy to clean. Regular wiping or cleaning with a soft cloth or sponge can effectively remove dirt, stains, or residue, keeping the toilet flush panel looking clean and well-maintained.
Easy Installation: ABS toilet push buttons are lightweight, which simplifies the installation process. They can be easily installed onto the water tank without the need for complex tools or equipment. This convenience saves time and effort during the installation process.
Strong Corrosion Resistance: ABS water tank panels exhibit excellent resistance to corrosion. They are not susceptible to damage from chemical substances or water erosion. This quality ensures the longevity and reliability of the flush panel, even in environments where exposure to water or cleaning agents is common.
In summary, ABS toilet tank panels offer a combination of aesthetic appeal, durability, ease of cleaning, and convenient installation. These features make ABS an excellent choice of material for toilet tank panels.
