Is nylon cage suitable for hydraulic oil pump motor bearings? Learn with Dalan Motor!
Most small and medium-sized rolling bearings have a cage. The main function of the cage is to equidistantly separate the rolling elements and distribute them evenly on the circumference of the raceway to prevent collision and friction between the rolling elements during work; then the hydraulic special oil pump motor Whether it is appropriate to choose nylon cages, the specific Dalan motor editor will talk to you.
After using nylon cage bearings, it has low vibration, low noise, low calorific value and high bearing capacity, which can increase the limit speed and life of the bearing. It has good strength and elasticity, chemical resistance, aging resistance and good dimensional stability. Features. Generally, it can work stably for a long time within the temperature range of -40 ℃ ～ + 80 ℃, and it is compatible with bearing lubricants.
Advantages of nylon cage bearings:
The nylon cage of the bearing, referred to as plastic protection, is a new generation of products that currently replace the iron cage. Compared with the metal cage, it has many advantages:
(1) It is light in weight and improves the flexibility of bearings. If it is used in electrical appliances or power consumption products, it has a great effect on energy saving.
(2) Low noise, is the first choice for manufacturing silent bearings, especially for electrical appliances that require high noise, nylon cage is the first choice.
(3) The service life of the bearing is effectively extended. The friction of the nylon cage against the rolling body is lower than that of the metal cage against the steel ball, which greatly extends the service life of the bearing.
(4) Manufacturing is relatively simple, which greatly improves production efficiency and reduces production costs.
Disadvantages of nylon cage bearings:
(1) Nylon cage bearing can only work at normal temperature, if the temperature is slightly higher, the bearing will be locked due to the plastic deformation of the cage.
(2) The compressive strength of the nylon cage is not as strong as the metal steel plate cage, and the load capacity is relatively low.
(3) Nylon cage bearings cannot be used in environments where they have corrosive effects.
In short, the metal cage of the bearing and the nylon cage have their own advantages and disadvantages. The user should choose to use according to the use requirements when choosing. For example, the use of low-noise electrical appliances should choose the nylon cage bearing, and finally choose it on the motor with temperature load Steel stamping cage bearings.
