Folding Self-aligning Ball Bearing Product Features:

It mainly bears radial load and can bear small axial load. The axial displacement of the shaft (housing) is limited to the clearance limit, and has self-aligning performance, allowing normal work under the condition of relatively small internal and peripheral tilts. It is suitable for parts where the support seat hole cannot strictly guarantee coaxiality.

Folding self-aligning ball bearing structure:

Self-aligning ball bearings with dust caps and seals are filled with an appropriate amount of grease during assembly. They should not be heated or cleaned before installation, and need not be relubricated during use. They are suitable for operating temperatures-30 ℃ to + 120 ℃ between. Self-aligning ball bearings are mainly used for precision instruments, low-noise motors, automobiles, motorcycles and general machinery. They are the most widely used bearings in the machinery industry.

Work requirements:

For heavy load, bad working conditions or bearing arrangements with special requirements for sealing, built-in contact sealed spherical roller bearings can be used. The bearing dimensions are exactly the same as non-sealed bearings, which can replace non-sealed bearings in many occasions. The permissible self-aligning angle is 0.5 °, and the working temperature is -20 ℃ ~ 110 ℃. The bearing has been filled with an appropriate amount of lithium-based antirust grease, and grease can also be added according to user requirements. According to the inner ring with or without ribs and the cage used, it can be divided into two basic types: C and CA. The characteristics of C-type bearings are that the inner ring has no ribs and uses steel stamped cages. There are ribs on both sides of the inner ring and a solid car cage is used. This type of bearing is especially suitable for working under heavy or vibration loads. Spherical roller bearings are equipped with drum roller bearings between an inner ring with two raceways and a spherical outer ring.
