JRZC self-aligning ball bearings feature a double-row ball design with spherical raceways, providing excellent self-alignment to compensate
for misalignment from shaft bending or installation errors. They mainly support radial loads with limited axial loads in both directions,
offering low friction, low noise, high speed capability, and long service life. Widely used in motors, fans, textile, agricultural, conveying,
and light industrial equipment.
With 20+ years of manufacturing experience, JRZC delivers reliable self-aligning ball bearings using premium materials, advanced
heat treatment, and strict quality control. We provide OEM/ODM solutions, competitive factory pricing, and global delivery,
making us your trusted bearing partner.

Q1: What applications are self-aligning ball bearings primarily used for?
A: They are widely used in applications such as electric motors, fans, textile machinery, agricultural machinery, conveying equipment, and light industrial machinery where shaft misalignment or installation errors exist.
Q2: What types of loads can self-aligning ball bearings withstand?
A: They primarily withstand radial loads and can also withstand a certain amount of bidirectional axial load, suitable for medium to light load conditions.
Q3: What are the advantages compared to ordinary deep groove ball bearings?
A: JRZC self-aligning ball bearings have self-aligning capabilities, compensating for misalignment, reducing vibration and noise, and improving equipment operating stability and service life.
Q4: Are different clearance and accuracy grades available?
A: Yes, C0, C3, C4 clearance grades and customer-specified accuracy requirements are available.
Q5: Do you support OEM/ODM customization?
A: Yes. JRZC can provide customized services for dimensions, structure, cage type, sealing form, marking, and packaging.
Q6: Can the bearings be pre-filled with grease?
A: Yes. High-temperature grease, low-noise grease, or long-life grease can be pre-filled according to customer requirements.
Q7: What is the service life of JRZC self-aligning ball bearings?
A: Using high-quality bearing steel, advanced heat treatment processes, and strict quality control, they can achieve long-life and stable operation under correct installation and lubrication conditions.
