Product Overview
Deep Groove Ball Bearings are iconic rolling bearing products favored globally for their simple structure, outstanding performance, and versatile applications in various industries.
⚙️
Dual Load-Bearing Capacity
Adopts a single-row deep-groove ball design, primarily bearing radial loads. Can endure substantial axial and composite loads when internal clearance is increased.
⚡
High-Efficiency Operation
Circular arc raceways minimize friction, enabling extremely high rotational speeds (e.g., up to 31,000 r/min with oil lubrication).
🌡️
Temperature Resilient
Works stably within a range of -30°C to +120°C, adapting to most demanding working conditions.
Technological Advancement
The new "HPS" series optimizes contact geometry, reducing friction by 35% and noise by 50% while extending grease life. High-quality materials like SUJ2 special steel guarantee wear resistance and operational accuracy.

Frequently Asked Questions
Q1: What are the primary applications for these bearings?
A: They are widely used in precision instruments, low-noise motors, automobile transmissions, engines, CNC machines, and general machinery like pumps and compressors.
Q2: Can these bearings handle both radial and axial loads?
A: Yes, while primarily designed for radial loads, increasing the internal clearance allows them to handle significant axial and composite loads.
Q3: Do the sealed variants require maintenance?
A: No, sealed or shielded variants are pre-filled with high-quality grease at the factory and typically require no additional lubrication during their service life.
Q4: What makes the HPS series better than standard bearings?
A: The HPS series features optimized raceway geometry that reduces internal friction by 35% and noise levels by 50%, significantly extending the grease life.
Q5: What is the operating temperature range?
A: These bearings are designed to operate reliably within a temperature range of -30°C to +120°C.
Q6: What materials are used in their construction?
A: They use high-quality materials such as SUJ2 special steel combined with advanced precision machining processes for maximum wear resistance.
