Eliminate Downtime with Reliable Deep Groove Ball Bearing 628/9-Z and 628/9-2Z

Equipment failures due to substandard bearings cost manufacturers countless hours of production and unexpected repair expenses. Many face challenges with inconsistent quality from unknown suppliers or struggle to source small batches for emergency maintenance. When precision machinery like CNC spindles or printing equipment stops working, every minute of downtime impacts your bottom line.

Precision Engineered 9x17x5mm Bearings for Critical Applications

Our Deep Groove Ball Bearing 628/9-Z and 628/9-2Z address these pain points with reliable performance and flexible supply. As a professional bearing manufacturer with over 15 years of experience, we produce these 9x17x5mm bearings to meet P0-P4 precision grades and Z2-Z4 noise standards, ensuring compatibility with high-precision machinery. Whether you need single-shielded (Z) or double-shielded (2Z) variants, our production capacity of 1,000,000 units annually guarantees stable supply for both small repairs and bulk production needs.

Optimal Performance in Demanding Precision Machinery

These radial deep groove ball bearings excel in applications requiring smooth rotation and minimal noise, such as electric motor shafts, precision gearboxes, and small-scale industrial conveyors. The 9mm bore diameter, 17mm outer diameter, and 5mm width make them ideal for compact machinery where space is limited. The single-row design ensures efficient radial load handling, while shielded options provide protection against dust and contaminants in manufacturing environments—critical for extending bearing service life in textile or packaging equipment.

Key Technical Features That Ensure Long-Term Reliability

Crafted from high-grade bearing steel, these bearings deliver consistent performance under varying operating conditions. The unseparated design enhances structural integrity, preventing component disassembly during high-speed rotation—a common issue with lower-quality alternatives. Shielded variants (Z/2Z) reduce lubricant leakage and contamination ingress, lowering maintenance requirements for equipment like CNC machine tool spindles. Our strict quality control processes, including dimensional inspection and noise testing, ensure each bearing meets ISO industrial standards, directly contributing to reduced equipment vibration and extended service intervals.

Avoid Hidden Costs: Why Authentic Bearings Matter

Choosing non-genuine bearings may save upfront costs but often leads to frequent replacements, unplanned downtime, and potential damage to expensive machinery. A single bearing failure in a printing press can halt production lines, resulting in losses that far exceed the initial savings. Our bearings, produced in compliance with ISO 9001:2015 standards, undergo full-process quality supervision—from raw material inspection to finished product testing. This commitment to quality translates to predictable performance and lower total cost of ownership, especially for manufacturers relying on precision equipment.
