62 Series Deep Groove Ball Bearings
Product Overview
The 62 Series Deep Groove Ball Bearings are the most widely used series within the deep groove ball bearing family. Offering a balanced combination of load capacity, speed capability, and dimensional versatility, the 62 Series serves as the industry standard for general-purpose applications across a broad range of industries.
With a larger cross-section compared to the 60 Series, the 62 Series accommodates bigger rolling elements, resulting in higher dynamic and static load ratings while maintaining reliable performance at moderate to high speeds. Available in precision grades from P0 to P5 to meet the requirements of both standard industrial and higher-precision applications.
Sealing options include open type, single and double-sided metal shields (Z/ZZ), non-contact seals (RZ/2RZ), contact seals (RS/2RS), and mid-contact seals (RS1/2RS1), allowing flexible selection based on the specific requirements for dust protection, moisture resistance, and friction loss in different operating environments.

Applications
The 62 Series is one of the most broadly applied bearing series across industries. In electric motors and generators, it supports both radial and moderate axial loads at sustained operating speeds, making it a standard choice for motor manufacturers worldwide. In pumps and compressors, the series delivers reliable performance under continuous radial loading in demanding environments where consistent uptime is critical.
In gearboxes and power transmission systems, the 62 Series handles the combined radial and axial loads generated by gear forces, providing stable support across a wide range of shaft sizes. Conveyor and material handling equipment benefit from its high load capacity and long service life under continuous duty cycles.
The agricultural machinery sector relies heavily on the 62 Series for its durability and resistance to contamination when used in sealed configurations, covering applications from tractors and harvesters to irrigation pumps and grain handling equipment. In the automotive industry, it is widely used in alternators, cooling fans, water pumps, and auxiliary drive systems.
Beyond heavy industry, the 62 Series is also found in HVAC equipment, textile machinery, packaging lines, and light industrial equipment wherever a dependable, cost-effective, and broadly available bearing solution is required.

FAQs
What loads can deep groove ball bearings handle?
Deep groove ball bearings are primarily designed for radial loads, but they can also handle moderate axial (thrust) loads in both directions. They are not suitable for heavy axial loads or combined shock loads. In those cases, angular contact or tapered roller bearings are preferred.
How do I select the right bearing size for my application?
Selection should be based on bore diameter (shaft size), required load capacity (dynamic rating C and static rating C0), operating speed compared with the bearing limiting speed, available space (outer diameter and width), and required precision grade from P0 to P2. Always apply a safety factor and verify that the calculated L10 service life meets your requirements.
What is the difference between open, shielded (ZZ), and sealed (2RS) bearings?
Open: No built-in protection, requires external sealing, and is suitable for clean environments or oil bath lubrication.
ZZ metal shields: Protect against dust and debris with low friction, making them suitable for high-speed applications, but they are not waterproof.
2RS rubber seals: Provide strong protection against dust and moisture. They are pre-greased and ideal for contaminated environments, but generate slightly more friction.
How often should I lubricate or replace the grease?
For general industrial use, grease should be replenished or replaced every 3,000 to 10,000 operating hours depending on speed, temperature, and environmental conditions. Bearings running above 70 C or in contaminated environments require shorter intervals. Sealed 2RS bearings are pre-greased for life and do not require re-lubrication.
What are the common causes of premature bearing failure?
The most frequent causes include inadequate or improper lubrication, contamination by dirt, dust, or moisture, incorrect installation, misalignment, excessive force during fitting, overloading beyond the rated capacity, improper shaft or housing fits, and fatigue at the end of normal service life.
How is the rated service life (L10) of a bearing calculated?
The basic L10 life is calculated as L10 = (C / P)^3 x 10^6 revolutions, where C is the dynamic load rating in kN and P is the equivalent dynamic bearing load in kN. It represents the number of revolutions that 90% of identical bearings will complete without fatigue failure. In practice, ISO 281 modified life calculations also apply correction factors for lubrication, contamination, material, and reliability.
