Single row deep groove ball bearings have a wide variety of different basic standard designs due its different sealing design. The basic designs are shown as the follows.

For manufacturing and economic reason

some of the basic open design bearings

could have grooves in their outer rings,

enable either seals or shields to be fitted.

a open design

b open design with grooves in the outer ring

c bearing with one shield, suffix Z

d bearing with two shields, suffix .2Z

e bearing with one RS seal, suffix RS

F bearing with two RS seals, suffix .2RS

g bearing with one RSR seal, suffix RSR

h bearing with two RSR seals, suffix .2RSR

I bearing with one LFS seal, suffix LFS

J bearing with two LFS seals, suffix .2LFS.
Single row deep groove ball bearings have a very limited ability to accommodate misalignments. Under normal applications conditions, misalignments may not exceed 10 angular minutes maximum from their centre position.It must be considered, however, that bearing which runs misaligned are subjected to considerable additional force that will shorten their service life and generate high running noise.
DHK single deep groove ball bearings are normally fitted with pressed cages as standard.For large bearings, usually have machined solid brass cages as standard (suffix M).

DHK single row deep groove ball bearings are produced to normal tolerance class (PN) asstandard.

On order of customer request, DHK can provide higher dimension and geometrical accuracy precision tolerance class.

DHK single row deep groove ball bearings are produced with normal internal clearance group (CN) as standard.

DHK can provide bearings with other internal clearance group or special clearance according to customer request.

Values of the different internal clearance groups of single and double row deep groove ball bearings are listed in the tables below.

These values are conformity to standard GB/T4604-1991 and ISO 5753-1991.

1. Dynamic Load Capacity (Cr) and Static Load Capacity (Cor)

Series 60 single-row deep groove ball bearings are engineered to excel under dynamic conditions, showcasing an impressive dynamic load capacity (Cr) of 4.55. This parameter is fundamental in assessing the bearing's ability to withstand fluctuating loads encountered during operation, particularly in high-speed applications. The dynamic load capacity of Series 60 bearings signifies their resilience against forces exerted during rotation, acceleration, and deceleration cycles. Whether in automotive transmissions, conveyor systems, or precision machinery, these bearings ensure consistent performance even when subjected to varying operational demands. What sets Series 60 bearings apart is their ability to maintain structural integrity and operational stability under dynamic loads, minimizing the risk of premature wear, fatigue, or failure. This attribute is crucial for industries where reliability and uptime are critical metrics, such as aerospace, manufacturing, and transportation. Complementing the impressive dynamic load capacity of Series 60 bearings is their robust static load capacity (Cor) of 1.96. While dynamic loads fluctuate during operation, static loads exert constant pressure on the bearings, making this parameter essential for applications where stationary or low-speed conditions prevail. The static load capacity of Series 60 bearings reflects their ability to support heavy loads without deformation or damage, ensuring stability and reliability over extended periods of inactivity. In equipment such as heavy machinery, stationary power generators, or structural components, where static loads predominate, these bearings provide critical support and longevity. Series 60 bearings' high static load capacity is a testament to their superior design, precision manufacturing, and use of premium materials.

2. Application Versatility

The versatility of Series 60 single-row deep groove ball bearings extends across a broad spectrum of industries and applications, making them indispensable components in various systems and machinery. In automotive and transportation, Series 60 bearings support essential components such as wheel hubs, transmissions, and steering systems, delivering smooth operation, low friction, and enhanced fuel efficiency. Their reliability under dynamic loads ensures optimal performance in vehicles ranging from passenger cars to heavy-duty trucks and railway systems. In manufacturing and automation, Series 60 bearings find application in conveyor systems, robotic arms, and machining equipment, where their precision engineering and high load capacity contribute to seamless operation, precision motion control, and improved productivity. Their ability to withstand both dynamic and static loads makes them ideal for continuous production environments. Series 60 bearings play a vital role in power generation, HVAC systems, and industrial pumps, where they support rotating shafts, fan assemblies, and drive mechanisms. Their versatility extends to agricultural machinery, where they endure the demanding conditions of tillage, harvesting, and irrigation equipment, ensuring reliable performance season after season.
