Requirements for Bearings in Linear Actuators (Push Rod Motor).
Linear actuators typically use two sets of bearings with the
following requirements:
1.Excellent Dust Protection:
The bearings must effectively prevent external dust from entering
the internal components, ensuring long-term performance and
reliability.
2.Wide Operating Temperature Range:
The bearings should function reliably within a temperature range of
-50°C to 150°C, ensuring they can handle both extremely cold and
hot environments.
3.Low Noise Operation:
The bearings must operate quietly, minimizing noise levels during
operation, which is crucial for maintaining a pleasant working
environment.
4.Service Life:
Designed for longevity, these bearings should have a long service
life with minimal maintenance requirements, enhancing overall
system reliability and reducing downtime.
What's the Performance Features of 6903 ZZ Bearings in Linear
Actuators(Push Rod Motor)?
The 6903 ZZ bearing is well-suited for linear actuators (push rod
motors), offering excellent dust protection with metal shields that
prevent contamination, ensuring long-term performance. It operates
reliably across a wide temperature range of -50°C to 150°C, making
it adaptable to extreme environments. The bearing provides low
noise operation, crucial for maintaining a quiet working
environment, and is designed for longevity with minimal
maintenance, enhancing system reliability and reducing downtime.
Its robust features make it an ideal choice for the demanding
conditions of linear actuator applications.
What's the Applications of the 6903 ZZ Bearing?
The 6903 ZZ bearing, with metal shields on both sides, is designed
for compact and quiet applications that need protection from dust
and contaminants. It is commonly used in small home appliances like
blenders and coffee grinders, consumer electronics such as DVD
players and electric toothbrushes, office equipment including
printers and scanners, and small power tools like screwdrivers and
mini grinders. This bearing also supports automotive parts like
window regulators and electric mirrors, as well as medical devices
and sports equipment. Its robust design ensures reliable,
low-maintenance performance in various small mechanical systems
where precision and durability are important.
