2、 Characteristics
Structural Design
Full needle roller design: enhances radial load-bearing capacity, suitable for high load scenarios.
Equipped with eccentric sleeve (E-type): supports installation position adjustment to enhance adaptability.
Double lip seal (PP type): Plastic sealing rings are installed on both sides to effectively prevent dust and dirt.
Performance optimization
High load-bearing capacity: The thicker outer ring and optimized raceway shape can withstand high radial loads and slight axial forces.
Long lifespan: Adopting X-life design and material improvement, the basic rated lifespan is increased by 30%, while reducing the stress on the supporting track.
Anti deflection ability: The coronal outer surface (R=500mm or INA optimized contour) avoids edge stress caused by tilting.
3、 Application
Typical scenario
Cam transmission system: suitable for transmission mechanisms that require high precision and reliability.
Guide rail system: such as machine tool guide rails and automation equipment guide rails, supporting smooth linear motion.
Conveyor equipment: used in scenarios such as drum and chain transmission, suitable for frequent start stop and high load requirements.
