Dentail

Key Features

Ultra-lightweight Construction
- Advanced wall-thinning technology reduces weight by 40-60% compared to conventional bearings
- Materials: Vacuum-degassed bearing steel (SUJ2) or SiC ceramic for HRC60+ hardness and 10^7+ fatigue cycles
ISO Metric Compliance
- Full adherence to ISO 15:2011 dimensional standards with IT5-class tolerance control
- 72/73/74 series compatible with global OEM replacement parts
Modular Sealing Solutions
- Available in open (-RS), double-lip (-2RS), and labyrinth (-Z) configurations
- IP65-rated integrated shields for environments with ≤10mg/m³ dust concentration

Application

The bearings can be used in the following industries

Semiconductor: Wafer stages in lithography tools (radial runout ≤2μm)
Aerospace: Gyroscope supports in inertial navigation systems (-55℃~+125℃ operation)
Medical: PET-CT gantries (service life ≥20,000 hours)
EVs: Wheel hub motor drives (50g vibration resistance)
