⚙️Product Description:

Need to anchor a large 25mm rotating axis within an incredibly tight radial envelope? Our 6705ZZ and 6705-2RS Thin Section Deep Groove Ball Bearings (25x32x4mm) deliver the perfect engineering answer. Featuring a uniquely wide bore relative to its remarkably slim 4mm width, this micro-profile bearing is specifically optimized for hollow-shaft applications requiring expansive internal clearance for wiring or slip rings. As an agile global B2B bearing trader, we provide adaptable procurement models: maximize your cost-efficiency with our proprietary RMO brand factory-direct supply, or utilize our global network to source premium international legacy brands to align with your rigid technical blueprints.

6705 thin bearing

⚙️Product Features:

  • Large Bore with Ultra-Slim Profile: Designed with a 25mm inner diameter and 32mm outer diameter, creating an ultra-narrow 3.5mm cross-sectional height that effortlessly solves space-critical design bottlenecks.
  • Versatile Shielding Systems: Available as 6705ZZ (Dual Metal Shields) for low-torque, ultra-high-speed operations, or 6705-2RS (Dual Rubber Seals) for superior defense against fine dust and moisture intrusion.
  • Premium GCr15 Chrome Steel: Forged from high-carbon chromium bearing steel, ensuring excellent rolling fatigue life, dimensional stability, and high load-bearing performance under continuous rotation.
  • Minimized Rotational Inertia: The skeletonized, low-mass design significantly reduces the starting and running torque of your mechanical assemblies, heavily conserving energy in battery-operated motor drives.
  • Streamlined Multi-Brand Sourcing: Seamlessly choose between wholesale factory-direct orders of our RMO brand or direct trading channels for specific top-tier global brands to suit diverse market tiers.

⚙️Product Application:

Striking an exceptional balance between an expanded internal diameter and a miniature cross-section, the 6705 series is heavily specified for:

  • Industrial automation turntables, rotary tables, and hollow-shaft collaborative robot (cobot) joints.
  • Precision optical instruments, laser scanning modules, and large-scale camera gimbal rings.
  • Specialized medical imaging gear, laboratory diagnostic arrays, and fluid control hardware.
  • High-performance E-bike hub motors, aerospace actuator components, and micro-stepper drives.
  • International B2B component distributors and mechanical OEMs searching for non-standard, lightweight precision bearings.

⚙️Precautions:

1. Keep clean2. Use with caution3. appropriate tool4. Hot-loading5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.Strong impact during use can easily cause scratches and indentations.Avoid replacing existing tools, and use appropriate tools.Bearings are precision parts, so hot installation is recommended.Sweat on your hands during operation will cause rust, so it is best to wear gloves.
