6707-ZZ Thin Section Deep Groove Ball Bearing For Precision Robotics & Compact Assemblies | 35×44×5 mm

Engineered for extreme space limitations, the 6704-ZZ is a single row thin-section ball bearing that delivers high-speed capabilities in a remarkably compact form. Featuring dual pressed steel shields (ZZ), this 20x27x4 mm component effectively guards against coarse debris while retaining the premium factory lubricant. Its ultra-lightweight architecture is highly sought after for advanced robotics, micro-motors, and precision instrumentation where minimizing rotational mass is essential.

The 6704-2RS is an ultra-compact, single row ball bearing engineered specifically for constrained spaces where protection against environmental contaminants is an absolute priority. Distinguished by its dual rubber contact seals (2RS), this thin-wall model creates a highly effective barrier against moisture, dust, and abrasive particles while securely retaining its internal lubrication. With its precise 20mm bore, 27mm outer diameter, and slim 4mm profile, the 6704-2RS delivers exceptionally reliable performance for outdoor robotics, fluid-handling devices, and specialized optical gear.

The 6704 is an ultra-lightweight, unsealed single row ball bearing designed for applications where maximum rotational speed and absolute minimum frictional resistance are required. Featuring a classic open architecture, this thin-wall bearing provides direct access to the rolling elements, making it ideal for machinery equipped with continuous oil circulation or oil bath lubrication systems. With its highly compact 20mm bore, 27mm outer diameter, and 4mm width, the 6704 serves as a foundational component for internal, highly protected mechanical assemblies where space is at a premium.

The 6703-ZZ is a specialized thin-wall metric ball bearing engineered for applications where strict weight reduction and limited radial space are primary concerns. Featuring two non-contact steel shields (ZZ), this component effectively blocks external particulates while maintaining minimal rotational friction. With an oversized 17mm bore, a compact 23mm outer diameter, and a narrow 4mm width, it is an optimal choice for hollow shaft designs, robotic joints, and advanced aerospace mechanisms.

The 6703-2RS is a high-performance, extra-light series ball bearing designed for mechanical assemblies that demand a balance between compact dimensions and superior protection. Equipped with dual-lip synthetic rubber seals (2RS), this model excels in shielding the internal raceways against moisture, grit, and lubricant leakage. Its thin-wall profile, featuring a 17mm bore and a 23mm outer diameter, makes it an essential component for outdoor robotics, bicycle hubs, and industrial sensors operating in challenging environments.

The 6703 is a premium open-type thin-section ball bearing designed for high-precision assemblies where external lubrication systems are utilized. By eliminating seals and shields, this model offers the absolute minimum starting torque and rotational resistance, allowing for seamless operation in high-speed oil-bath or oil-mist environments. Its 17mm bore and 23mm outer diameter provide a large inner diameter relative to its slim 4mm width, making it a favorite for hollow-shaft sensors and high-frequency instrumentation.

The 6702-2RS is a high-precision, extra-light series bearing engineered for mechanical assemblies where radial space is extremely limited but environmental protection is mandatory. Outfitted with dual contact rubber seals (2RS), this bearing provides a resilient barrier against fine dust, moisture, and lubricant leakage. With a 15mm bore and a slender 4mm width, it is an essential component for high-performance bicycle hubs, robotic joint actuators, and compact medical rotary devices.

The 6702 is a high-precision open-type thin-section bearing designed for advanced mechanical systems that prioritize ultra-low starting torque and unrestricted lubrication access. By omitting integrated seals or shields, this model achieves the lowest possible rotational friction, making it an ideal candidate for high-speed oil-bath environments and sensitive measuring instruments. With a 15mm bore and a slim 4mm profile, the 6702 serves as a critical rotational support for hollow-shaft encoders, robotic joints, and aerospace-grade telemetry systems.
