Product Overview

The S6700 is a single-row deep groove ball bearing made from AISI 440C stainless steel. This martensitic stainless steel provides excellent corrosion resistance and high hardness, reaching 58–62 HRC.

Moreover, the S6700 performs well in environments with moisture, salinity, or mild chemicals. Standard chrome steel bearings may quickly degrade in these conditions, while stainless steel construction provides longer-lasting performance.

Core Advantages

Superior Corrosion Resistance

The stainless steel structure offers strong protection against moisture, saltwater, and mild chemicals. Therefore, the S6700 is ideal for marine equipment, food processing machinery, and outdoor applications.

It helps prevent rust and premature bearing failure. As a result, equipment can maintain stable operation even in challenging environments.

Ultra-Compact Footprint

The S6700 features compact dimensions of 10×15×4 mm. With a weight of only 1.9 grams, it is one of the most space-efficient bearings available.

Its ultra-thin design supports equipment miniaturization. At the same time, it maintains reliable bearing performance for precision applications.

High Precision and Smooth Operation

The S6700 delivers accurate rotation and smooth movement. Its precision manufacturing helps reduce friction and improves operational stability.

This makes it suitable for applications that require consistent motion and low vibration.

Versatile Sealing Options

The S6700 is available in open, shielded (ZZ), and sealed (2RS) versions. Therefore, users can select the right configuration according to different operating conditions.

Open versions work well with clean and oil-lubricated environments. Meanwhile, sealed and shielded versions provide better protection against dust, moisture, and contaminants.

Pre-Lubricated and Ready to Install

Shielded and sealed models come with factory-applied high-quality grease. They are ready for immediate installation without additional packing or lubrication.

Simply press the bearing into the assembly, and it can start operating.

Food-Grade Compliance

Food-grade grease options are available for applications requiring strict hygiene standards.

Therefore, the S6700 can support food processing, beverage, and pharmaceutical equipment where cleanliness and safety are important.

Long Service Life in Demanding Environments

The combination of stainless steel material, precision manufacturing, and effective sealing improves durability.

As a result, the S6700 provides extended service life in demanding operating conditions.

Applications

The S6700 stainless steel bearing supports many industries and precision equipment applications.

Food Processing and Beverage Equipment

The bearing is suitable for conveyors, filling machines, bottling lines, mixers, and packaging equipment.

Furthermore, its stainless steel construction and food-grade grease option help meet hygiene requirements in washdown environments.

Marine and Offshore Equipment

The S6700 works well in boat steering systems, deck machinery, underwater cameras, and desalination equipment.

Its corrosion resistance helps protect against constant saltwater exposure.

Medical and Pharmaceutical Devices

The bearing supports diagnostic instruments, laboratory centrifuges, surgical tools, and cleanroom equipment.

It provides reliable motion control while reducing contamination risks.

3D Printers and Additive Manufacturing

The S6700 is commonly used in filament drive systems, print head guide rails, and axis movement mechanisms.

Its smooth rotation helps achieve accurate and consistent printing results.

Robotics and Automation

Small robot joints, pick-and-place actuators, and automated assembly systems benefit from the bearing’s compact size and precision.

In addition, its stainless steel construction improves reliability in demanding automation environments.

Remote Control (RC) Models and Drones

The S6700 supports motors, gearboxes, and rotor assemblies in RC vehicles, helicopters, and UAV systems.

Its lightweight structure helps reduce overall equipment weight.

Small Electric Motors and Micro Gearboxes

The bearing is suitable for stepper motors, servo motors, cooling fans, and miniature gear drives.

It provides reliable performance where installation space is limited.
