Product Description

📦 Product Introduction

The 6801-OPEN Deep Groove Ball Bearing is a precision-engineered thin-section bearing designed for applications requiring high rotational speeds and minimal friction. With a compact envelope of 12mm bore * 21mm OD * 5mm width, this bearing is an ideal solution for space-constrained environments.

⚡ Key Advantage — Open Design: The unsealed (OPEN) configuration allows direct oil lubrication and superior heat dissipation, making it the preferred choice for high-speed electric motor applications where the bearing operates within a lubricated housing or oil-bath system. This design achieves up to 30,000 RPM under oil lubrication — significantly outperforming sealed variants in sustained high-speed duty cycles.

Manufactured from premium GCr15 chrome steel (equivalent to AISI 52100 / 100Cr6) and precision-ground to ABEC-3 (P6) tolerance standards, the 6801-OPEN ensures consistent performance with low vibration and extended service life. Each bearing undergoes 100% noise and dimensional inspection before shipment.

⭐ Product Features

High-Speed Performance

Open design supports up to 30,000 RPM with oil lubrication, ideal for high-RPM motor spindles and dental handpieces.

Premium Chrome Steel

GCr15 / AISI 52100 bearing steel with through-hardened raceways (HRC 60-64) for exceptional wear resistance and fatigue life.

ABEC-3 Precision

P6 tolerance class with controlled radial runout (≤5μm) and low noise rating (Z2/V2 minimum), ensuring smooth, quiet operation.

Easy Lubrication

Open configuration enables direct grease packing or integration into oil-circulation systems for optimal maintenance routines.

Thin-Section Compact

Ultra-slim profile (12*21*5mm) saves space and weight in miniature motor assemblies and portable devices.

100% Inspected

Every bearing passes noise testing, dimensional measurement, and visual inspection before packaging. ISO 9001:2015 certified factory.

🔧 Application Scenarios

Electric Motors

Miniature DC/BLDC motors, servo motors, stepper motors requiring high-speed open bearings in oil-lubricated housings.

Power Tools

Rotary tools, die grinders, and high-RPM handheld tools where heat dissipation through open lubrication is critical.

Dental Handpieces

High-speed dental turbines and contra-angle handpieces operating at 30,000–40,000 RPM under oil-mist lubrication.

Industrial Pumps

Circulation pumps and vacuum pumps with integrated oil-bath lubrication systems for continuous-duty operation.

Robotics

Lightweight robotic joint actuators and precision motion control modules requiring compact thin-section bearings.

Office Automation

Printer rollers, copier drum assemblies, and high-speed scanner mechanisms in precision OA equipment.
