6900RS 10x22x6mm Bicycle Bearing 10Pcs ABEC-7 Chrome Steel Double Sealed 6900-2RS Bicycle Wheel Hub Pivot Repair Replacement

1. High-Grade Bearing Steel Construction for Superior Durability
Engineered from high-carbon chromium bearing steel (GCr15), these 2RS sealed bearings offer outstanding
hardness, exceptional wear resistance, and robust structural strength. The precision-hardened steel material
maintains dimensional stability under heavy radial and combined loads, delivering extended service life and
reliable performance across continuous industrial and mechanical operating conditions.
2. ABEC-7 Precision Grade for Ultra-Smooth Rotational Performance
Manufactured to strict ABEC-7 tolerance standards, these bearings feature finely honed raceways and tight
dimensional control that minimize friction, reduce operational noise, and ensure remarkably smooth rotation.
The high-precision geometry guarantees consistent concentricity and running accuracy, making them an
excellent choice for applications demanding precise motion control and quiet, vibration-free operation at
varying speeds.
3. Double-Sided Rubber Seals (2RS) for Enhanced Contamination Protection
Fitted with two contact-type nitrile rubber seals (2RS designation) on both sides, these bearings provide
superior sealing performance against dust, dirt, and other environmental contaminants. The lip-seal design
effectively prevents lubricant leakage while blocking outside particles from entering the bearing interior,
making them ideal for heavily dusty working environments where metal shields alone offer insufficient
protection.
4. Factory Pre-Lubricated with Premium Grease for Immediate Deployment
Each 2RS bearing comes pre-filled with high-quality lithium-based grease, optimized for balanced wear
protection and temperature resistance. The sealed configuration retains lubricant effectively, extends
relubrication intervals, and ensures consistent friction reduction and corrosion protection from the
moment of installation — no additional lubrication required before use.
5. Broad Compatibility for Diverse Industrial and Mechanical Uses
Combining durable bearing steel construction, ABEC-7 precision, and reliable double rubber sealing,
these versatile bearings excel across a wide range of applications including electric motors, garden
tools, household appliances, conveyor systems, automotive components, agricultural machinery,
outdoor power equipment, and general mechanical assemblies exposed to varying environmental
conditions.
