Product Description

📦 Product Introduction

The 6801-2RS Deep Groove Ball Bearing is the ultimate sealed solution featuring dual NBR rubber contact seals (2RS type) for maximum protection in harsh and contaminated environments. With a compact envelope of 12mm bore * 21mm OD * 5mm width, this bearing offers the highest level of sealing integrity in the 6801 series, making it the go-to choice for applications exposed to moisture, fine dust, mud, and chemical splashes.

💧 Key Advantage — Rubber Seal Protection: The 2RS configuration uses two NBR (Nitrile Butadiene Rubber) contact seals that create a tight labyrinth barrier against moisture, fine particles, and contaminants. Unlike metal shields, rubber seals provide positive contact sealing, preventing lubricant leakage and blocking water ingress — making this bearing suitable for outdoor, washdown, and wet environment applications. Factory pre-lubricated with water-resistant grease, the 6801-2RS delivers maintenance-free reliability in the toughest conditions.

Manufactured from GCr15 chrome steel (AISI 52100 equivalent) and precision-ground to ABEC-3 (P6) tolerance standards, each bearing undergoes 100% inspection before shipment. The 6801-2RS is the premium choice for engineers who demand maximum sealing performance and extended service intervals in challenging environments.

⭐ Product Features

Water & Dust Proof

NBR contact rubber seals provide IP-class protection against moisture splash, fine dust, and mud — ideal for outdoor and washdown applications.

Grease Retention

Contact seals lock in factory-applied water-resistant grease, preventing lubricant leakage and extending relubrication intervals significantly.

Contaminant Barrier

Rubber lip seals block particles as fine as 0.3mm — far superior to metal shields in dusty, sandy, or muddy operating conditions.

Maintenance-Free

Pre-lubricated for life with premium water-resistant grease. Install and forget — no relubrication needed under normal operating conditions.

Wide Temperature Range

NBR seals perform reliably from -20°C to +100°C. Optional FKM (Viton) seals available for high-temperature applications up to +200°C.

100% Inspected

Every bearing passes noise testing, seal integrity verification, dimensional accuracy checks, and visual quality inspection before shipment.

🔧 Application Scenarios

Washdown Equipment

Food processing conveyors, bottling line rollers, and sanitary equipment exposed to frequent high-pressure washdown cleaning cycles.

Agricultural Machinery

Seeder discs, fertilizer spreader shafts, irrigation pivot rollers, and harvesting equipment operating in dusty, muddy field conditions.

Pool & Spa Equipment

Swimming pool pump motors, spa jet impellers, and water circulation systems requiring moisture-resistant sealed bearings.

Motorcycle & Powersport

Wheel bearings, swingarm pivots, and suspension linkage bearings exposed to road spray, mud, and pressure washing.

Outdoor Power Equipment

Lawn mower spindles, string trimmer heads, pressure washer pumps, and generator bearings exposed to weather and debris.

Marine & Aquaculture

Bilge pump motors, aerator blowers, fish feeder mechanisms, and deck equipment in salt-spray and high-humidity environments.
