6807-2RS Thin-Section Deep Groove Ball Bearing For Harsh Environments & Low-Maintenance Systems | 35×47×7 mm

6807-2RS Thin-Section Deep Groove Ball Bearing For Harsh Environments & Low-Maintenance Systems | 35×47×7 mm

Engineered for uncompromising protection, the 6807-2RS is a single-row, thin-section deep groove ball bearing from the 6800 series, equipped with contact rubber seals on both sides. With a 35 mm inner bore and a 47 mm outer diameter, it maintains an ultra-slim 7 mm profile. Unlike open-type variants, this sealed design is purpose-built for external or exposed machinery where the bearing must defend against moisture, dust, and particulate contamination. Factory-packed with premium quality grease, the 6807-2RS locks in its own lubrication for the entirety of its lifespan. By utilizing heavy-duty NBR (Nitrile Butadiene Rubber) seals, this bearing minimizes maintenance requirements, making it the superior choice for space-constrained applications operating in demanding, less-than-clean environments.

6807-2RS Deep Groove Ball Bearing 35×47×7 mm | 68 Series | Sealed Design

A highly resilient, thin-wall bearing constructed for precision mechanisms that demand strict environmental isolation. The sealed architecture of the 6807-2RS completely encloses the rolling elements and raceways, an intentional engineering solution that prevents the ingress of abrasive contaminants while preventing grease leakage. It occupies the exact same 35 × 47 × 7 mm footprint as its open (6807) and shielded (6807-ZZ) counterparts, ensuring a direct, drop-in replacement for existing housings. While open bearings excel in oil-bathed speed, the 6807-2RS trades a slight reduction in maximum RPM for vastly superior longevity and durability in weatherproof, maintenance-free applications.

Comprehensive Applications

The 6807-2RS is the go-to solution whenever a 35 mm shaft requires reliable rotation without the benefit of external system lubrication, particularly when exposed to the elements:

Electric Motors & Power Generation
  • Rotor shaft supports exposed to airborne industrial dust
  • Compact servo motors and stepper motors
  • Alternator and generator components
Light EVs & Cycling Dynamics
  • E-bike bottom brackets and wheel hubs requiring strict weatherproofing
  • Electric scooter transmission housings
  • Suspension pivot points
Robotics & Automation
  • External robotic joints operating in dusty manufacturing facilities
  • Conveyor belt rollers and automated assembly line guides
  • AGV (Automated Guided Vehicle) wheel assemblies
Power Tools & Handheld Equipment
  • Spindle supports designed to resist sawdust and metal shavings
  • Heavy-duty landscaping and agricultural equipment sensors

Key Performance Features

01. Compact Yet Highly Durable

Belonging to the thin-section 6800 family, the tight 35 mm to 47 mm bore-to-OD ratio grants engineers the freedom to design equipment with large, rigid shafts without requiring bulky external housings. Despite its slim 7 mm width, it reliably supports significant radial loads up to 4.75 kN.

02. Superior Contaminant Exclusion

The implementation of double-sided NBR contact seals ensures the 6807-2RS forms a tight physical barrier against the outside world. This lip-seal design effectively wipes the inner ring as it rotates, keeping water, mud, and microscopic abrasives entirely out of the internal raceway, drastically reducing premature mechanical wear.

03. Lifetime Lubrication for Zero-Maintenance

Because the dual seals trap the lubricant inside the bearing cavity, the 6807-2RS comes pre-filled with a precise amount of high-performance grease. This "lubricated-for-life" configuration completely eliminates the need for complex relubrication systems, saving on engineering costs and downtime.

Interchange Part Numbers

The 6807-2RS is globally standardized and cross-referenced under the following manufacturer-specific suffix conventions for double-sealed variants:

  • SKF: 61807-2RS1 / 61807-2RSH
  • NSK: 6807 DDU / 6807 VV
  • FAG (Schaeffler): 61807-2RSR

  • NACHI: 6807 2NSE
  • Generic / Welink: 6807-2RS, 61807-2RS, 6807RS

Design & Configuration

Operating as a Conrad-type, single-row radial ball bearing, the 6807-2RS is uniquely optimized for environments where spatial economy and dirt resistance must coexist. It relies entirely on its integral NBR sealing components to manage its internal environment, making external housings simpler and cheaper to manufacture. The internal geometry yields a 4.75 kN dynamic load rating and a 3.80 kN static capacity. While seal friction slightly lowers its thermal threshold compared to open types, it still comfortably sustains rotational speeds of approximately 8,000 r/min. For fully immersed oil-bath applications, a standard 6807 Open should be utilized. However, for standalone components exposed to the atmosphere—where keeping factory grease in and destructive elements out is the primary goal—the 6807-2RS is the definitive engineering choice.

"When a 35 mm shaft operates in a contaminated or moisture-prone environment, yet housing dimensions remain strictly limited, the 6807-2RS thin-section bearing provides the ultimate maintenance-free solution. Its robust sealed architecture ensures continuous, reliable rotation for modern robotics, EVs, and outdoor power equipment."
