SKF 6207 2RS C3 GJN 35x72x17 mm Ball Bearing

Technical Overview & Key Features

Sealed, Pre-Greased Ball Bearing for Heavy-Duty Industrial Use

The SKF 6207 2RS C3 GJN bearing measures 35 mm (inner diameter) x 72 mm (outer diameter) x 17 mm (width). It features dual rubber seals (2RS) for protection against dust, debris, and moisture, an internal clearance rated C3 to accommodate thermal expansion and vibration, and is filled with GJN high-temperature polyurea grease — ensuring stable, low-friction operation over extended service intervals even under harsh conditions.

Advantages & Typical Applications

High Load Capacity, Long Service Life and Versatile Use

• Sealed and protected unit — 2RS sealing shields internal components from contaminants while retaining lubricant, crucial for dusty, wet or harsh environments.

• High temperature and maintenance-free grease (GJN) — factory-filled with polyurea-based grease that stays stable over wide temperature ranges, reducing maintenance needs and prolonging bearing life.

• C3 clearance for thermal and dynamic tolerance — the increased internal clearance compensates for heat expansion, shaft misalignment or variable loads, ensuring reliable operation under fluctuating conditions.

• Robust load handling, smooth rotation — capable of carrying significant radial loads and moderate axial loads, while deep groove geometry ensures low friction, stable rotation, and minimal vibration.

• Wide industrial applicability — suitable for electric motors, pumps, gearboxes, drives, conveyor rollers, manufacturing machinery, HVAC units and other heavy-duty equipment needing dependable bearing performance.

Detailed Product Description

The SKF 6207 2RS C3 GJN 35x72x17 mm deep groove ball bearing represents a premium, ready-to-install bearing solution designed for demanding industrial applications. Its dual-seal (2RS) construction guards against contamination, keeping lubricant intact and protecting internal rolling elements from dust, metal particles, moisture, or other harmful agents — which is critical in harsh operational environments such as production halls, agricultural equipment, or HVAC systems.

Pre-filled with GJN high-temperature polyurea grease, this bearing is optimized for long service life and minimal maintenance. The grease remains effective across a broad temperature range and under dynamic loads, ensuring smooth and reliable rotation over extended intervals. This is especially valuable in continuous operation settings, heavy-duty motors, or machinery with limited maintenance access.

The C3 internal clearance further enhances the bearing’s adaptability: it compensates for thermal expansion, vibration, and shaft misalignment — factors that often reduce bearing lifespan. Combined with deep groove geometry and hardened steel components, the 6207 2RS C3 GJN ensures high radial load capacity, stable rotation, low noise and low vibration under both static and dynamic loads.

Its versatile load-handling capabilities and robust protection make this bearing suitable for a broad range of applications: from electric motors and pumps to conveyors, gearboxes, agricultural machinery, HVAC units, compressors, industrial fans, and any mechanical assembly requiring a reliable, long-lasting bearing solution.

Because it adheres to standard dimensions and comes factory-greased and sealed, SKF 6207 2RS C3 GJN is ready for direct installation — on shafts or within bearing housings — without additional preparation. That makes it particularly valuable for OEMs, maintenance departments, and B2B clients seeking reliable, maintenance-free bearing solutions.

FAQ - Frequently Asked Questions

Q: What does the GJN suffix mean in this bearing’s designation?
A: GJN indicates the bearing is pre-filled with high-temperature polyurea grease, designed for long service life under variable temperatures and heavy-duty conditions.

Q: Is the 2RS sealing effective in dusty or wet environments?
A: Yes — the dual rubber seals prevent dust, particles, water and other contaminants from entering the bearing, while keeping the grease inside for smooth operation.

Q: Why is C3 internal clearance important?
A: C3 clearance provides extra radial space to compensate for thermal expansion, vibration or misalignment — reducing stress on bearing components and increasing reliability under dynamic conditions.

Q: What types of loads can this bearing handle?
A: The bearing is designed for radial loads and moderate axial loads, making it suitable for motors, gearboxes, pumps, compressors, conveyors and heavy-duty industrial machinery.

Q: Is this bearing ready to install out of the box?
A: Yes — standard dimensions, pre-filled grease and sealed design mean the bearing can be mounted immediately on shaft or in housing, without additional preparations.
