SMR117 7x11x3mm Stainless Steel Hybrid Ceramic Fishing Reel Miniature Bearing

SMR117 Hybrid Ceramic Bearings – Unlock the Full Potential of Your Fishing Reel

The SMR117 stainless steel hybrid ceramic bearing is engineered to transform your fishing reel’s performance, delivering longer casts, smoother retrieves, and unmatched durability in the harshest saltwater and freshwater environments.

主な特長:

1. Ultimate Corrosion Resistance
   AISI 440C stainless steel is specifically engineered for demanding bearing applications. Unlike austenitic stainless steels (304, 316) that are softer and cannot be through-hardened, 440C combines excellent corrosion resistance with high hardness and strength, making it the ideal material for fishing reel bearings that must survive salt spray, saltwater immersion, and repeated freshwater rinsing.

2. 摩擦の低減, Smoother Operation, Lower Maintenance
   Ceramic balls have an ultra-smooth, non-porous surface that requires less lubrication than steel equivalents. Si3N4 ceramic bearings generate less heat and lower vibration levels, reducing friction as the spool revolves.The silicon nitride material also has self-lubricating properties, so even under marginal lubrication conditions, the bearing continues to spin smoothly and consistently.

3. Wear Resistance
   Si3N4 ceramic is one of the hardest engineering materials available, with hardness exceeding that of steel by a significant margin. This extreme hardness provides exceptional wear resistance, resisting pitting, spalling, and surface fatigue far longer than steel balls under the same operating conditions.

4. Higher Temperature Tolerance
   Your reel’s spool spins at extremely high speeds under heavy drag pressure, generating significant heat. Standard steel bearings can soften, expand, or lose lubrication under these conditions. Si3N4 ceramic balls maintain their hardness and dimensional stability at temperatures exceeding 300°C, far beyond what any fishing reel will ever encounter.
5. Extended Service Life
   According to industry data, hybrid ceramic bearings can achieve 3 に 5 times the service life of conventional all-steel bearings under comparable operating conditions.The lighter weight of ceramic balls reduces centrifugal load on the cage and raceways, while the extreme hardness eliminates surface fatigue that causes bearing failure in steel components.
6. Multiple Sealing Options for Your Specific Environment
   The SMR117 is available in several sealing configurations to match your fishing conditions:

ZZ (Double Metal Shields) – Offers excellent dust protection while allowing very high rotational speeds. Ideal for freshwater fishing where water exposure is minimal.

2RS (Double Rubber Seals) – Provides superior protection against water, salt spray, and fine sand infiltration. The rubber seals also retain lubricant more effectively, reducing maintenance frequency. This is the recommended configuration for saltwater anglers.

Open (No Shields) – Maximum speed potential, suitable for controlled environments or for anglers who prefer to lubricate their own bearings frequently.
