SMR105 5X10X4 mm 2RS Hybrid Ceramic Ball Micro Fishing Reel Bearings

SMR105 Hybrid Ceramic Fishing Reel Bearings – Precision Performance for Anglers

The SMR105 bearing is a “miniature – stainless steel – double-sided contact seal” deep groove ball bearing, specially designed for harsh fishing environments such as seawater, high humidity, and dust.

Key Features:

• Stainless steel base
  The bushings/rolling elements are made of stainless steel and undergo vacuum quenching and tempering. The salt spray test is ≥ 48 hours. They still maintain high corrosion resistance in seawater and acidic/alkaline environments.

• Double rubber seals
  One-piece double-sided seal, forming a slight interference with the inner ring, preventing dust, salt spray, and sand particles, and preventing lubricant leakage; the leakage rate in freshwater/seawater immersion tests is < 0.1%.

• Low starting torque, low noise
  The internal part is filled with food-grade low-viscosity synthetic ester lubricating grease. The starting torque is ≤ 0.05 N·cm, and the noise level is Z1 group. During the feeding/receiving process, the hand feels smooth without any “stalling” abnormal noise.

• High limit rotational speed
  The grease lubrication limit rotational speed is 50,000 r/min, meeting the rapid throwing requirements of high-speed spinning wheels and water drop wheels at 8,000–10,000 rpm.
• Maintenance-free, long life
  The sealed bearing has a “lifelong lubrication” structure. In regular fishing use, no grease replenishment is required for 2–3 quarters.

Applications

• Marine/ freshwater fishing equipment
  Spinning wheel shafts, water droplet wheels, drum wheels, raft wheels, long-range throwing wheels, line wheel main shafts, cranks, one-way bearings, clutches.

• Miniature rotors
  Rotating shafts in lures (shimmers, VIB, Minos), rotating shackle rings.

• Small underwater equipment
  Waterproof camera shafts, miniature motors of fish finder propellers.

• Small motors in corrosive environments
  Marine miniature pumps, model propellers, fans of salt spray test chambers.
