S688 8x16x5 mm ステンレス鋼ミニチュア深溝玉軸受

製品概要

S688 Stainless Steel Deep Groove Ball Bearing – 8x16x5mm, Corrosion Resistant. Made of AISI 440C stainless steel with rubber seals (2RS). 低騒音, 高速, and maintenance‑free. 食品機械に最適, 医療機器, 船舶用機器, および精密機器.

主な利点:

• 耐食性
  The most obvious advantage of the S688 over standard 688 (クロム鋼) bearings is its ability to resist rust and oxidation. Made from AISI 440C stainless steel – this bearing can operate in humid environments, direct water spray, steam cleaning, and even mild chemical exposures. It is passivated after grinding to further enhance surface protection. 食品加工用, 海洋, or outdoor applications, the S688 is a reliable, long-term solution.

• 高硬度 & 耐摩耗性
  Unlike low?end stainless bearings that use softer 304 または 316 鋼鉄 (which cannot be through?hardened), AISI 440C is heat treatable to 58–62 HRC. This gives the raceways and balls exceptional wear resistance and load capacity – comparable to standard chrome steel bearings. You don’t have to sacrifice durability for corrosion resistance.

• 低騒音 & スムーズな操作
  精密研磨された軌道と材種 10 (それ以上の) stainless steel balls ensure low vibration and quiet running. This makes the S688 suitable for medical equipment (dental handpieces, surgical saws), laboratory instruments, and any noise-sensitive application. Running noise is typically below 25 dB at moderate speeds.
• コンパクト & 軽量
  With an 8mm bore and only 5mm width, the S688 fits into tight spaces where larger bearings cannot. Its small size and low weight (約. 5 グラム) make it ideal for portable devices, miniature conveyors, and robotic joints.

アプリケーション

• 食品加工装置
  コンベアローラー, 充填機ガイド, bottle capping turntables, dough sheeters, そして肉スライサー. The stainless steel and food?grade grease option meet strict sanitary standards.

• 医学 & 歯科用器具
  Surgical handpieces, 整形外科用のこぎり, 歯科用タービン, 実験用遠心分離機, and fluid pumps. Low noise and smooth rotation are critical here.

• 海洋 & 海中機器
  Underwater cameras, ROV スラスター, boat steering components, および淡水化プラントのバルブ. Saltwater resistance is essential.

• Pharmaceutical Manufacturing
  Tablet press guides, capsule filling machines, and cleanroom conveyors. Stainless steel prevents particle shedding and corrosion from cleaning agents.

• 化学薬品 & Semiconductor Industry
  Wet bench rollers, etching equipment, and chemical pumps where mild acids or alkalis are present.
• アウトドア & Agricultural Automation
  Wet bench rollers, etching equipment, and chemical pumps where mild acids or alkalis are present.
