Nhông xích thép không gỉ #35 | Tiêu chuẩn ANSI 35 chống ăn mòn

Tổng quan sản phẩm

Cái Nhông xích thép không gỉ Ever-Power #35 bridges the gap between the compact #25 series and the heavier #40 family, delivering a 9.525 mm pitch chain engagement that suits a broad range of medium-duty conveyor, indexing, and drive applications. Machined from solid 304 or 316 stainless bar stock on 5-axis CNC equipment, each tooth profile is generated to ANSI B29.1 form — guaranteeing that your existing ANSI 35 roller chain fits without shimming, grinding, or shimming adjustments. The #35 sprocket is widely used in food and beverage lines where the chain must endure high-pressure steam cleaning and chemical sanitizing cycles that would pit or rust a conventional steel sprocket within weeks.

Thông số kỹ thuật

Chain pitch 9.525 mm, roller diameter 5.08 mm, inner width 4.78 mm. Tooth counts 6T through 60T. Available with plain bore, finished bore with keyway, and taper-lock hub. All contact faces polished to Ra ≤ 1.6 µm. Optional electropolish finish available for ultra-hygienic applications.

Corrosion Resistance in Demanding Environments

The passive oxide layer that forms naturally on stainless steel acts as a self-repairing barrier against oxygen and moisture — unlike paint or zinc coatings, it cannot chip or peel. In practice, this means an #35 đĩa xích thép không gỉ in a vegetable washing line will still look and measure like new after two years of daily chlorine sanitizing washes that would reduce a carbon steel unit to rust-streaked scrap. The 316 variant adds 2–3% molybdenum, closing the vulnerability to chloride pitting that affects 304 in high-salt or HCl environments. For outdoor installations in tropical climates or coastal zones, we also recommend a passivation treatment — a citric-acid bath that strips free iron from the surface and maximises the oxide layer thickness, included at no extra charge on request.

Electropolishing — the Premium Surface Option

Electropolishing removes a thin uniform layer from the metal surface, eliminating micro-peaks where bacteria can colonize. The resulting mirror finish not only looks impressive but quantifiably reduces bacterial adhesion by up to 30% compared to mechanical polishing — a meaningful advantage in pharmaceutical and food applications audited against EHEDG or FDA guidelines. Specify EP finish when ordering if your process validation requires it.

Designing Your #35 Chain Drive System

Getting the most from an #35 stainless roller chain sprocket drive requires attention to a few key parameters beyond just specifying the right pitch. Centre distance determines sag and tension; a centre-to-centre distance of 30–50 pitches is typically optimal for balanced wrap angle and chain tension. Speed ratio should ideally stay below 7:1 on a single stage — beyond that, consider a two-stage reduction to keep tooth loading within safe limits. Lubrication, even for stainless systems, extends chain and sprocket life markedly: food-grade NSF H1 oil applied via drip lubrication or oil bath works well for enclosed drives, while food-grade PTFE dry-film spray is the preferred choice for clean-room and dry environments.
