Unlike painted aluminium housings that suffer paint flaking in chlorinated washdown environments \u2014 creating a contamination risk \u2014 the 304SS construction is inherently corrosion-resistant and eliminates paint as a contamination vector entirely. Surface finish is electro-polished for cleanability.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>IP69K Washdown Protection<\/h4>\n<pee>Sealed to IP69K \u2014 the highest ingress protection rating available. The gearbox withstands high-pressure (80-100 bar), high-temperature (80 degrees C) close-range washdown jets used in meat, dairy, and pharmaceutical facilities. This exceeds the IP66 rating common on standard industrial gearboxes and eliminates the need for protective covers during cleaning cycles.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>VITON (FKM) Oil Seals<\/h4>\n<pee>All shaft seals use VITON fluoroelastomer (FKM) as standard \u2014 not NBR. VITON resists the caustic cleaning chemicals (sodium hydroxide, peracetic acid, chlorine) used in food industry CIP and COP procedures that destroy NBR seals within weeks. Temperature range: -20 degrees C to +200 degrees C continuous.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>20CrMnTi Worm Shaft with Zi Profile<\/h4>\n<pee>The worm shaft is machined from 20CrMnTi alloy steel with a Zi-profile tooth form (involute globoid). Carburised case depth 0.8-1.2 mm, surface hardness HRC 58-62. The Zi profile provides optimised contact geometry for higher load capacity and lower noise compared to standard ZA or ZN profiles.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>CuSn12Ni2 Bronze Worm Wheel<\/h4>\n<pee>The worm wheel uses CuSn12Ni2 nickel-tin-bronze \u2014 a higher-performance alloy than the standard CuSn10Pb1 used in general-purpose gearboxes. The 2% nickel content increases tensile strength and corrosion resistance, making it specifically suited for food-grade environments where trace lubricant contact with product is a regulatory concern.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>Food-Grade Lubricant & O-Ring Seal<\/h4>\n<pee>Factory-filled with NSF H1 registered food-grade synthetic lubricant, safe for incidental food contact per FDA 21 CFR 178.3570.

Unlike painted aluminium housings that suffer paint flaking in chlorinated washdown environments \u2014 creating a contamination risk \u2014 the 304SS construction is inherently corrosion-resistant and eliminates paint as a contamination vector entirely. Surface finish is electro-polished for cleanability.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>IP69K Washdown Protection<\/h4>\n<pee>Sealed to IP69K \u2014 the highest ingress protection rating available. The gearbox withstands high-pressure (80-100 bar), high-temperature (80 degrees C) close-range washdown jets used in meat, dairy, and pharmaceutical facilities. This exceeds the IP66 rating common on standard industrial gearboxes and eliminates the need for protective covers during cleaning cycles.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>VITON (FKM) Oil Seals<\/h4>\n<pee>All shaft seals use VITON fluoroelastomer (FKM) as standard \u2014 not NBR. VITON resists the caustic cleaning chemicals (sodium hydroxide, peracetic acid, chlorine) used in food industry CIP and COP procedures that destroy NBR seals within weeks. Temperature range: -20 degrees C to +200 degrees C continuous.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>20CrMnTi Worm Shaft with Zi Profile<\/h4>\n<pee>The worm shaft is machined from 20CrMnTi alloy steel with a Zi-profile tooth form (involute globoid). Carburised case depth 0.8-1.2 mm, surface hardness HRC 58-62. The Zi profile provides optimised contact geometry for higher load capacity and lower noise compared to standard ZA or ZN profiles.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>CuSn12Ni2 Bronze Worm Wheel<\/h4>\n<pee>The worm wheel uses CuSn12Ni2 nickel-tin-bronze \u2014 a higher-performance alloy than the standard CuSn10Pb1 used in general-purpose gearboxes. The 2% nickel content increases tensile strength and corrosion resistance, making it specifically suited for food-grade environments where trace lubricant contact with product is a regulatory concern.<\/pee><\/div>\n<p> <\/p>\n<div class=\"feat-card\">\n<h4>Food-Grade Lubricant & O-Ring Seal<\/h4>\n<pee>Factory-filled with NSF H1 registered food-grade synthetic lubricant, safe for incidental food contact per FDA 21 CFR 178.3570. An additional O-ring on the input flange face provides a secondary moisture barrier, preventing cleaning solution ingress through the motor-to-gearbox interface during high-pressure washdown.<\/pee><\/div>\n<p> <\/div>\n<p><\/div>\n<\/section>\n<p><\/p>\n<section class=\"section\">\n<div class=\"wrap\"> <span class=\"section-label\">Stainless Steel Series<\/span> <\/p>\n<h2 class=\"section-title\">Other Models in This Series<\/h2>\n<p> <pee class=\"section-subtitle\">The EPSS stainless steel range covers centre distances from 30 mm to 63 mm.<\/pee> <\/p>\n<div class=\"related-grid\"> <a href=\"\/it\/product\/epss-030-stainless-steel-worm-reducer\/\" class=\"rel-card\"><\/p>\n<h4>EPSS 030<\/h4>\n<pee>30 mm CD | SS304<\/pee><\/a> <a href=\"\/it\/product\/epss-040-stainless-steel-worm-reducer\/\" class=\"rel-card\"><\/p>\n<h4>EPSS 040<\/h4>\n<pee>40 mm CD | SS304<\/pee><\/a> <a href=\"\/it\/product\/epss-050-stainless-steel-worm-reducer\/\" class=\"rel-card current\"><\/p>\n<h4>EPSS 050<\/h4>\n<pee>50 mm CD | SS304<\/pee><\/a> <a href=\"\/it\/product\/epss-063-stainless-steel-worm-reducer\/\" class=\"rel-card\"><\/p>\n<h4>EPSS 063<\/h4>\n<pee>63 mm CD | SS304<\/pee><\/a> <\/div>\n<p><\/div>\n<\/section>\n<p><\/p>\n<section class=\"cta-bar\">\n<div class=\"wrap\"> <\/p>\n<h2>Need a Stainless Steel Worm Reducer for Your Food Line?<\/h2>\n<p> <pee>Send us your motor specifications, ratio requirement, and washdown protocol.
