Product Overview<\/h2>\n
\n
\n \"Medical\n <\/div>\n
\n

Medical stainless steel spur gears<\/strong> are the highest-precision variant in Korea Ever-Power’s spur gear range \u2014 precision-machined in stainless steel across module M0.15 to M2.0, in a continuous scale of sub-ranges from the finest pitch (M0.15\u2013M0.2) through instrument and light-industrial sizes (M0.25\u2013M2.0). The spur gear form transmits motion between two parallel shafts \u2014 since the tooth surface is parallel to the axis of the mounting shaft, no axial thrust force is generated. This property, combined with the ease of achieving high accuracy in small-module stainless steel gears, makes the spur form the standard choice for medical instrument drives, surgical robot mechanisms, infusion pump gear trains, and diagnostic equipment actuators.<\/p>\n

Korea Ever-Power holds ISO 9001:2008 and TS16949 certification and has been manufacturing precision medical stainless spur gears<\/a> since 2008. The factory is located in Hangzhou, Zhejiang Province \u2014 factory visits welcomed, with hotel booking assistance and airport pickup available. Minimum order quantity is 1 set. ODM and OEM service. Vacuum-packed in plastic tray, delivered by DHL and UPS.<\/p>\n<\/p><\/div>\n<\/div>\n

Stainless steel spur gears are preferred over brass, POM, or alloy steel in medical applications where corrosion resistance to body fluids, cleaning agents, and sterilisation conditions must be demonstrated across the gear’s full service life \u2014 including the tooth flank surface, which is subject to rolling\/sliding contact wear and cannot be reliably protected by a surface coating. At the module sizes used in medical instruments (M0.15\u2013M1.5), stainless steel machining achieves tooth surface quality and accuracy levels comparable to brass \u2014 unlike at large module sizes where stainless steel’s lower machinability becomes a significant factor.<\/p>\n

Key Features<\/h2>\n

\"Ever-Power<\/p>\n

\n
\n

No Axial Thrust \u2014 Simple Bearing Arrangement<\/h3>\n

The spur gear tooth surface is parallel to the mounting shaft axis \u2014 no axial force component is generated during meshing. In compact medical instrument mechanisms where shaft support is provided by miniature ceramic or SS bearings, the elimination of axial thrust directly reduces bearing loading and mechanism complexity, allowing smaller, lighter bearing selection without thrust capacity requirements.<\/p>\n<\/p><\/div>\n

\n

High Precision \u2014 AGMA 13 \/ DIN 5<\/h3>\n

Medical instrument drives require low transmission error \u2014 deviation of the output angle from the theoretically correct angle introduces reading or positioning error that directly affects the medical device’s functional accuracy. AGMA 13 (\u2248 DIN 5) stainless spur gears minimise this transmission error. High-precision stainless steel spur gears can be manufactured with high precision because the straight tooth profile of the spur gear is simpler to cut accurately than helical or bevel teeth.<\/p>\n<\/p><\/div>\n

\n

Corrosion Resistant in Sterilisation Environments<\/h3>\n

Stainless steel (particularly SS316L with its molybdenum content) resists pitting corrosion in chloride-containing sterilisation agents (chlorine-based disinfectants, saline solutions). The gear’s corrosion resistance is intrinsic to the base material \u2014 unlike coated steel, which loses its protection as the coating wears from the tooth flanks in service, stainless steel maintains dimensional and surface integrity throughout the gear’s service life.<\/p>\n<\/p><\/div>\n

\n

Non-Magnetic \u2014 MRI and Electromagnetic Compatibility<\/h3>\n

Austenitic stainless steel grades (SS304, SS316L) are non-magnetic in the annealed state. Medical devices used in or near MRI scanners must use non-magnetic materials in all components \u2014 a stainless steel spur gear satisfies this requirement while providing the structural rigidity and surface hardness that plastic gears cannot match at the same size and load.<\/p>\n<\/p><\/div>\n

\n

Vacuum Tray Packaging \u2014 Contamination Protection<\/h3>\n

Vacuum-packed in plastic tray packaging prevents surface contamination, particle deposition, and moisture condensation between production and installation in the medical device assembly line. The vacuum environment also prevents the slight surface tarnish that can form on stainless steel during storage \u2014 ensuring the polished tooth flanks arrive in the condition they left the factory.<\/p>\n<\/p><\/div>\n

\n

ISO 9001 \/ TS16949 Certified<\/h3>\n

ISO 9001:2008 and TS16949 certification cover the quality management system, process controls, and inspection procedures. Both certificates are accepted as supplier qualification evidence at medical device OEM incoming inspection \u2014 eliminating the need for additional supplier auditing in most markets. TS16949 automotive certification provides an additional level of process rigour that exceeds the minimum ISO 9001 requirement.<\/p>\n<\/p><\/div>\n<\/div>\n

Frequently Asked Questions<\/h2>\n
\n
\n

Is Korea Ever-Power a manufacturer or trading company?<\/p>\n

Korea Ever-Power is a manufacturer \u2014 established in 2008, with a factory at No. 35, Zijing Road, Hangzhou City, Zhejiang Province, China, near Hangzhou Xiaoshan Airport. The facility manufactures medical stainless spur gears directly under ISO 9001:2008 and TS16949 quality management systems. Factory visits are welcome \u2014 Korea Ever-Power provides airport pickup and hotel booking assistance for visiting customers.<\/p>\n<\/div>\n

\n
\n

What is the minimum order quantity?<\/p>\n

Since these are mechanical precision components, the minimum order quantity is 1 set. For prototype and development orders where only a single gear set is required for mechanism validation, Korea Ever-Power produces and delivers at MOQ 1 \u2014 without requiring minimum batch commitment. This makes the medical stainless spur gear service accessible for new product development programmes where a single sample set is needed before the production tooling decision is made.<\/p>\n<\/div>\n

\n
\n

How do I confirm the non-magnetic property of stainless steel spur gears?<\/p>\n

The non-magnetic property of austenitic stainless steel (SS304, SS316L) is measured by Feritscope \u2014 a portable ferrite content measurement instrument. A reading of \u2264 2 Ferite number confirms the non-magnetic condition suitable for MRI-adjacent applications. Korea Ever-Power can provide the Feritscope measurement report for each batch of medical stainless spur gears where the non-magnetic property is specified. Specify “non-magnetic confirmation required \u2014 Feritscope measurement report” on the drawing or order, and the report will be included with the delivery documentation.<\/p>\n<\/div>\n

\n
\n

Can I visit the factory before placing a production order?<\/p>\n

Yes \u2014 factory visits are welcome at any time. The Korea Ever-Power factory is in Hangzhou, near Hangzhou Xiaoshan Airport. Korea Ever-Power provides airport pickup on arrival and can book a hotel for the duration of the visit. Factory tour covers the CNC gear cutting department, heat treatment facility, quality inspection laboratory (CMM and optical measurement instruments), and finished product storage. Contact Korea Ever-Power with your planned travel dates to arrange the visit schedule.<\/p>\n<\/div>\n

\n
\n

What SS316L properties make it preferred over SS304 for medical spur gears?<\/p>\nSS316L adds 2\u20133% molybdenum to the SS304 composition, which significantly improves pitting corrosion resistance in chloride-containing environments \u2014 specifically relevant for medical devices exposed to saline (0.9% NaCl), chlorhexidine disinfectants, and hypochlorite sterilisation solutions. The “L” designation means low carbon (\u2264 0.03% C), which reduces sensitisation (chromium carbide precipitation at grain boundaries) during the welding and sterilisation heat cycles. For dental instruments and surgical tools subjected to repeated autoclave cycles, SS316L is the standard specification. For general medical automation where chloride exposure is not a primary concern, SS304 is adequate and slightly more cost-effective. Contact our team<\/a> to confirm the appropriate SS grade for your specific application.<\/p>\n<\/div>\n<\/div>\n
