Engineers, robotics builders, and RC hobbyists working with space-constrained assemblies need a bearing that delivers full deep-groove performance in a dramatically reduced envelope. These super thin-wall sealed deep groove ball bearings are engineered exactly for that challenge.\u003c\/p\u003e\n\u003cp\u003eEach bearing in this series features a chrome steel (GCr15) raceway and ball set, enclosed by dual steel shields (ZZ) that retain grease and block particulate ingress without adding significant width. The series spans seven sizes — 6700ZZ through 6706ZZ — with bore diameters from 10 mm (0.394 in) to 30 mm (1.181 in), outer diameters from 15 mm (0.591 in) to 37 mm (1.457 in), and a uniform 4 mm (0.157 in) width across the entire range. Available in quantities of 1, 4, or 10 pieces per order.\u003c\/p\u003e\n\u003cp\u003eTypical applications include brushless motor front\/rear bearing seats in RC cars and drones, joint pivot points in lightweight robotic arms, spindle support in compact medical instruments, and idler pulley assemblies in 3D printer extruder carriages — anywhere a thin-wall deep groove ball bearing for precision machinery is required.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard 6700–6706 series bearing seats.

They are not designed for heavy axial-only applications — for those, a thrust bearing or angular contact bearing would be more appropriate. Exact dynamic and static load ratings vary by size; contact us for specific values.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre the ZZ shields removable for re-lubrication?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe ZZ steel shields on these bearings are snap-fit and can be carefully removed with a thin pick for re-lubrication, though this requires care to avoid distorting the shield. For most applications, the factory grease fill is sufficient for the bearing's service life. If your application demands frequent re-lubrication, consider specifying an open or rubber-sealed (2RS) variant instead.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings suitable for outdoor or wet environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThe dual steel shields provide basic splash resistance and keep grease in place, but chrome steel raceways are susceptible to corrosion if exposed to standing water or high-humidity environments over extended periods. For outdoor or wash-down applications, consider stainless steel bearings or apply a compatible corrosion inhibitor. These bearings are well-suited for indoor machinery, RC vehicles, and electronics where moisture exposure is incidental rather than continuous.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I know if a 6700-series bearing is compatible with my motor or spindle?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eCheck your motor or spindle datasheet for the bearing seat dimensions: shaft diameter (ID), housing bore (OD), and axial space (width). Match those to the variant you select. The 6700ZZ series is a globally standardized designation, so any bearing labeled 6700ZZ, 6701ZZ, etc., will share the same envelope dimensions regardless of brand — making direct substitution straightforward.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eShould I buy 1 Pcs, 4 Pcs, or 10 Pcs?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eChoose 1 Pcs for prototyping or single-unit repairs where you need to verify fit before committing.

They do not touch the inner ring, so friction is slightly lower and maximum speed is higher compared to rubber seals. 2RS (or RS, RZ) refers to rubber contact seals that provide better contamination exclusion at the cost of slightly higher drag. For high-speed, low-contamination environments — such as brushless motors and encoders — ZZ is typically the preferred choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-cta\"\u003e🛒 Select your Size and Amount above, then add to cart.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"HomeDIYer","offers":[{"title":"6700ZZ 10x15x4mm \/ 1Pcs","offer_id":52410081509650,"sku":"FXL43-0","price":2.16,"currency_code":"USD","in_stock":true},{"title":"6700ZZ 10x15x4mm \/ 4Pcs","offer_id":52410081542418,"sku":"FXL43-1","price":3.11,"currency_code":"USD","in_stock":true},{"title":"6700ZZ 10x15x4mm \/ 10Pcs","offer_id":52410081575186,"sku":"FXL43-2","price":5.1,"currency_code":"USD","in_stock":true},{"title":"6701ZZ 12x18x4mm \/ 1Pcs","offer_id":52410081607954,"sku":"FXL43-3","price":2.3,"currency_code":"USD","in_stock":true},{"title":"6701ZZ 12x18x4mm \/ 4Pcs","offer_id":52410081640722,"sku":"FXL43-4","price":3.52,"currency_code":"USD","in_stock":true},{"title":"6701ZZ 12x18x4mm \/ 10Pcs","offer_id":52410081673490,"sku":"FXL43-5","price":6.05,"currency_code":"USD","in_stock":true},{"title":"6702ZZ 15x21x4mm \/ 1Pcs","offer_id":52410081706258,"sku":"FXL43-6","price":2.43,"currency_code":"USD","in_stock":true},{"title":"6702ZZ 15x21x4mm \/ 4Pcs","offer_id":52410081739026,"sku":"FXL43-7","price":4.07,"currency_code":"USD","in_stock":true},{"title":"6702ZZ 15x21x4mm \/ 10Pcs","offer_id":52410081771794,"sku":"FXL43-8","price":7.41,"currency_code":"USD","in_stock":true},{"title":"6703ZZ 17x23x4mm \/ 1Pcs","offer_id":52410081804562,"sku":"FXL43-9","price":2.71,"currency_code":"USD","in_stock":true},{"title":"6703ZZ 17x23x4mm \/ 4Pcs","offer_id":52410081837330,"sku":"FXL43-10","price":5.43,"currency_code":"USD","in_stock":true},{"title":"6703ZZ 17x23x4mm \/ 10Pcs","offer_id":52410081870098,"sku":"FXL43-11","price":11.08,"currency_code":"USD","in_stock":true},{"title":"6704ZZ  20x27x4mm \/ 1Pcs","offer_id":52410081902866,"sku":"FXL43-12","price":2.84,"currency_code":"USD","in_stock":true},{"title":"6704ZZ  20x27x4mm \/ 4Pcs","offer_id":52410081935634,"sku":"FXL43-13","price":5.78,"currency_code":"USD","in_stock":true},{"title":"6704ZZ  20x27x4mm \/ 10Pcs","offer_id":52410081968402,"sku":"FXL43-14","price":12.23,"currency_code":"USD","in_stock":true},{"title":"6705ZZ  25x32x4mm \/ 1Pcs","offer_id":52410082001170,"sku":"FXL43-15","price":3.39,"currency_code":"USD","in_stock":true},{"title":"6705ZZ  25x32x4mm \/ 4Pcs","offer_id":52410082033938,"sku":"FXL43-16","price":8.01,"currency_code":"USD","in_stock":true},{"title":"6705ZZ  25x32x4mm \/ 10Pcs","offer_id":52410082066706,"sku":"FXL43-17","price":18.35,"currency_code":"USD","in_stock":true},{"title":"6706ZZ  30x37x4mm \/ 1Pcs","offer_id":52410082099474,"sku":"FXL43-18","price":3.39,"currency_code":"USD","in_stock":true},{"title":"6706ZZ  30x37x4mm \/ 4Pcs","offer_id":52410082132242,"sku":"FXL43-19","price":8.01,"currency_code":"USD","in_stock":true},{"title":"6706ZZ  30x37x4mm \/ 10Pcs","offer_id":52410082165010,"sku":"FXL43-20","price":18.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Picture2of11_5285cd31-35dc-4d8f-b2b6-bdea77da11c2.jpg?v=1782372229","url":"https:\/\/homediyer.com\/products\/super-thin-wall-sealed-bearings-steel-deep-groove-ball-bearing-6700zz-6706zz","provider":"HomeDIYer","version":"1.0","type":"link"}
