Laifual FSS is a precision harmonic reducer. This record represents the manufacturer's C-I component set in frame size 11, as identified in its model-specific dimensional drawing. Specifications preserve the listed reduction-ratio configurations, separate rated, starting/stopping and instantaneous torque limits, input speeds, backlash, mass and design-life qualifiers. Manufacturer drawing and web-table discrepancies are flagged in the affected specification conditions. Cover image: Manufacturer series image; size may vary.
Product family: Laifual FSS C-I harmonic reducers

YOUR PRIVACY
How this website uses information, and the choices you can make.
Last updated: .
Robotuo is responsible for the personal information processed through this website.
This policy covers browsing Robotuo, local preferences, and our planned use of Google Analytics through Firebase and OneSignal web push notifications. These optional services only run when enabled on the site and you have agreed to the relevant category.
You can browse without an account or agreeing to optional services. Our hosting provider receives your IP address, requested URL, browser information, and request time to deliver and protect the site. Our basis for this processing is our legitimate interest in operating a secure, reliable website.
We store your privacy choices in this browser so we can respect them. This essential preference includes the policy version, your choices, and when you made them; it is not sent to an analytics service. Hosting and security logs are separate from these browser settings.
With your consent, “Remember my selections” stores comparisons and followed companies and products in this browser. These are not synced to an account or shared with Google or OneSignal by our integration. Without consent, these features still work for the current page session.
Turning this option off deletes saved selections from local storage. Current selections remain in memory until you reload or close the page.
With analytics consent, we use the Google Analytics web stream linked to our Firebase project to understand which parts of Robotuo are used and improve the website. Google processes online identifiers, cookie identifiers, browser and device information, general page categories, and usage events. IP addresses are used by Google during collection, including to derive approximate location.
Our integration uses general page categories rather than search terms, full query strings, or individual company and product identifiers. With analytics consent, we also measure visits attributed to recognized AI services and confirmed Connect requests from those visits. We send a fixed provider label and page category, without sending the original referral URL or form contents. Attribution lasts only within the current page session and may be incomplete. We do not send application form contents, names, or email addresses to Analytics. Advertising consent remains off; Google signals and advertising personalization are disabled in our integration.
The Google tag is not loaded before analytics consent. Declining analytics does not enable cookieless analytics pings. Learn more in Google’s Privacy Policy and Firebase’s privacy information.
With notification consent, OneSignal helps us deliver Robotuo news and updates. It processes subscription and device identifiers, push tokens, browser and operating system information, IP address, language, and notification delivery and interaction information. This service may use browser storage and a service worker to deliver notifications even when the website is closed.
Saving consent does not grant browser permission. Open Privacy settings, save your notification choice, then select “Enable notifications” and allow notifications in your browser if prompted. You can withdraw consent here or block notifications in your browser’s site settings.
Withdrawal disables further SDK data collection and attempts to unsubscribe this browser from push messages. It does not automatically erase information already held by OneSignal. See OneSignal’s Privacy Policy.
Our essential robotuo-privacy record is kept in local storage and is valid for 180 days. We ask again when it expires or the consent version changes. Saved selections use robotuo-compare, robotuo-catalog-follows, robotuo-product-follows, and robotuo-follow-labels; they stay until you withdraw that choice, your consent expires, or you clear site data.
When analytics is enabled with consent, Google uses cookies such as _ga and _ga_*. Our integration limits these cookies to 180 days without automatic renewal. Withdrawing analytics consent disables collection and removes accessible Analytics cookies for this site. Cookie expiry is separate from the retention of data already received by Google.
OneSignal stores subscription information in browser storage and its service worker. Vendor-held records and hosting logs follow the retention settings and obligations applicable to those services; withdrawing consent does not itself delete previously collected records. You can request erasure where applicable.
Use “Reject all,” “Accept all,” or individual choices in Privacy settings. Optional categories are off by default. Closing settings or continuing to browse does not give consent. The Privacy settings button is available in the footer throughout the site. Withdrawing consent is as easy as giving it and does not affect the lawfulness of processing before withdrawal.
Where the GDPR or UK GDPR applies, you may request access, correction, erasure, restriction, or portability of your personal information and object to processing based on legitimate interests. You may complain to your local data protection authority. We normally respond to rights requests within one month, subject to applicable extensions and identity verification.
Privacy contact details will be published before optional services are activated.
Clearing browser data resets these choices. To stop push notifications, also disable notification permission in your browser; clearing site data alone may not withdraw permission. Choices apply to this browser, not every device you use.
Our hosting provider, Google, OneSignal, and the browser’s push delivery provider may process technical information needed for their respective services. Processing may take place outside your country, including in the United States. Where required, transfers need appropriate safeguards, such as applicable adequacy decisions or standard contractual clauses. You may request information about safeguards that apply to your data.
Saved selections, analytics, and notification processing rely on your consent. We do not sell the information collected through these features or use it for advertising in this integration.
Search terms filter content in your browser and may appear in the page URL. Avoid entering sensitive information into search. Application and issue-report drafts stay in this page until you choose Send. Sending shares the information you entered and the relevant page with Robotuo through our hosting provider and Feishu, where our team reviews it and follows up. Do not include sensitive personal information. These submissions work independently of optional analytics and notification preferences.
To limit repeated requests, our server processes your IP address and stores a keyed hash with short-lived counters. When deployed with our shared Upstash Redis store, it stores these hashes, submission identifiers and delivery state for up to 24 hours; form contents are not stored there. Application and report records remain in Feishu for team review and follow-up. Contact Robotuo about access or deletion using the contact information in this policy.
Reloading or closing the page clears unsent drafts. Visit previews do not send a booking. Company websites and the Robot Valley booking page are separate websites with their own privacy practices. Review their policies before submitting personal details.
