High Light Single Row Flat Cage Needle Roller BearingLinear Needle Roller Assembly 3.5x25mmPlanar Linear Sliding Guide Bearing
1. Product Overview

FF-3525 belongs to standard FF series flat linear needle roller assembly. It is composed of cylindrical needle rollers installed inside a flat nylon retainer, single row arrangement.

This component is installed between two flat raceway surfaces to achieve reciproing linear sliding movement. It only bears vertical radial load and cannot be used for rotary motion. The retainer evenly separates rollers to avoid collision friction and maintain stable sliding performance.

FF stands for single-row structure; FFZW represents double-row type. Widely used for precision moulds, automation linear guide structures, testing equipment and low-speed flat reciproing machinery.

Formal quotation will be sent within 24 hours upon your inquiry.
