Ball Transfer Unit KSM NL series

Product Overview

The NL series ball transfer units are flat embedded omnidirectional conveying parts customized for low-height spaces and thin worktables. Different from conventional high-profile ball units, they adopt a low and compact structure, specially designed for ultra-thin workbenches, micro conveying equipment and precision tooling devices. Made of high-quality carbon steel with chrome plating, the product features a mirror-bright smooth surface with uniform and full plating layer. It is rust-proof, corrosion-resistant and scratch-resistant, with an exquisite and clean appearance, perfectly matching high-definition white-background main image display for independent websites, balancing practicality and visual texture.

Material & Craftsmanship

The housing is made of high-strength carbon steel, precisely stamped, hard chrome electroplated and mirror polished. The high-hardness surface is wear-resistant, rust-proof and anti-oxidation, adapting to humid and dry alternating industrial workshop environments. The core rolling balls adopt high-precision bearing steel with quenching hardening and mirror polishing treatment, featuring ultra-low rolling resistance and smooth rotation. The internal precision assembly structure ensures uniform gaps, no jamming and no ball falling, with stable overall performance and longer service life than ordinary economical ball units.

Structure & Performance Advantages

Featuring an exclusive ultra-low flat design, NL series minimizes mounting height and solves the installation problem of conventional ball units on thin plates and low tooling tables. Adopting standard press-fit installation, it can be firmly fixed by direct pressing after hole drilling, with simple assembly, tight fitting and anti-loose performance. 360° omnidirectional rotation supports arbitrary translation, steering and fine adjustment of workpieces with quiet and stable operation without scratching precision parts. The enclosed dustproof structure effectively isolates dust and debris to prevent internal jamming, suitable for long-term continuous automatic operation in various light-duty and precision conveying scenarios.
