KH Series: Compact Drawn Cup Linear Ball Bearings

Space‑optimized, low‑friction motion for miniaturized automation
KH Series compact drawn cup linear ball bearing - DISLAB Precision

Designed to solve space-limited motion challenges, KH Series compact drawn cup linear ball bearings feature a unique thin-walled drawn cup structure, delivering stable, low-friction linear reciprocating movement within an ultra-small installation footprint. As a professional industrial component manufacturer, DISLAB Precision develops and produces high-precision KH series linear bushings that perfectly balance compact sizing, reliable operating performance and cost-effectiveness for diverse miniaturized automation scenarios.

Unlike traditional linear bushings, the KH Series is built around a thin‑walled drawn cup outer ring. Engineers prioritizing miniaturization and efficiency gain exclusive advantages: ultra‑compact radial profile, cost‑effective precision, smooth high‑speed operation, and tool‑free press‑fit installation. Whether for multi-axis systems, small gantries, or high-cycle automation, KH Series brings reliable performance into tight mechanical assemblies.

📏 Ultra-Compact Radial Profile
Drawn cup construction reduces outer diameter significantly vs. standard LM series. Perfect for multi‑axis systems and small gantries where every millimeter counts.
💰 Cost-Effective, High-Precision
Drawn cup process delivers reliable precision without high-cost machined housings. Consistent low‑friction motion while keeping budget under control.
🔇 Smooth & Quiet High-Speed
Integrated resin retainer guides recirculating ball rows, ensuring smooth travel and minimizing noise — ideal for high‑cycle automation machinery.
🛠️ Tool-Free Installation
Press‑fit directly into housing bore — no retaining rings or expensive mounting blocks. Cuts assembly time and simplifies your design.
Configurations to Fit Your Application

Standard KH Series

Versatile base model for general industrial use. Metric sizes from 6mm to 50mm. Light‑to‑medium load applications in clean, controlled environments.

Sealed Version (KH..PP)

Equipped with integrated lip seals on both ends to keep dust, debris out while retaining lubrication. Ideal for harsh conditions and long service life.
