Product detail
The Thomson 511H20C0 is a 500 Series profile rail ball carriage (bearing block) designed to deliver smooth, precise linear motion in demanding applications.
This narrow-block style carriage works with 20 mm profile rails and offers a clearance preload (i.e., nominal clearance without initial preload) for general-purpose motion.
With precision-ground recirculation paths, low-drag seals, and an optimized geometry for smooth motion, it ensures stable and quiet performance across a wide range of speeds and operating conditions.
Highlight Feature
Thomson’s enhanced 500 series carriages incorporate improved surface interfaces between steel and plastic in the ball-circulation zones and feature better contaminant protection via robust end seals.
⚙️ Key Features
-
500 Series, Narrow Block Style: Compact footprint with robust load capacity.
-
Clearance Preload (C0): Standard configuration for smooth motion with minimal internal friction.
-
High Load Ratings: Dynamic and static load capacities suited for demanding motion systems.
-
Enhanced Seals & Recirculation Design: Improved end seals offer better protection against contaminants; molded circulation paths minimize drag.
-
Interchangeable with Previous 500 Series: New design is backward compatible with earlier Thomson 500 series carriages and rails.
-
Wide Operating Temperature Range: Suitable for –40°C to +80°C typical industrial conditions.
-
Optimized Geometry for Quiet & Smooth Operation: Reduced drag and vibration during travel.
