Thin Section Bearings: Big Performance in Slim Packages

When space is tight but you still need smooth rotation, thin section bearings step up. These slim-profile bearings pack the same durability as standard bearings but in a fraction of the depth—perfect for robotics, aerospace, and medical gear where every millimeter counts.  

Why Go Thin?  

Three scenarios demand these compact workhorses:  

1. Weight savings – Critical in drones and satellites  

2. Space constraints – Fit where conventional bearings won’t  

3. Precision motion – Minimal deflection for sensitive instruments  

Available in inch and metric series (from 1" to 40" diameters), their cross-sections stay ultra-slim while handling radial, thrust, or combined loads.  

Key Applications:  

- Robotic arms – Providing rigid yet low-friction joints  

- CT scanners – Enabling smooth gantry rotation  

- Aircraft controls – Where lightweight reliability is non-negotiable  

Modern versions feature:  

• Corrosion-resistant materials – For surgical tools or marine use  

• Custom preload options – Tuned for zero backlash  

• Hybrid ceramic designs – When electrical isolation matters  

Unlike standard bearings that get bulky under load, thin section models maintain their slender profile while delivering impressive load ratings. The tradeoff? Higher cost per unit—but when the alternative is redesigning your entire assembly, that premium pays for itself.  

For engineers battling space constraints, these bearings prove good things come in thin packages.
