High-Precision Thin-Walled Deep Groove Ball Bearing 61917

Ultra-Slim Design
– Only 18mm thickness for compact installations without sacrificing load capacity. Ideal for space-constrained applications like robotics and medical devices.
Premium Materials
– Chrome steel construction with optional 2RS rubber seals or ZZ metal shields for enhanced durability and contamination resistance in industrial environments.
Laser-Engraved Accuracy
– Precision-ground raceways and balls ensure smooth rotation (ABEC-1 standard), reducing friction in high-speed machinery like CNC spindles.
Multi-Protection Options
– Choose open, shielded (6917Z/ZZ), or sealed (2RS) variants for dustproof, low-noise, or grease-retention needs in automotive transmissions.
Global Bulk Supply
– Direct factory pricing for wholesale buyers. Ships in OEM packaging with 85x120x18mm exact sizing for seamless replacements in conveyor systems.
Cross-Industry Versatility
– Fits aerospace actuators, electric motors, and agricultural equipment where weight savings matter. Made for engineers who demand reliability.
