This is a genuine Makita ball bearing for chainsaws, supplied to replace OEM No. 211111-8. It is a precision steel bearing that supports rotating shafts and reduces friction inside the saw’s drive system, helping the tool run smoothly and efficiently. Made from hardened steel for strength and wear resistance, it is suitable for demanding cutting work and regular use. The bearing helps maintain alignment and smooth rotation of key components, which in turn reduces heat, noise, and premature wear. Designed for Makita electric chainsaws, it is a direct-fit service part for models such as the UC3530A and UC4051A, restoring correct operation after noise, roughness, or play is detected in the original bearing. Genuine part status ensures correct sizing and dependable compatibility.

Key Features:
– Genuine Makita replacement bearing for OEM No. 211111-8, ensuring the correct fit and function
– Precision steel construction for durability and consistent performance under load
– Reduces friction to support smooth, efficient rotation and steady chain drive
– Helps cut vibration and noise from worn bearings, improving user comfort and cut quality
