Feature: 1. This one-way bearing rotates freely in one direction and locks in the opposite direction. 2. Made of GCr15 bearing steel, it has a hardness of HRC61-65 after heat treatment, compact size, and high load capacity. 3. Designed with ample space for grease storage, providing extended lubrication intervals and reliable performance. 4. Effectively locks the drive shaft when receiving driving force, improving upon the limited locking performance of traditional stamped outer ring one-way bearings. 5. Commonly used in textile machinery, printing machinery, automotive applications, household appliances, currency detectors, and more.
