Frequently Asked Questions (FAQs)

1. What is the difference between ball bearing and insert bearing?

The main difference between ball bearings and insert bearings is that insert bearings can handle larger loads compared to standard ball bearings. Insert bearings also have a simpler lubrication process and offer multiple locking options, such as a squeeze collar, eccentric lock collar, or a set screw lock.

2. How are ball bearings attached to the shaft?

Ball bearings are typically attached to the shaft using locknuts. Special spanners are used to tighten these locknuts securely. Another method of mounting bearings on shafts is by using hydraulic nuts, which provide a hydraulic force to secure the bearing in place.
