FAQ
Q1: What loads can single row angular contact ball bearings bear?
A: They withstand combined radial load and one-way axial load. To bear bidirectional axial force, two or more bearings need to be installed in paired arrangement (DB/DF/DT).
Q2: Can angular contact ball bearings work at high speed?
A: Yes. Optimized internal structure enables high-speed operation. Open type bearings generally achieve higher limiting speed than sealed 2RS versions.
Q4: What’s the difference between brass cage and nylon (PA66) cage?
A: Brass cage (M) adapts to high temperature, high speed and harsh working conditions.
Nylon PA66 cage features low noise, good shock absorption, fit for normal temperature general machinery.
Q5: Are sealed angular contact bearings reusable after disassembly?
A: Not recommended. Sealed models are pre-filled with grease. Disassembly will damage the sealing structure and lead to grease leakage, affecting service life.
