Step 1: Define the Load Condition

• Radial load: the dominant force perpendicular to the shaft.
• Axial (thrust) load: force along the shaft axis.
• Combined / moment load: requires a bearing designed for mixed loading.

Step 2: Match the Material to the Environment

For wet, corrosive, or hygienic duty, choose stainless or ceramic construction. For maximum load at low cost, chrome steel remains the default. SINO BEARINGS supplies all of these from one source.

Step 3: Select Precision and Sealing

• Precision: P0/P6 for general use, P5/P4 for spindles and instruments.
• Seals: 2RS for contamination protection, ZZ for high speed, open for sealed housings.

Step 4: Verify Sizing

Confirm bore, outer diameter, and width against your shaft and housing. Deep Groove Ball Bearings from SINO BEARINGS cover bore 3 mm to 150 mm, 60/62/63/68/69 series, with custom sizes available on request.
