Notes about B.....DSA3 Series :
B-DSA-3 series bearings are capable of handling both radial and thrust loads in either direction. They are frequently used in articulating joint applications. Options include tapered bore designs, and they are available in both inch and metric sizes.
Other salient points to be noted :
• Bore dimensions are after MoS2 coating. All other dimensions are before coating.
• For bearings with grooves extended to the face of the outer ring at two places, add suffix “-1” e.g. B3236DSA3-1.
• Ultimate static and impact loads should not exceed 150% of catalog ratings.
* Clearance after shim pack compression.
