The SYZ-HSB-NS024 is a not-shouldered industrial weld-on ball joint built for heavy-duty fabricated linkage, control arm, steering, cylinder connection, and weld-in joint applications.
Pin size is 1.75 in, retainer OD (B) is 4.5 in, ball width (C) is 2.5 in, and retainer width (D) is 11/16 in.
The SYZ-HSB-NS024 lists two angle references: Angle A is 20° and Angle B is 28°, reflecting the wider misalignment range of the not-shouldered design.
The SYZ-HSB-NS024 lists an ultimate retainer strength of 162000 lbs and a ball push-out force of 68600 lbs.
The housing is 45# carbon steel, zinc plated, the ball is 52100 bearing steel / 45# carbon, hard plated, heat treated, and material references given for the joint include GCr15 / 52100, carbon steel, zinc coating, black oxide, chrome plated options. It uses a metal to metal, with grease nipple or oil hole optional construction for custom welded assemblies.
The SYZ-HSB-NS024 is the not-shouldered type in this series — shouldered joints (part numbers ending -S###) add a shoulder feature to the housing, while not-shouldered joints (ending -NS###) omit it; both are sized by pin diameter and retainer OD, so match the type your weld fixture and clearance require.
