• Roller Outside Diameter (D): 1.3750 in / 1-3/8" (34.925 mm)
• Roller Face Width (C/B): 0.750 in / 3/4" (19.050 mm)
• Stud Fitting Diameter (\(d_{s}\)): 0.500 in / 1/2" (12.700 mm)
• Thread Profile: 1/2-20 UNF
• Internal Layout: Cage-guided needle rollers (Provides lower rotational friction for lower operating temperatures and faster speed capacities than full-complement types).
• Outer Ring Profile: Cylindrical / Flat (Maximizes surface contact area to spread heavy workloads evenly along linear pathways).
• Weight: ~0.34 lbs (0.16 kg)
