RF-28-PP 1-3/4"-ODa premium, inch-series yoke-type track roller (cam follower).
• 1.750 in / 1-3/4" (44.450 mm)
• Inner Bore Diameter (I.D. / d): 0.500 in / 1/2" (12.700 mm)
• Roller Face Width (W / B): 1.000 in / 1" (25.400 mm)
• Internal Rolling Layout: Full-Complement Needle Rollers. The absence of a traditional separation cage allows the maximum number of needle rollers to be packed inside. This design maximizes radial load capacity and provides high shock resistance.
• Outer Ring Profile: Cylindrical / Flat. The completely flat exterior surface geometry maximizes track contact to evenly distribute intense point-loading forces across straight rails.
