• Roller Outside Diameter (D): 1.875 in / 1-7/8" (47.625 mm)
• Inner Bore Diameter (I.D. / d): 0.500 in / 1/2" (12.700 mm)
• Roller Width (B): 1.000 in / 1" (25.400 mm)
• Internal Rolling Layout: Full-Complement Needle Rollers (This cage-less design packs the maximum number of needle rollers inside the casing, providing exceptional radial load-bearing capacity and robust shock resistance).
• Outer Ring Surface Geometry: Cylindrical / Flat (Maximizes physical track-to-roller contact area to distribute heavy workloads evenly across perfectly parallel rails).
• Suffix Designation (PP): Formed dual lip seals on both sides consisting of zinc-plated sheet steel washers with an integrated NBR sealing part. It seals factory grease inside while functioning over a temperature threshold of -30°C to +100°C.
