A short, stubby, hollow cylindrical metal part with a high-luster, silvery-white metallic finish (presumably hardened bearing steel, stainless steel, or an alloy part with a highly polished surface). Its outer surface is extremely smooth, and its inner bore is precision-machined to be fully through; the overall shape resembles a thick-walled sleeve or a miniature roller. It is closely associated with components such as bushings, cylinder pins, groove pins, and control levers, and is typically used as a rotating or sliding sleeve for cam followers, guide rail supports, or the outer surfaces of pins. Specific materials and tolerances are subject to the official BOM.
Applications
1. Cam follower wheels in Krones filling valve assemblies; guide rollers for the capping head’s lifting/clamping linkage; track support rollers at the transfer points of the bottle-washing turntable star wheels; and contact sleeves for the positioning control points of feedback rollers or probes on the directional control cylinders of conveyor guide rails.
2. Typically mounted as a loose sleeve on a Cylinder Pin (0724512241) or Groove Pin (0723411242) and a bushing (0902045966), serving as the end contact element for control levers or rocker arms, working in conjunction with cam surfaces, guide rails, or spring mechanisms to achieve high-frequency follow-up motion.
3. Specific installation levels, mating shaft diameters, outer diameters, and widths must be verified against official assembly drawings and pneumatic/mechanical schematics.
Functions
1. Low-friction tracking: Converts sliding friction between mechanisms into rolling friction (or acts as an extremely smooth sliding bearing), significantly reducing drive resistance and wear.
2. Guidance and load-bearing: Under high-speed alternating loads, provides precise physical limiting, support, and reset reference along a fixed trajectory or guide rail.
3. Pin Protection: Acting as an easily replaceable, consumable outer ring, it directly absorbs external scratches and impacts, protecting the internal precision pins and lever bores from rapid wear.
Features
1. High-rigidity polished metal components combine core toughness with extremely high surface hardness, making them suitable for production line conditions involving high-frequency micro-movements, compression, and frequent impacts (specific material grades and heat treatment are subject to official specifications).
2. The surface finish of the outer diameter, the roundness of the inner bore, wall thickness uniformity, and edge chamfers directly determine rotational flexibility, control accuracy, and overall service life.
3. These components are subject to regular inspection due to high-frequency friction and impact: Common failures include scuffing, scratches, or out-of-roundness on the outer diameter; increased wear in the inner bore; chipped or curled edges; complete seizure preventing rotation; or surface rust and coating peeling, leading to abnormal noise and sluggish operation.
Maintenance/Replacement Guidelines
Carefully inspect the outer surface for a smooth finish without deep scratches; check the inner bore for ovality or scuffing; ensure the component rotates smoothly without binding; and inspect the edges for material loss, cracks, or surface peeling and buildup. When replacing, strictly verify part number 0900787461, as well as the inner diameter, outer diameter, width, and chamfer dimensions. Before installation, clean the mating pins and associated bushings; gently push them into place to protect the inner bore and chamfers; apply food-grade lubricant as needed or install anti-loosening devices as required. After reassembly, first manually verify that rolling and sliding movements are free of binding and that the trigger points are accurate; then operate at low speed up to normal line speed to confirm there are no abnormal noises, vibrations, or operational delays.
