Machined bearing races, slewing bearings and forged rings have ground surfaces that are susceptible to oxidation and pitting in transit and storage, and manual wrapping cannot hold consistent film tension or uniform overlap across large circumferences.<\/p>\n<h2 id=\"how-the-wrap-is-applied\">How the Wrap Is Applied<\/h2>\n<p>The centre-hole layout suits large bearing races and machined rings requiring VCI corrosion barriers; tooling and wrap material selection per project determine handling for other annular products. The part is threaded over the wrap point, resting horizontally or inclined on motorized support rollers that rotate the workpiece around its vertical axis.<\/p>\n<p>One full rotation then lays a band of film around the whole circumference in a single turn. A reel beside the machine feeds the film. The wrap uses VCI (vapor corrosion inhibitor) film, so the band laid around the ring carries corrosion protection over the part surface. The chemical inhibitors volatilize within the sealed enclosure, passivating the metal surfaces against atmospheric oxidation. The band width, overlap and layer count are set for each job.<\/p>\n<p>For heavy-duty industrial bearings subjected to sea freight or multi-year storage, single-layer wrapping is often insufficient to prevent mechanical abrasion or moisture ingress. Dedicated high-capacity systems such as Model FPCA-6000 can be configured with an optional three-material dispensing carriage [manufacturer rating]. This mechanism mounts three packaging material reels simultaneously, completing a heavy-duty three-layer composite pack in a single continuous run: an internal contact layer of VCI film to inhibit oxidation, followed by two outer layers of high-tensile stretch film to provide mechanical puncture resistance and moisture barrier sealing. Additionally, customized configurations can incorporate an integrated oil reservoir, pumping circuit, and atomizing spray nozzles to apply protective oil directly to the raceways during the wrapping process [manufacturer rating].<\/p>\n<p>The wrap stays even because the same band geometry repeats on every revolution. There is no fixed default. Film width, overlap and pre-stretch are configured per project to match the part and the protection it needs.<\/p>\n<h2 id=\"sizing-film-for-a-ring\">Sizing Film for a Ring<\/h2>\n<p>Three dimensions describe the job: outside diameter OD, inside diameter ID, and section width W of the ring. One pass of the film band travels 2 \u00d7 (W + (OD \u2212 ID) \/ 2).<\/p>\n<p>For an illustrative ring with OD 1.6 m, ID 0.9 m and W 0.3 m, each pass is 2 \u00d7 (0.3 + (1.6 \u2212 0.9) \/ 2) = 1.3 m.<\/p>\n<p>Full cover at the outside diameter needs n = \u03c0 \u00d7 OD \/ (w \u00d7 (1 \u2212 overlap \/ 100)) passes. Here w is the band width, and overlap is a percentage. With a 0.25 m band and 20% overlap, the result is 3.1416 \u00d7 1.6 \/ (0.25 \u00d7 (1 \u2212 20 \/ 100)) \u2248 25.13 passes.<\/p>\n<p>Multiplying the per-pass length by the pass count, Q = q \u00d7 n, gives about 32.67 m of laid film. At a configured 250% pre-stretch the factor is 1 + 250 \/ 100 = 3.5, so each metre from the reel lays 3.5 m on the part. These numbers are illustrative. For an actual order we size the film from your part drawing and the requested overlap.<\/p>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Value<\/th>\n<th>Meaning<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>OD<\/td>\n<td>1.6 m<\/td>\n<td>ring outside diameter<\/td>\n<\/tr>\n<tr>\n<td>ID<\/td>\n<td>0.9 m<\/td>\n<td>ring inside diameter<\/td>\n<\/tr>\n<tr>\n<td>W<\/td>\n<td>0.3 m<\/td>\n<td>ring section width<\/td>\n<\/tr>\n<tr>\n<td>Film band w<\/td>\n<td>0.25 m<\/td>\n<td>band width on the ring<\/td>\n<\/tr>\n<tr>\n<td>Overlap<\/td>\n<td>20 %<\/td>\n<td>coverage overlap between bands<\/td>\n<\/tr>\n<tr>\n<td>Passes n<\/td>\n<td>25.13<\/td>\n<td>passes needed to cover the outside diameter<\/td>\n<\/tr>\n<tr>\n<td>Laid film Q<\/td>\n<td>32.67 m<\/td>\n<td>total film for the example, q \u00d7 n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Note: Values in the table above are [illustrative\/derived] engineering calculations based on theoretical geometric cross-sections.<\/em><\/p>\n<h2 id=\"ring-wrapper-safety\">Controls and Safety for a Ring Wrapper<\/h2>\n<p>These wrappers carry many moving parts \u2014 rollers, clamps, the film feed and the rotating ring \u2014 so the machine shows warning labels. The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method, and EN 415-10 covers the general safety requirements of packaging machines. These two standards form the basis of the guarding and control scheme.<\/p>\n<p>Two points matter in daily use. Keep hands clear of the centre hole and the clamping zone while the unit cycles. Stop the machine and isolate power before adjusting film, clearing a misfeed or working on the load. For maintenance, follow the site lockout and tagout procedure (LOTO) in accordance with plant safety protocols.<\/p>\n<p>A person should not stand beside this machine during normal cycles, and no adjustment or service is performed on a unit that has not been isolated from power. Never reach into the centre opening or past a guard while the machine is running.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<h3>Q: What sets the number of film passes a ring needs?<\/h3>\n<p>A: Ring circumference, band width and overlap. A wider film band cuts the pass count, whereas a higher overlap percentage increases the passes required to ensure complete coverage; the sizing section shows the formula.<\/p>\n<h3>Q: Why does pre-stretch matter on a ring wrap?<\/h3>\n<p>A: It tensions the film before it lands, so one roll covers more ring area and the wrap grips harder. Mechanical elongation thins the film while aligning its polymer chains, which maximizes tear resistance and creates constant compressive force around the ring perimeter.<\/p>\n<h3>Q: Which dimensions should I send with an enquiry?<\/h3>\n<p>A: The outside and inside diameters, the section width, and the overlap you want, which is enough for the pass-count and film-length steps above.<\/p>\n<h3>Q: Can a centre-hole wrapper run in a line?<\/h3>\n<p>A: It depends on the surrounding handling and cycle demand. Layout, infeed height and film options are settled per project, so a line answer starts from a drawing.<\/p>\n<h3>Q: What should a buyer check for on safety?<\/h3>\n<p>A: For CE markets, check the risk assessment follows ISO 12100 and the machine meets EN 415-10; confirm guarding, interlocks and lockout points with the builder.<\/p>\n<h3>Q: What equipment capacity ranges exist for different bearing sizes?<\/h3>\n<p>A: Production equipment scales across distinct size brackets based on part envelope and weight [manufacturer rating]:<\/p>\n<ul>\n<li><strong>Small-to-Medium Rings (Model FPB-400)<\/strong>: Suited for bearing ID 300\u2013800 mm, OD 500\u20131200 mm, width 100\u2013400 mm, and weight 100\u2013500 kg.
