The ring then rotates through the bearing bore while the bearing turns, so the material spirals around the full ring section. After wrapping, a cutting system cuts the material and the outfeed conveyor carries the bearing away.<\/p>\n<p>Sensors detect the bearing position to start and stop the machine automatically. In our video, the ring carries green material through the bore of a large roller bearing while the bearing turns, so each wrap overlaps the last until the whole section is covered.<\/p>\n<figure>\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.fhopepack.com\/blog\/wp-content\/uploads\/2025\/06\/automatic-bearing-packing-line-for-EU-customer4.webp\" alt=\"Automatic bearing packing line with ring wrapper, roller conveyors and control panel\" width=\"1236\" height=\"1216\" class=\"skip-lazy\">\n<figcaption><strong>Automatic bearing packing line.<\/strong> Roller conveyors feed bearings to the ring wrapper.<\/figcaption>\n<\/figure>\n<h2 id=\"models\">FPB-300 or FPB-400<\/h2>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>FPB-300<\/th>\n<th>FPB-400<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Bearing OD<\/td>\n<td>600\u20131,200 mm<\/td>\n<td>500\u20131,200 mm<\/td>\n<\/tr>\n<tr>\n<td>Bearing ID<\/td>\n<td>300\u2013900 mm<\/td>\n<td>300\u2013800 mm<\/td>\n<\/tr>\n<tr>\n<td>Bearing width<\/td>\n<td>20\u2013300 mm<\/td>\n<td>100\u2013400 mm<\/td>\n<\/tr>\n<tr>\n<td>Bearing weight<\/td>\n<td>10\u2013500 kg<\/td>\n<td>100\u2013500 kg<\/td>\n<\/tr>\n<tr>\n<td>Ring speed<\/td>\n<td>30\u201370 r\/min<\/td>\n<td>30\u201370 r\/min<\/td>\n<\/tr>\n<tr>\n<td>Wrap time<\/td>\n<td>40\u201350 s per bearing<\/td>\n<td>30\u201350 s per bearing<\/td>\n<\/tr>\n<tr>\n<td>Overlap<\/td>\n<td>20\u201380%<\/td>\n<td>20\u201390%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Choose by width first. Bearings wider than 300 mm need the FPB-400, and narrow bearings under 100 mm wide need the FPB-300. Bearings with an ID over 800 mm also need the FPB-300.<\/p>\n<h2 id=\"overlap\">Overlap at the OD<\/h2>\n<p>Wraps spread furthest apart at the outer diameter, so overlap is smallest there. We set the overlap at the OD so the outside has no gaps. The listed wrap time limits how many wraps fit. At 70 r\/min, 50 s allows 70 \u00d7 50 \u00f7 60 \u2248 58 wraps.<\/p>\n<p>Illustrative example for a 1,000 mm OD bearing with 100 mm material:<\/p>\n<table>\n<thead>\n<tr>\n<th>Overlap at OD<\/th>\n<th>Advance per wrap<\/th>\n<th>Wraps<\/th>\n<th>Time at 70 r\/min<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>50%<\/td>\n<td>50 mm<\/td>\n<td>\u03c0 \u00d7 1,000 \u00f7 50 \u2248 63<\/td>\n<td>about 54 s<\/td>\n<\/tr>\n<tr>\n<td>30%<\/td>\n<td>70 mm<\/td>\n<td>\u03c0 \u00d7 1,000 \u00f7 70 \u2248 45<\/td>\n<td>about 38 s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>At 50% overlap, this bearing runs just over the listed 50 s.

Up to 6 programs can be stored in the PLC memory and selected from the keypad. That makes changeovers between bearing sizes quick.<\/p>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>FPB-300<\/th>\n<th>FPB-400<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Control<\/td>\n<td>PLC and HMI<\/td>\n<td>PLC, keypad, 6 stored programs<\/td>\n<\/tr>\n<tr>\n<td>Positioning<\/td>\n<td>automatic, sensor detected<\/td>\n<td>automatic centralised<\/td>\n<\/tr>\n<tr>\n<td>Modes<\/td>\n<td>manual and automatic<\/td>\n<td>automatic<\/td>\n<\/tr>\n<tr>\n<td>Speed<\/td>\n<td>frequency converter<\/td>\n<td>converters<\/td>\n<\/tr>\n<tr>\n<td>Fault display<\/td>\n<td>indicator light alarm, causes shown<\/td>\n<td>not listed on its page<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"materials\">Materials<\/h2>\n<p>Both models take goffered paper, PE, stretch film, knit belt or PVC.
