        FAQ<\/h2>\n

        Q1: Where is the AAA456YA2 roller fitted?<\/strong><\/p>\n

        A:<\/strong>\u00a0It is the hanger roller of an Otis landing or car door, the wheel that runs on the hanger track and carries the door panel. Two of them usually carry one panel, so a worn set is normally replaced together. It is a mechanical wear part, not a door operator component.<\/p>\n

        Q2: What does “eccentric” mean here?<\/strong><\/p>\n

        A:<\/strong>\u00a0The roller centre is offset from its mounting point instead of sitting on the axis. That offset is what lets the panel be brought up to the track and set level along its travel. A plain concentric roller of the same diameter will bolt on, but the door cannot be adjusted the same way.<\/p>\n

        Q3: Are AAA456YA1 and AAA456YA4 the same roller?<\/strong><\/p>\n

        A:<\/strong>\u00a0Distributors quote all three codes on the same 85 x 20 mm roller with a 6203 bearing. The suffix letters mark different versions of the same part, not different sizes. Send the code from your old roller and we confirm which one you are replacing.<\/p>\n

        Q4: Which bearing does it use?<\/strong><\/p>\n

        A:<\/strong>\u00a0The 6203RS bearing, the sealed type, as you specified. Some listings for this roller family quote a 6204 bearing; those are wider wheels with a larger bore and will not fit the same hanger. If the old wheel carries a 6202, the wheel you have is not this size, so tell us before ordering.<\/p>\n

        Q5: How do I know the roller is worn?<\/strong><\/p>\n

        A:<\/strong>\u00a0Listen for a rumble or a scraping sound as the door runs, and look for a flat spot on the tread. A worn roller also shows as the panel dragging at the start of travel, or a gap that changes along the track. Check the track and the guide gibs first, because a loose gib imitates a worn roller.<\/p>\n

        Q6: What should I send before ordering?<\/strong><\/p>\n

        A:<\/strong>\u00a0A photo of the old roller in place, so the hanger type is visible. The wheel diameter and width measured across the tread. The bearing number stamped on the seal, and the quantity you need per panel.<\/p>\n","protected":false},"excerpt":{"rendered":"

        AAA456YA2 is the eccentric door hanger roller used on Otis landing and car doors, an 85 mm wheel 20 mm wide running on a 6203RS bearing. The offset centre lets the panel be set against the track, which is why a plain roller will not do the same job. Distributors list it for E311 and E411 installations and also quote it as AAA456YA1 or AAA456YA4. Measure the wheel and read the bearing before ordering.<\/p>\n","protected":false},"featured_media":8361,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[57,153,26,127],"product_tag":[],"class_list":{"0":"post-8360","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-brands-parts","7":"product_cat-elevator-door-system","8":"product_cat-elevator-parts","9":"product_cat-for-otis","11":"first","12":"instock","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/product\/8360"}],"collection":[{"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/comments?post=8360"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/media\/8361"}],"wp:attachment":[{"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/media?parent=8360"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/product_brand?post=8360"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/product_cat?post=8360"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/potensilift.com\/en\/wp-json\/wp\/v2\/product_tag?post=8360"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
