It has a specified shaft diameter of 89.85 mm, bore diameter of 106 mm and height of 8 mm. The seal helps retain grease and reduce the entry of dirt and other contaminants into moving pin joints. Caterpillar lists this part for multiple excavator models, including the CAT 320, 330, 336 and 349 series. Final compatibility should be confirmed by machine serial number and parts diagram before ordering.<\/p>\n<h3 id=\"what-this-part-does\">Qual \u00e9 a fun\u00e7\u00e3o desta pe\u00e7a?<\/h3>\n<p>Excavator linkage pins operate under heavy loads and repeated movement. Grease helps protect the contact surfaces between pins and bushings, but dirt and abrasive particles can accelerate wear.<\/p>\n<p>The CAT 166-1495 Pin Seal is designed to retain grease within the joint while limiting external contamination. During operation, controlled grease movement helps flush contaminants away from the sealing area.<\/p>\n<p>A damaged or incorrectly fitted pin seal can allow grease loss and dirt entry, potentially increasing wear on linkage pins and bushings.<\/p>\n<h3 id=\"key-features\">Principais caracter\u00edsticas<\/h3>\n<ul>\n<li>Steel-faced rubber lip seal construction<\/li>\n<li>CAT Type NB pin seal<\/li>\n<li>Designed for greased oscillating linkage joints<\/li>\n<li>89.85 mm specified shaft diameter<\/li>\n<li>106 mm bore diameter<\/li>\n<li>8 mm seal height<\/li>\n<li>Helps retain grease and reduce contamination<\/li>\n<li>Suitable for specified CAT excavator and heavy equipment applications<\/li>\n<\/ul>\n<h3 id=\"technical-specifications\">Especifica\u00e7\u00f5es T\u00e9cnicas<\/h3>\n<table>\n<thead>\n<tr>\n<th><strong>Especifica\u00e7\u00e3o<\/strong><\/th>\n<th><strong>Detalhes<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>N\u00famero da pe\u00e7a<\/strong><\/td>\n<td>166-1495<\/td>\n<\/tr>\n<tr>\n<td><strong>Varia\u00e7\u00e3o da pesquisa<\/strong><\/td>\n<td>1661495<\/td>\n<\/tr>\n<tr>\n<td><strong>Tipo de produto<\/strong><\/td>\n<td>Pin Seal<\/td>\n<\/tr>\n<tr>\n<td><strong>Seal Design<\/strong><\/td>\n<td>Steel-Faced Rubber Lip Seal<\/td>\n<\/tr>\n<tr>\n<td><strong>Seal Type<\/strong><\/td>\n<td>NB<\/td>\n<\/tr>\n<tr>\n<td><strong>Shaft Diameter<\/strong><\/td>\n<td>89.85 mm \/ 3.54 in<\/td>\n<\/tr>\n<tr>\n<td><strong>Bore Diameter<\/strong><\/td>\n<td>106 mm \/ 4.17 in<\/td>\n<\/tr>\n<tr>\n<td><strong>Altura<\/strong><\/td>\n<td>8 mm \/ 0.31 in<\/td>\n<\/tr>\n<tr>\n<td><strong>Listed Materials<\/strong><\/td>\n<td>Carbon Steel, Plastic, Urethane Rubber<\/td>\n<\/tr>\n<tr>\n<td><strong>Lubrifica\u00e7\u00e3o<\/strong><\/td>\n<td>Grease<\/td>\n<\/tr>\n<tr>\n<td><strong>Aplica\u00e7\u00e3o<\/strong><\/td>\n<td>Linkage Pin Joints<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Specifications are based on Caterpillar public parts information.
