The PX Series solves this by utilizing precision-molded quad-lip X-rings that seal factory-injected lubricant inside the pin-bushing junction while halving the contact friction of conventional round O-rings. \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\" id=\"p-rc_1373e20123afa8b5-39\"\u003e\u003cspan class=\"citation-63 citation-end-63\"\u003eManufactured in Japan, the 520 PX is built with solid bushings, solid rollers, and heat-treated alloy steel link plates that are shot-peened and pre-stretched at the factory to resist initial elongation.\u003csup class=\"superscript\" data-turn-source-index=\"2\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e Quad-stake pin riveting ensures superior mechanical plate retention and fatigue resistance under high shock-load conditions, yielding a rated tensile strength of 8,500 lbs (37.8 kN). \u003cspan class=\"citation-62 citation-end-62\"\u003eThis configuration delivers up to 1.5 times the operational wear life of a standard O-ring chain and up to 12 times the service life of an unsealed drive chain.\u003csup class=\"superscript\" data-turn-source-index=\"3\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e \u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"3\"\u003eFeatures:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003eQuad-Lip X-Ring Seals:\u003c\/b\u003e Retains factory grease while reducing frictional drag by up to 50% compared to standard O-ring designs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003e8,500 lb Tensile Strength:\u003c\/b\u003e Heavy-duty alloy steel construction withstands severe acceleration shock loads and hard landings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003eQuad-Pin Riveting:\u003c\/b\u003e Four-point mechanical staking secures outer plates firmly against pin shear and lateral spreading.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003eSolid Bushing \u0026amp; Solid Roller Design:\u003c\/b\u003e High-precision seamless cylindrical components eliminate seam deformation, extending roller contact life.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,4,0\"\u003e\u003cb data-path-to-node=\"4,4,0\" data-index-in-node=\"0\"\u003ePre-Stretched \u0026amp; Shot-Peened:\u003c\/b\u003e Factory pre-stressing minimizes stretch during break-in, while shot-peened plates resist fatigue cracking.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,5,0\"\u003e\u003cb data-path-to-node=\"4,5,0\" data-index-in-node=\"0\"\u003eMade in Japan:\u003c\/b\u003e Manufactured to Japanese industrial standards for consistent pitch and roller tolerances.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"5\"\u003eWhat's in the Box:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e1x Parts Unlimited 520 PX Series X-Ring Drive Chain (Natural Steel Finish)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e1x Clip-Type Connecting Master Link (Includes master link pin plate, side plate, spring clip, 4x X-rings, and assembly grease packet)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003ci data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003e(Note: Select your required link length from the variant dropdown menu before checkout).\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"7\"\u003eFitment Notes:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003ePitch \u0026amp; Sizing:\u003c\/b\u003e Standard 520 pitch (5\/8\" pin-to-pin, 1\/4\" roller width).
