Tractor Universal Joint Cross

Product Details

Overview This kit is a universal-joint (UJ) cross replacement kit: typically includes the main cross (the "+" shaped joint), bearing caps/bushings, and inner & outer locking components (locks) which secure the U-joint to the yoke/shaft. For example: "U.J CROSS KIT (38 MM - 1210) WITH GREASE NIPPLE & INNER - OUTER LOCKS FOR Shaktiman & Sonalika rotavator".  The "1210" designation refers to a size/model fitment category (e.g., for shafts of certain diameter, application in rotavator PTO drives). For instance, "Universal Joint Cross 1210" is listed as a rotavator part size.  The "38 mm" in the spec above likely indicates the diameter of the cross/shaft or the bearing cap size (38mm) for that particular kit.   Key Features & Specifications Here are the typical features you should expect: Material & Construction: Made from high-grade alloy steel or heat-treated steel (for example some UJ crosses for rotavators use "Alloy Steel 20MnCr5" material).  Stardened bearing surfaces, high durability to withstand agricultural shock loads. For example one product description mentions hardness ~ 60 HRC. Dimensions / Fitment: Fitment size: "1210" series (so we're looking at cross kits that match the shaft/yoke size for that spec). For the kit specified: 38 mm (diameter) with inner & outer locks. This implies the bearing cap diameter or the cross width is ~38mm.  Intended for certain rotavator makes/models such as Shaktiman & Sonalika. Locking Mechanism: Includes inner locks (which typically secure the bearing caps inside the yoke) AND outer locks (which secure the cross from the outside or serve as external lock rings). Some kits mention "grease nipple" (for re-greasing the cross) though some are "greaseless" versions. E.g., "UJ CROSS KIT 38MM - 1210 W/INNER & OUTER LOCKS … (GREASELESS)".  Usage / Application: Specifically designed for agricultural rotavator shaft universal joints: to connect the PTO shaft or side shaft to the rotor gearbox of a rotavator. For example: one manufacturer lists "Usage/Application: Rotavator" for a Universal Joint Cross 1210.  Robust construction, corrosion resistance, finished polish. For instance: "Offered gear is manufactured using high grade raw materials with the help of progressive technology … Robust construction, Perfect finish".  Ensures correct fitment, prevents misalignment and helps maintain machine life. �� Why this is important on a rotavator The U-joint (cross) is the critical link transmitting rotary motion from the tractor's PTO shaft (and possibly intermediate drives) into the rotor assembly of the rotavator. Any failure here can cause major downtime. Having both inner and outer locks ensures the cross is well secured, reducing risk of slippage, wear or shaft misalignment. Proper fit (1210 size, 38mm) ensures compatibility. Using wrong size may lead to premature failure or shaft damage. The inclusion (or option) of a grease nipple permits maintenance (if greased) – enhancing longevity, particularly in dusty/dirty field conditions.
