A sheave is the grooved wheel or pulley that seats the drive belt, transferring rotational power from the motor to the spindle through the countershaft assembly. This part maintains correct belt alignment and speed-step selection, which are essential for consistent drilling performance. It is a direct OEM-style replacement intended for installation by machine tool technicians or qualified shop maintenance personnel.\u003c\/p\u003e\n\u003cp\u003eThis countershaft sheave is designed for use with the JET 1200 20-inch drill press. It fits within the belt-drive system housed in the head assembly, where proper sheave condition directly affects spindle speed accuracy and belt service life. Replacement is typically needed when the sheave shows groove wear, cracking, or damage that causes belt slippage or misalignment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM-style countershaft sheave for direct replacement fitment\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with belt-driven drill press countershaft assemblies\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 4 x 4 x 4 inches, suitable for the JET 1200 head housing\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 1 pound for straightforward handling during installation\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the JET 1200 20-inch drill press as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this sheave should be performed by a qualified machine tool technician or experienced maintenance professional. Before servicing, disconnect and lock out all electrical power to the drill press in accordance with applicable OSHA lockout\/tagout procedures.
