WM Motor Pully ( S )

Description

The Washing Machine Motor Pulley (“S” / Small Type) is a precision-engineered mechanical component designed to transfer rotational force from the appliance’s electric drive motor to the transmission belt. Often made of high-grade mild steel, cast iron, or lightweight zinc/aluminum alloy, this small-diameter pulley is engineered to maximize high-speed rotational output, making it highly critical for efficient extraction during spin cycles. Equipped with an integrated side-locking nut and bolt mechanism, it locks firmly onto the motor shaft’s flat surface to ensure non-slip performance under sudden torque shifts and high vibrational stress. Key Features & Specifications Type Designation: “S” Type (Small Variant) Shaft Bore Diameter: Available in standard 10mm or 12mm inner diameters (designed to fit flat-sided motor spindles). Material Build: High-tensile mild steel (MS), premium cast iron, or moisture-resistant reinforced alloys. Fastening System: Single or double side-locking bolt/nut configuration for a secure, tight friction fit. Groove Design: Formed with a precise single-groove V-belt profile to reduce friction wear and prevent belt slippage. Compatible Machines & Models The “S” Type small motor pulley serves as a universal or semi-universal replacement part across a vast selection of Semi-Automatic Twin-Tub Washing Machines. It is most commonly utilized on the high-speed Spin Dryer Motors (and select compact wash motors) for the following major brands: Samsung: Universally fits many Samsung semi-automatic twin-tub spin motors that require a smaller drive ratio pulley. Whirlpool: Compatible with classic semi-automatic lineups requiring a tight V-belt groove fit. Godrej & Videocon: Fits a wide array of legacy twin-tub spin motor assemblies with 10mm or 12mm shafts. Haier & Panasonic: Frequently matches the spin actuator spindles on compact to mid-capacity top loaders. 💡 Fitment Check Tip: Because “S Type” small pulleys come in both 10mm and 12mm bore sizes, it is critical to measure the exact thickness of your motor’s shaft with a caliper before replacing it. Ensuring a precise match prevents the pulley from wobbling or failing to slide onto the spindle entirely.
